Transition Launches the All-New Spire

Date Jun 3, 2021

Take on the biggest terrain without the penalty, long travel doesn’t have to mean single purpose. The Spire blends DH bike capability with mid-travel efficiency in such a way it’s almost two bikes in one. A delicately tuned pedaling and pumping platform, super supple beginning stroke sensitivity and all the travel you could ask for makes for a mind bending ride. Happily climb up to your favorite challenging descent, then cruise on over to your local flow trail and you’ll be rewarded on both ends of the spectrum. Don’t be fooled though, while it's no one-trick pony the Spire lives to push your limits.

Get in-Spired.

Spire complete bikes come equipped with suspension from Fox, RockShox or Marzocchi to take the biggest of hits. Powerful four piston brakes with big rotors front and rear help keep you in control. Schwalbe Magic Mary and Big Betty Super Trail tires offer you great cornering traction and braking performance in a variety of conditions. All build levels and sizes include 165mm cranks, a OneUp dropper post and a OneUp bash guide to ensure nothing holds you back.

The Spire is available in both carbon and alloy options. The Spire carbon features a full carbon frame made from premium Japanese Toray fiber with a tailored blend of 24T and 30T materials to create the right balance of frame stiffness, strength, and impact toughness. Our unique latex coated EPS molding process allows for sharper frame lines and tighter edge radius control with maximum strength to weight ratio and less wasted material. The Spire alloy features a frame made from tough and dependable 6061 aluminum to strike the right balance of frame strength, durability and ride quality.

All frames see protection on downtube, chainstay and seatstay. SM, MD and LG sizes share 446mm chainstay lengths and XL and XXL share 452mm chainstay lengths. All frames are equipped with a geo adjust chip at the lower shock mount for high and low geometry settings, and 56mm/56mm press in headset cups that are compatible with reach adjust headsets when used with a dual crown fork. All frames are compatible with 27.5 rear wheels in the high geo adjust position.

With nearly 23% progression and the most current evolution of our GiddyUp suspension kinematic, the Spire has an excellent balance of support and small bump sensitivity. Anti-squat is tuned to enhance pedaling performance and provides a platform to push against when pumping, without sacrificing a bottomless feel when needed.

The GiddyUp suspension layout is tuned to work correctly with both air and coil rear shocks. Riders are able to add or remove volume spacers in the rear air shock to suit their individual riding style and there is plenty of bottom out control with air or coil shocks when things get rowdy. The Spire has 170mm of rear wheel travel when used with the supplied 205mm x 65mm stroke shock. It is also possible to install a shorter, 205mm x 60mm stroke shock to decrease the rear wheel travel to 160mm if you are after a shorter travel experience.

A suggested sag range of 27 - 33% allows the rider to tune the feel of the bike; from a firm and snappy jump and slash mode, to a more supple and active full on party mode. Wherever you end up, you can focus on the trail without remotes, levers or knobs. Just grab your bike and GiddyUp.

Finally a proper XXL, and in carbon! Good job!

This is looking mighty similar to the new Patrol that just dropped...  Tiny bit longer and slacker, and not a dedicated mullet.  But still way closer than I'd have expected.  Cool bike but I wonder how they differentiate the two?

We'll aim to find out. Pete has a large Patrol coming and I have an XL Spire on the way. I'm pretty stoked to ride something that fits from a major brand.

Actually, AJ, I'm testing a XL Patrol and you'll be on a Spire in XXL ;)

Big boy! 😀

Going to be keen to see how it compares to your G1, AJ. Geo sheet looks amazingly similar between the XXL Spire and Extra Longest G1. Reach, chainstay length, HTA, stack all nearly identical. Certainly way more adjustability with the G1, which is rad. 

As a 6'6" rider, these are my two top choices to replace my XL Ripmo AF, but the local shop I like to support has the Spire on order so hmm...

These two announcements coming in short order actually have me excited about the potential of a revamped Scout.  I LOVE the straight headtube that allows for reach/angle adjust headsets, longer (but not crazy long) reach, slacker geo, and mullets.  I didn't have any plans to replace my trail bike anytime soon but a newly updated Scout could potentially tempt me...


Gage Wright  - June 3, 2021, 12:04 p.m.

At this point why have the sentinel in the line up?

Pete Roggeman  - June 3, 2021, 12:27 p.m.

There's enough of a travel difference between Sentinel and these two that it makes sense, Gage. I love the Sentinel and have it set up 150 rear/160 front (it can accommodate 170 up front) and it handles the steeps fairly well, but not as well as my Enduro at 170mm front and back. Doesn't seem like a big difference, but it is - and what doesn't translate onto spec sheets are shock rates. So, don't fall into the trap of only looking at the numbers (even though in this case, the numbers do help tell the story). I say that before riding the Patrol that's coming soon, so I'll have more thoughts after that.

This is one of the first bike releases in a while where I legitimately would have trouble choosing between the two colourways. The Patrol is pretty much the same but I give the nod to the raw. In this case - man, those are both beauties.

Look at the pricing of that alloy XT. A good $1500 less than a very similarly spec'd Chilcotin. Love that the alloy Spire has same spec as the Carbon.

And that purple, OMG.

As a Shimano/Fox guy, the XT spec is just bang on... was one of the things that convinced me to put a deposit on a Patrol XT :).

From a purely aesthetics point of view - Transition are killing it right now. That purple Spire has to be the best looking bike ever made. The killer spec and geometry don't hurt either.
