World Cup Punctures and A New Face - 2020 Lousã DH World Cup

With the 2020 World Cup Downhill season coming to a close, some riders have been left thinking ‘what if?’ The racing in Lousã was incredible, with intense riding and epic battles on a great looking track. Conditions sounded tricky at times, with the loose dirt packing down and causing some problems, particularly in the upper portion of the track. Everyone seemed stoked regardless and the new track has instantly become a racer and fan favourite.

The big holes, sharp rocks and mix of slick and loose dirt, left riders puzzling with suspension setup. For some, including a few podium contenders, perfectly tuned suspension couldn’t help them. Here we are in 2020, riding these magic machines down the sides of mountains and something as simple as a flat tire can still ruin everything. With the galactic leap in technology that bikes have seen over the last two decades, it's no wonder the limits of our tires remain a sore spot.

The dreaded flat…

When I first started riding and racing 20 years ago, flat tires were the enemy. There were so many problems with the bikes and components; snapping forks and frames, cranks, bottom brackets, destroying wheels made from cheese, brakes that rarely delivered power during a full, short race run... The list goes on. But it was usually the dreaded “pssssss, ssss, sss, sss” that infuriated us most.

Michelin's Comp 16, 24 and 32 tires arriving between the tape improved reliability. They set the standard in the first years of the century until Maxxis began taking over. The popularity of Maxxis DH tires at the races only increased with the release of the DHF. Then, more recently, many of the teams sided with Schwalbe, particularly the Magic Mary. But the flats have continued throughout. Tubeless was another standard that helped but we all know that’s not a solution either.

Now we’re getting numb to riders stuffing their tires with foam to fend off flats. Many insert manufacturers claim all sorts of other benefits but we’re still seeing the same old thing happen; racers on a stormer succumbing to a flat tire. For Loris Vergier, a flat in the first race at Lousã marked the beginning of the end to what was shaping up as his first championship. And with so much of the sport riding on confidence, his flat could have played a role in his on track issues come race four, Sunday. It certainly played a role in losing the points needed to take the championship.

Young American rider Dakotah Norton has shown some brilliance on the race track in the last couple of seasons. At the final race in Lousã, Dak was looking strong, with a top 20 finish in his sights. That was until he blew his front tire in a berm. Once he got back on track, heading onto the flat pedal section, his right tire bead completely came off the wheel. Making it more spectacular was what appeared to be a Cushcore insert bundled away in his open front tire! Nevertheless, another potential result was ruined by tire problems. With Dak looking for a ride for 2021, the flat couldn't have happened at a worse time.

That’s just two of the riders during the live broadcasts that had tire issues. A few others include: Charlie Hatton of Continental/Atherton with a rear flat ’20 seconds into his final run,’ Brendog (Scott) and Mike Jones (MS Mondraker) with rear flats during the final, and French junior pinner Thibaut Daprela who flatted in his final qualifying race of the year. Luckily he was a protected rider because the 63rd place qualifying result would have put him out of Sunday's race.

It’s not clear exactly who was running tire inserts but watching the racers come down, it looked like at least some of them were. Loris, as talented as he is, seemed to have something to help hold his tire on the rim despite recent bike checks stating he doesn’t run inserts. One went as far as saying; "he's not running any inserts, due to the fact that they haven't had any problems with the Maxxis tire / Reserve rim combo that would lead them down that route.” Things didn’t work out so well in Lousã but the Syndicate, and other teams, have been sporting some “Test Pilot” Maxxis treads for a while now. There’s also the “Breaker” labelled treads that were first spotted back in 2018. Are these 'prototype' tires the reason Loris was able to ride reasonably well with a flat?

Inserts seem to help many of us but at the top of the sport, do they? It would be awesome to see no flat tires at all, but that’s probably a pipe dream.

The Positive – A New Name

Before this season, not many race fans outside of the U.K. will have heard of Jamie Edmondson. Despite being a junior on the Transition Bikes/Muc-Off team with Tahnée and Kaos Seagrave, the 19-year old flew mostly under the radar. It’s not uncommon to skim over all but the flashiest of juniors, focusing more on the names that are taking the limelight; the Finn Isles or Thibaut Daprelas of the junior ranks. But in his first season as an elite, 19-year old Edmondson has chalked up impressive results.

Jamie is a privateer who says he receives a little support from Nukeproof, Hunt wheels, Fasthouse, Maxxis, Fox and Chromag but still had to pay for much of his bike and certainly travel to the races this season after a less than stellar end to his junior racing.

For 2020, he mixed things up and decided to race some enduro, which he feels helped his fitness during the challenging doubleheader World Cups. But it’s one thing to race a few enduros – we hear many riders mention it – it's another to perform. Jamie went and secured podiums at all three EWS races this year, finishing in the bronze medal position of the highly competitive U21 category.

It’s great to see young privateers do so well and with his results at all four World Cups, Jamie secured 11th place in the overall, the top-ranked Brit behind new series champion Matt Walker. Some may say conditions played in Edmondson’s favour on Sunday but he’d already secured a 10th in the race on Friday, besting his 29th and 34th place finishes at Maribor.

Those are some amazing results no matter how you slice it. When chatting with representatives from Hunt wheels prior to Lousã, I learned they were already confident Jamie would be picked up in 2021. Now it’s almost certain we’ll be hearing Jamie's name as part of a team in the new year.

I don't think the answer is complicated- make everything heavier and thicker.  A dirt bike tire weighs 17lbs (7700g) or something ridiculous.  

2000g tire (yep- the weight sucks but it won't go flat)

650g rim with a smooth 10mm rounded edge on the top of the rim wall so you can't cut the tire.

Heavy wheel/tires are cool once you get them up to speed- heavy gyro effect keeps the bike stable and they seem to maintain momentum over chop better.

I wish tire companies made DH casing tires withOUT sticky rubber for the rear of my enduro bike.

I'd like to see more in this direction!

Fairclough said his flat at Lousa 2 was his first flat in 2 years on any bike.  Seems like the lighter weight is a worthwhile compromise if you flat once every few seasons.  But I'm all for having our cake and eating it too!

Wouldn't there be some serious issues with the ratio of sprung/unsprung weight? MTB suspension is already very tricky to get right, doubling unsprung weight might mess things up even more.

I've watched several folks do the slow ride of shame limping out of the trails wearing a soggy cushcore insert wrapped around them like a bandolier trying to keep the broken rim/trashed tire going long enough to make it to the car. I'm not knocking CC by saying that, but if normal trail riders can find the limit of inserts than it's not surprising that WC racers can.

Like most things in sport the technology exists to make it impossible to break something [frames/tires/rims/etc...] the question is does anyone want to accept the inevitable compromises that come with indestructability? It seems like in most cases the answer is no.

It’s a weight thing really. I’ve heard people complain that they need to change seals in forks annually yet their car doesn’t need that service. But if you ran seals as tight as those in a motor vehicle not even the fattest rider on an ebike would move them. Same with tires. It would require a lot of weight to make a tire and rim that would be unlikely to flat for DH racers. And that weight would not accelerate as well as a lighter weight bike. When you are racing time counts. A second slower from a start can be the difference between a podium and sixth place.

Agreed. If the majority went to a heavier tire and were able to absolutely smash shit in a run with zero concern of failure only to start consistently besting their competition, would more be accepting and then move across? 

What's the difference in weight from each top World Cup race bike? How much of a role do strength and rider size play? Tracks would certainly come into the equation too. So many questions!

I feel like there's some other construction changes that can happen too - I don't know why we're running so much sidewally height, especially as the shoulder area keeps getting new composite layers embedded in the tire construction, to me a lower profile tire would absolutely be the answer - yes we'd be looking at carcass-to-rim contact more often for comparable pressures, but practically that system can run at a higher pressure without unwanted contact patch changes as the tire distorts under load into turns.

Yeah, like all things bike it’s finding the right compromise. At some point weight or rolling resistance will cost more points through a season than one possible puncture.

For recreational riders, at some point more reliability will come at the cost of fun factor. Bikes are already trending toward faster, more comfortable, but less fun.

Depends. I find that over the last few years, the ratio of time spent on uphill vs. downhill has become even more lopsided than it used to be. Unless you shuttle all the time, but thats not what biking is about for me.

Bikes are getting heavier, tires are beefier, rubber is stickier, which makes uphills take longer. On the other hand, bikes are getting ever faster on the downhill and riders seem to take more inspiration from racing than from freeriding. So we end up spending more time on the "less fun" part and less time on the "more fun" part.

But maybe all that thinking is moot anyway if, in a couple of years, there will only be motorbikes and uphill is just a question of watts, newtonmeters and ampere-hours.
