XC Bike Checks: 4 World Cup Race Machines

May 24, 2014
by Matthew DeLorme  
Nove Mesto is the first standalone XC World Cup of the season. We took a stroll through the pits and found some interesting new goodies, namely from Shimano and in the form of the Rock Shox RS1. Nove Nesto lacks some of the super technical terrain of PMB and Cairns, and the track has plenty of roots and soft loamy dirt off the main lines. Most of the field is opting for the hardtail this weekend, with a few dual suspension hold outs for the rock gardens.

Kulhavy s S-Works Epic. This bike is set-up pretty close to stock. Note the mega steep seat angle and low front end.

So far Kulhavy is the only one pushing a 38 tooth ring up front. While there isn t a ton of elevation here in Nove Mesto the course does pack in a fair amount of climbing. That could change by Sunday but for now 38 it is.

 I think how purpose-built these rigs are is as interesting as a WC DH race bike. No compromise for the intended purpose.

 Agreed. I love the fact that progression and refinement happens everywhere in riding. The power required to push a 38t ring around a course in a race situation is scary!

 its great to see Pinkbike showing these XC bikes as all bikes are great, whatever you are actually into yourself!

I spent years racing BMX and DH, and then Freeride, I don't do that anymore but am still interested in seeing all kinds of bikes;- road, cross country, bmx, downhill, etc.

 That seat angle though
  • 15 16
 It actually makes some sense given how steeply angled the stem is.
  • 63 29
 No it doesn't.
  • 114 3
 I think it's meant to be super uncomfortable, to make you want to get off the bike ASAP, leading to a faster finish time. That's my theory anyhow.
  • 28 2
 It's angled down like that to put the rider in a stronger and more comfortable climbing position. That's also why the stem is so low, as when the front axle is higher than the rear, the riding position on the bike returns to neutral. Pick the front wheel up a few degrees and all of a sudden the seat is level and in a strong and comfortable position for seated climbing and steep grades. Also makes it much more comfortable when moving forward towards the nose of the saddle. That's the logic anyway, but this does look like a crazy exaggeratedly steep angle that goes outside of the conventional nose-down for climbing line of thought.

 I know someone who was using a negative 33 degree stem and his seat angle was still the same
  • 2 0
 Yeah I though it actually looks cool until I saw the seat
  • 2 0
 I run my seat quite steep as well, although not as steep as this. I feel it makes pedalling a bit more efficient with not as much energy lost in wandering over the seat. Quite personal though, as these photos show, they all know what they're doing but have their own setups. That said I can't imagine Kulhavy's bike being that comfy when riding longer distances in the saddle.
  • 11 0
 Come on folks, where are you sit bones? Are they in your balls? No, they are in your ass, way back there. When you ride with the nose even slightly pointed up, your perineal nerve gets all the weight. The larger the difference between the saddle and your bars, the more your bent over, the lower the nose needs to be. On a downhill bike or BMX bike, where the seat is below the bars, it's the opposite.
  • 2 0
 It allows you to rotate your hip far better and much less lower back pain in racing attack position... i know cause i had same pain / problem...
Also less risk of infertilitie...
The opposite side of sadle like this is your arm triceps gets much more tension all time cause all your wheight is forward to the handlebars...
  • 3 0
 Same strategy Specialized has with fitting a time-trial bike- if you rotate the rider forward and lower, you should adjust the seat angle to match the drop distance. It's science.
  • 3 1
 @srbdude1 One person in all of professional racing runs their seat at a crazy downward angle like that, and it's the way to go based on results? Have you adjusted your saddle to a 30 degree downslope? How much faster did you become?
  • 2 0
 I'm not a world class XC racer and have much shorter legs so it wouldn't work for me. He wins quite often so I wouldn't question his setup. How you ride and what you ride is irrelevant to Yari.
  • 2 0
 An ideal seat angle is all relative to the application, but there are a few misconceptions. To a certain point, angling the nose down can place more weight on your nerve, as the slope rotates your hips forward and forces you towards the front of the saddle, both of which place more pressure on your perreneal nerve and your wrists. Your seat angle should support your sit bones and allow you to sit unsupported by your arms while placing a minimum amount of pressure on your nerve. It's a delicate balance, and is all relative to the application and terrain. Time trialists are resting their upper bodies on aero bars and need to be forward with a perch to sit on and push back against for a ton of power in a very very low and awkward position. If their seat was flat, and their bodies were in that aero position they would squash their balls and be pushing themselves off the back of the saddle. Totally different than Anything being done on an mtb. In mtb it's for climbing and maintaining a low attack position, and still mostly comes down to rider preference. On mtb for trail riding I generally prefer level to slightly nose up depending on the saddle and intention on the bike, which usually has a bias towards descending.
  • 2 1
 I've always run a steep angle like that and have always copped shit for it. Whether it is cross country, DH or freeriding it saves my balls getting sqeezed, smashed and chafed. Nice to see a pro who doesn't want testicular cancer.
  • 3 0
 So riding with a level seat = testicular cancer? Thanks for the advice Dr. choppertank3e!
  • 3 0
 With that much drop distance between the seat and handlebar position, riding with a level seat generally places more pressure on "sensitive tissue", not just balls. That pressure reduces blood flow which can lead to a number of short term (i.e. riding discomfort) and long term problems (i.e. numbness, etc). Depending on the person, saddle choice, short/bib choice, lowering the nose of the saddle in relation to how much drop exists between the saddle and the handle bar is generally a really smart, comfortable, and efficient move.

 Pinkbike: where the haters come to hate.

 Its so he can use less upper body muscles (waste) to hold himself on the bike while climbing, just a more efficient position. With that said I still think it looks kinda silly

  • 1 0
 ^ Would be awesome.
  • 1 1
 It'd also be cool if you could have a lever adjust fork height that didn't adjust your fork travel length (like a dropper post for the front end of your bike).
  • 1 1
 Think about that a second. How's that supposed to work?
  • 2 1
 by the amount of stanchion showing on the fork. done by raising the 'floor' inside the fork, not the ceiling.
  • 1 1
 But if your fork is 150mm travel, and there's 150mm stanchion showing, how can you reduce the amount of stanchion showing without reducing the travel?
  • 1 1
 I can't tell if you are trolling or just stupid at this point. Haven't you ever seen a u-turn fork?
  • 2 0
 No need for name calling. U-turn CHANGES THE AMOUNT OF TRAVEL.
  • 1 1
 I give up.
  • 1 0
 No, I'm actually interested how you plan to make a fork with (X) amount of travel that can lower the axle to crown without reducing the travel. Please, do explain.
  • 1 0
 What I'm saying is that companies with big R&D budgets pay engineers to work day in day out on how to minimize the a2c for a fork with a given amount of travel, and they will gleefully announce in press releases that they've finally managed to reduce it by 4mm. You think there's somehow a way to pull an extra 3-4 inches of drop from... where exactly without reducing the travel?? Come on man. Why would you even want to do that? If you're pedaling up a hill so steep that you need to drop the front end, why in the world would you need full travel?
  • 1 0
 You are thinking about it wrong. If you have an xc bike with 80mm of travel and a low front end like that epic at the beginning, it'd be cool to prop that front end up on downhills. And you wouldn't want the fork to be able to dive 140mm, only 80mm. So its not making a fork travel longer. It'd be pushing the lowers away from the uppers with a u-turn like system, which is done by turning the fork's coil. Instead of using the forks coil, you'd want a solid coil that couldn't compress. So its essentially like unscrewing a screw, where the crown sits on the head of the screw, or where the bottom of the lowers sits on the head of the screw, depending if you want it to be inverted or not.
  • 1 0
 Not worth the added weight. Fork and Shock lockout are most important with all else just adding a weight penalty.
  • 1 1
 You never know. Its just an idea anyways. Maybe it'd be more appropriate than lockout for an xc race. Do they actually use lockout while racing? I'm gonna ask Emily Batty on her article.
  • 1 0
 Yes they do. Climbing and flats most run lockout.
  • 1 1
 Dunno about reducing but I increased my forks axle to crown without increasing the travel. You could do the inverse. However you would have to have a relatively high axle to crown distance to begin with which no one wants.
  • 1 1
 I'm talking about increasing, like you did, not reducing. Why would you reduce an already extremely low axle height for downhills?
  • 1 0

 If there was an advantage they would use them, they can make up more time climbing faster than descending faster.

 Use a Hite-Rite. Much lighter than a dropper. Had one through the 80's. Grease yer post and zip tie a section of inner tube over the insert section to keep it clean. Hell, leaving the seat QR open, it was consider "suspension"! Ha ha.
That one goes out to the old folks. Har har har!

 Keep in mind the mental prowess it takes to operate a dropper post when you're gassed - I guarantee you can't. These guys are going 120%, they can't be bothered trying to fuss with a silly dropper. Also, these guys are so skilled at riding tech / descending with a high seat that operating the dropper is still a disadvantage, when compared to riding their descent and immediately powering out.

Give it time though, it'll happen

  • 8 1
 XC racers occasionally use dropper posts, especially taller or oddly proportioned riders; Todd Wells is a good example. I think part of the reason that they aren't prevalent is that on an XC bike, with a steep seat tube angle, it's relatively easy to get behind and out of the way of the saddle while keeping it at a good climbing height. I ride a lot of XC and I rarely have trouble descending technical terrain.

 One high performance bike tire is just as hand made as the next. The big difference between tubulars like these and a beaded tire is that the tubular has it's tread glued on to the sewn shut carcass with inner tube enclosed and a beaded tire has it's tread and open carcass vulcanized together into one peice. Otherwise they use similar production techniques, and in both cases lots of hands touch a tire to make it.

...and when the carbon wheel is ready to run the aluminium wheel instantly starts to suck. Aren't carbon rims usually considered more shock absorbing anyway? On top of that, he's raving about having this stiff ass fork and then ruining its benefits with a flexy wheel. Wut?

Cool bikes nonetheless Smile

 Made no sense here either. carbon rims are so much better on the ragged edge- besides, no bike here seems to have any soft spots... Would be neat to see an inverted fork on the podium though.

 He is a world cup racer and they say he doesn't have a carbon wheel because they don't produce them yet... When have WC racers had to wait for production?
Couldn't they have just laced a carbon rim onto an rs1 hub? Seems like a big oversight

 I thought carbon wheels were stiffer and have read that they rode harsher.

 I would like to merely point out an interesting fact about geometry. Look at seat angles of those bikes, they are quite slack by "Enduro" standards, where people claim they need 74-75 degrees. Worlds like "it's physics", "it's efficient" pop up in internet discussions, well... think again, who else than XC racers can need more efficiency on uphills? My point is, don't put so much trust in numbers, put lots of it into mobility of your body.

 Seat angle =/ seat tube angle.

 that is because even the FS bikes don't run any sag.

add 2" of sag on a 6" enduro bike and you need a much steeper seat tube when a rider is actually on it.
  • 3 0
 Off course they run SAG, what? There is only one bike that runs no sag, it is called rigid bike and the reason why xc race bikes do run sag (even if it is 15-20% is because suspension makes them more efficient when riding and pedalling through rough terrain. For dead flat sections those guys use lock out.
  • 1 0
 lol yah. I run about 10% sag on my Spark 29.
  • 1 0
 Full suspension World Cup xc bikes run sag equiv to about 5-8mm at the wheel. 5-10%.

Enduro bikes are more like 30%, or 50mm at the wheel.

Do the math. Xc bikes need about 2-3deg slacker seat tubes to be in the same place relative to the bottom bracket. Or, long travel trail bikes need a 2-3deg steeper seat tube compared to an xc bike.
  • 1 0
 The sag doesn't apply to the front as well?

 marshalolson - when you sag a full suspension bike with quite equal amount of travel front and rear, the bike angles stay more or less the same Blank Stare There is no relation in that subject between XC bike and Enduro bike.I am not saying steeper seat angles are bad, no they work better as long as you have an adjustable seat post, or you live in the mountains. It is very hard to ride a 75 deg seat angle with seat up. Then Xc bikes use slacker seat angles because they need room in the cockpit while pedalling seated, their frame reach is short to provide as short wheelbase as possible. Uphill handling is the key, no xc race is won on downhills even though many are lost there.
  • 1 0
 a pro xc bike sees around 10% fork sag along with 10% frame sag. a trail/all mountain bike sees ~15-20% fork sag and ~30% frame sag. you are comparing apples and oranges. there is much more bias toward rear wheel weighting on a trail bike vs. an xc bike, so the seat angle at static needs to accommodate this.

xc bikes run more offset in the seatpost to gain watts when mated to long stems, low/narrow bars etc. it gives leverage at different places in the circle.
  • 1 0
 Sag shmag, 20% front to 30% rear on a 7" frame with 7" fork means a difference of 10% means roughly 15-20mm bias which equals barely a full degree, equaling seat position going roughly an inch backwards. I can off course check your theory in a CAD program but to me there is no water in it. You further mention offset posts which proves my point more because that slackens the effective seat angle even more. I am open for suggestions and I like people disagreeing with me
  • 1 0
 Just to clarify: my original point was that steepening the seat angle from previous am dogma being 72ish to nu school 75ish has next to nothing to do with pedalling efficiency.

 Nino must like running a higher cadence than the other riders seeing that he is on a 27.5 wheel and running a 36t ring. That would be like a 34t on a 29er, much smaller than the other racers run. I guess the higher cadence works...
  • 4 0
 Higher cadence does work, less effort per revolution of the crank, thats why you see roadies pedal at 90+rpm
  • 1 0
 Depends on the rider, although I don't think Nino has a higher cadence in particular, as I think a 38t ring is overkill, you're not gonna spin that out on that course, so why not have a lighter ring with better clearance.

Also, although a higher cadence is generally more efficient (up to a point), a lower cadence works much better for some riders. Using the road example, Tony Martin goes at about 75rpm through most of a 25 mile TT; and when some of the specialist climbers like Contador climb, they sort of stand up and bounce, with a relatively low cadence.

 that is not something new, specialized has had for years full suspension bikes with BRAIN modded shocks, that basicly act as a filter that allows the shock to absorb impacts coming from the terrain and locks the shoc when climbing & bobbing. I've seen it being implemented in forks for a couple of years at least.

 @SocalMTB98 I didn't say they should race with 150mm you came up with that on your own buddy. You were talking about how awesome xc is and how painful it also is which i mentioned could have something to do with your body taking all the hits because you're on a hardtail and your butt hole getting raped by your seat.
  • 1 0
 Haha i race XC and i have a carbon 29er hardtail and at first it was bumpy as hell and hated it but after a couple rides, i started using my legs as suspension. Plus hardtails have a different feel compared to full sus bikes, they feel more attached to the ground and they are fun to throw around. And no your ass doesnt get raped haha, your not sitting on your seat through rough terrain, you either hover over your saddle or stand up. Dont talk crap before you try it.
