Min-Max: Sal's Kid's 2010 Intense Tracer

Fabricated Fondness

I think my favourite part of the min-max series is the familiar if a bit fatigued way that some folks describe their submissions. Examples? Bean said their Salsa Timberjack is a "boring sleeper." In explaining why he's still riding his Banshee, Dave says: "to be honest, I've been looking at upgrading to a new bike for a few years, but have yet to find the right machine." Sal calls this project that he lovingly assembled for his son "a hodgepodge of my bike clutter and imagination." On the surface these descriptions are rather deprecating but the underlying fondness that min-max participants have for their rigs is undeniable.

My appreciation is personal. We can't all be Daniele making dream eyes at his 2013 MDE. Whether he continues to ride it or the frame eventually becomes a wall-mounted combination of art piece and memory bank, it's clear that if he ever had a Viking funeral, that Italian-made aluminum steed would be on a flaming ship beside him. Sometimes I look at my mountain bike and I'm stoked that it will probably be getting pedaled around long after I'm dust. Other times I feel taunted by the fact that overbuild hardtail beast is going to be with me 'til kingdom come.

Sal is most likely stressing in the opposite direction. He's clearly put a ton of work into the 2010 Intense Tracer he assembled for his son, including a full bearing kit as part of the painting process. But he's also facing the universal law of children and sporting equipment: they always grow out of it before you're ready for them to. One cool thing about this rig is that Sal's kid is most likely going to grow out of it size-wise before he grows out of it due performance needs.

Fox Float RP23 Boost Valve shocks were so under-appreciated. Think about what folks asked these tough little inline trail shocks to do on 5-6” travel bikes!

This version of the Tracer is the last generation before they went to swap-outs that allowed for different axle options, but has fairly similar geometry to the next generation Tracer 2 models. The frame has a 1.5" (49/49) head tube and 140-150mm (5.5-6") of travel, with the longer travel setting also getting slacker geometry. In the 150mm setting the head tube angle (HTA) sits at 67.5" and the actual seat tube angle (STA) is 71.5°. The nominal bottom bracket height would sit around 340mm depending on tires. For those that never had an opportunity to throw a leg over the Intense bikes of this era, their vpp system was actually VPP* at the time and within any travel category they ride very similarly to the bikes Santa Cruz was selling.

*Virtual Pivot Point (VPP) is one example of a virtual pivot point (vpp) suspension system.

Under that paint is an Easton aluminum semi-hydroformed tubeset with the shapes pressed and the frame welded at Intense's facility in Southern California. When this bike came off the production line it was still a couple years before Intense started their transition to overseas manufacturing by pitting their unique in-house aluminum heritage against the generically organic shapes of other-party produced plastic fantastic. It's a decision that's often brought to the front of my mind by the cool USA-made mules that the current DH team rides versus what you can buy.

Custom Flair

Sal describes himself as a tinkerer by nature and this Tracer served multiple purposes. His son had grown out of his 24" Kona Shred, and Sal was looking for a pandemic project anyway. He would troll the various bicycle buy-and-sell sites for possible bargains and came up with this Intense. The frame was beaten cosmetically, but it's running smooth after a full frame pivot/bearing service that was a necessary part of the custom paint job anyway. Sal assembled a spray booth in his garage, with tarps and a bathroom fan, sanded down the frame, primed it, and then painted it with rattle can enamels. Sal's kid appreciates the custom paint and the ground up build and that's rad. I also think it turned out great, but that doesn't really matter.

Remember when these Shimano XT M785 brakes came on every bike regardless of the drivetrain spec? An exaggeration I know, some came with the four-piston Saint/Zee equivalents (ha).

Greatest Hits

The rest of the build is a proper mish-mash of parts representing "a hodgepodge of [Sal's] bike clutter and imagination." It's hard to get too in depth with 'upgrade' ideas for this reason. Clearly it's a rolling chassis that will see parts swapped as needed. The 49/49 head tube means there's an opportunity to fire in a -2° angleset and see how much that changes the ride.

The Fox Float RP23 Boost Valve shocks were wicked little inline units that could take a beating and performed quite well given that a lot of frames they were mounted in were quite wonky suspension wise, and they were regularly featured on longer travel bikes being ridden hard. On that note another recommendation I'd have is to stay on top of service. All the seal kits are still available, however once any hard parts wear out it's going to be searching for a new shock - which will be substantially more expensive than a service. Same goes for the fork.

One item I would upgrade is the pedals. There are a number of smaller sized platform pedals that could work for a ten-year-old. I'd be looking for something lower profile (ground clearance) and with more traction for wet winter rides. You don't have to break the bank - Kona now makes a 'Small' version of their excellent Wah Wah 2 Composite pedal that I think would fit the bill. I've killed the bearings in my Wah Wah 2s so I'm about to find out if the bodies - which are looking rough but are actually still quite usable - will take another set of guts. They don't owe me anything so it would be a nice added value.

Race Face Aeffect cranks are everywhere. These, and now the Aeffect R, with their Cinch ring interface and 24mm spindle are my min-max favourite.

The Tracer is sporting a pair of Shimano XT master cylinders with an XT caliper up front and a Deore caliper in the rear. The rear hub is also a Deore unit while the front is actually an anodized blue Hope hub and those are laced to a pair of Mavic rims. It's an XT 11-speed transmission as well, not bad for a 10-year-old's needs. The only problem is that once they get used to Dual-Release Shimano stuff their cheaper shifting setups just don't feel as nice. Hook 'em young I guess but I know from my own experience that shifters are one places I really, really, notice the difference on budget-friendly bikes.

The crankset is a Race Face Aeffect which (now replaced by the Aeffect R) has long been my min-max favourite. Cinch chainring interface, 24mm steel spindle, and they share the solid appearance of their higher-end siblings. When the chainring is toast there are a host of replacement options. When the cassette finally kicks the bucket the temptation may be to replace it with a SunRace, but an even more obvious choice is whatever Sal has hanging around. SunRace cassettes are a solid value, but on the average 10-year-old's allowance, free is the big win.

Filling out the Fox-RaceFace portion of the build is the Fox Transfer dropper post. It's a 100mm unit. I will say that the Transfer is the absolute best fixed-cable externally routed dropper that I've used. Yes, the rider will get centimeters more travel for the same height by going to a OneUp but that would also require modifying the frame to add an exit port for the dropper cable. If the Transfer was already around, great, but the other advantage of the OneUp is the adjustable max travel so that the post can grow with your kid. They're currently the best dropper posts for short(er) people, and I'm confident that Sal could make that exit port.

Min-max. Keep the suspension serviced, buy some nicer pedals, replace the cassette with a SunRace when it dies. I’d let my friends riding 49/49 (1.5”) headtube frames with anglesets know that I’d be interested in a swap if they ever sell their frame.

The world of 26" tires, and really 26" specific anything, is interesting these days. It's a bit crazy when you consider how many kids' bikes still come set up with 26" as a bridge between 24" and 27" wheels, or as a transition point on bikes that can also run smaller or larger hoops. This rig would be equipped with a pair of 26" Maxxis DHF tires, and that would still be Sal's preference in the future, but these Bontrager tires were a cheap buy-and-sell find and really, in these days, any deal on rubber is a win!

I've been saying since my kid started riding that her first full suspension bike would be the first bike she buys, and pays to service, for herself. What can I say, hardtails make sense to me for kids, teens, and adults on a budget. Or really on any budget when the application is such that the extra service costs don't justify the performance increase. But, I think Sal killed it with this project on a frame that is thirteen years old and it is the sort of project that my progeny and I are into tackling, so maybe I should keep a more open mind.

Oh, this is good. This is very, very good.

I always appreciate the moxy of a good ol' garage and bathroom fan paint booth setup. Plus it sounds like he avoided 2 component clears on this job so we don't have to get out the personal safety pitchforks.

This is a great article... Few thoughts as someone who has been providing my now 11 year old twin (yet massively different sizes) boys with used min/maxed bikes since they were 4...

24" vs 26" vs 27.5".  Are all valid sizes as kids grow... my one 11 year old is on the "small" side... and could finally fit a 26" wheel sized bike this year.  No way he'd fit any of the small or extra small 27.5 frames.  But most importantly, moving him from 24" wheels to 26" made a huge improvement in his speed, climbing abilities and descending confidence.  Will get him on 27.5 when it's possible.

Drilling a hole in an aluminum frame to give yourself access to a much larger range of dropper posts (new and used) is definitely the way to go.  Did that to my son's 26" bike this spring and it was much easier that I thought... wow is aluminum ever soft!!  Watch a youtube video and go for it.  Even step it up a level, drill two holes, file the space between and buy one of those proper rubber oval grommets and make it look factory.

As soon as you can find the right and available sunrace cassette (they have one for everything) ditch the stupid shimano cassette with the huge jump to the lowest gear.

And, go full 46t... paired with a 30t or even 28t chainring, your kid will have zero excuses when it comes to climbing!!

On that note, it's surprising just how many of those older little shimano derailleurs can handle a 46t cassette (or 42 if you're moving from 36).  Just pick-up some longer b screws from the hardware store... works great.

Note on chainline... sometimes with kids and smaller bikes and really short chainstays... moving to a 42 or 46t cassette can cause some backpedal issues where the chain likes to dump 8 gears with one backpedal.  Switching to a 6mm (often referred to as GXP) offset ring can help quite a bit.

Another note... extra-small and small 27.5 frames can easily run 26" wheels.  26" wheels are still usually pretty easy to find used and cheap... you might want to find/invest in some shorter cranks (Suntour offers a good cheaper option) than what come stock on any 27.5 bike you find... but now you'll have two bikes that your kid can grow into.  Did this for my son in 2019 and this season (2022) will probably be his last on this bike (his speed and performance is is also outgrowing the 120mm of rear travel), but this bike lasted a good 4 years on a quickly growing kid... hopefully bypassing the entire pandemic pricing and availability issues (we'll see how next year pans out).

Anglesets.. yes.  All four of our bikes have various anglesets... even mine, which is a 2022.

FS bikes for kids and when?  Touchy subject around here.  I got my kids on them pretty early, partly because I found fantastic deals on solid quality bikes I could work with for a number of years, that would retain value.  But also partly because during a situation where I rented bikes and my more timid reserved son started riding at mach 10... I saw the benefits.  And with my other son... I feel like, at the speed and performance level he was already at when I got him one... I felt safer.  And he definitely is using it to its full potential and beyond now.

Hardtail v. FS for a kid or adult really comes down to two things. Budget and Expectations. Like most stuff with parenting, it’s a personal decision, full stop. 

For example, I completely understand why, from a young age, my friends shuttling and ripping bike park with their kids spent the money on FS bikes. Most (most) of them were clued into the extra maintenance costs (suspension service) and the trade off in speed, safety, and terrain they could access was easily worth it. 

Personally, my goals and philosophies in introducing mountain biking (and other sports) to my kid differ quite a bit from most folks (other riders) I talk to about the subject and that’s okay. Optimized hardtails generally suite our family really well for the terrain we ride and have other benefits too.

Definitely! Writing about min-maxing & kids’ bike in a single piece is a (gin &) tonic for my soul. Two areas I’d love to see more coverage of on NSMB.

Sweet! Certainly don’t claim min-maxing (or any of the ways I measure value) as my invention, it’s just always on my mind, so I write about it.

A co-worker introduced me to the concept of amortizing my life in my mid-twenties (thanks Penelope!) and there’s been no looking back.

I love seeing tricked out bikes for younger folks... Growing up I would dream of riding a Stinky 2-4, which in my eyes anyways was one of the first decently capable FS bikes for kids. Now even chromag is making a kids rig! It is sad to see that his kid will outgrow it before they out-perform it. It is hard to envision anything else that would really need to be min-maxed here, aside from the usual angleset.

You can see the love that went into this paint job, that is so awesome. I like the comment about the M785 brakes hahahaha, they truly were a god send in the days of squealy avids.

On the subject of Avid brakes - with an exception given to the very first gen Juicy 7 systems (which were apparently made at Formula??!?) - I think the same has long been true as is true today. If everyone just rode Code’s most folks would be happy with them. I think I may even prefer the lever feel/action of the original Code over today’s brakes. 

As 2-piston brakes go, I think Shimano could go back to making the M785 (and a four piston version which is what that generation’s Zee was) and probably have happier overall customers? Add replaceable parts - like bladders - and away we go.

Never knew that about Juicy 7s and Formula! Have to agree with you there, from what it sounds like getting today's code's with the short levers would give most shimano diehards a comfortable lever feel, with adequate power and way more modulation. A friend of mine will be switching from his Zee's to codes in the future. No matter how perfect they are bled, they seem to have a squish that shimano's old 2 pistons never did. Even guides, I am shocked at how good they feel, though I am on the lighter side.

Shimano and replaceable parts... Recently took apart an old leaky M785 caliper to measure the seal... Just a square ring, a JIS size could work. Blown away that they won't sell replacements of this, though.

Not sure where I heard it first, but I don't think it was ever a secret. Pinkbike did a cool feature on the history of disc brakes and mountain biking in 2017. It's worth the read I think, here's the link if you're interested.

You can find aftermarket caliper piston and seal kits on the large marketplace everyone hates. I will vouch for them, however avoid the master cylinder piston kits. Those are wayyyyy inconsistent size wise. Nothing like a brake just pulling to the bar to make your tighties not so whitey.

Spare parts aside, I think the one difference I’d have made is to drill/cut for a stealth dropper. A OneUp would add a lot of drop here.

I do love this project all the same though!

"Auncle"? is that a Canadian thing? I'd probably only go for a hardtail or even rigid for them. I don't live close, so I'd just be giving my brother in law a headache trying to setup a fs.

Hi Andrew, I love the articles and the whole series! Thank you. I sent you an email a while back about my Kona Process 111 2015 that I have been min maxing the life out of! I hope you could take a look at it some time. Keep up the great work!

Cheers, Mat,

Those (actually second gen) 2014+ Process bikes are such min-max heavy hitters that I could have one up for every other min-max piece! 

There have been some sweet 111s - and that bike has a lot of talking points like the 1x specificity - so maybe I should do a couple of them in the same piece?!
