Lots of tech in the XC pits. Nino Schurter's Scott Spark is one of the few dual-suspension machines here. Schurter runs 27.5-inch wheels with handmade tubular tires by Andre Dugast. The absence of technological and weight restrictions means that mountain bike racing, not road racing, is the Formula One of cycling.
Pencil thin carbon seat stays - some say Nino's Scott weighs in the low 19-pound range.
I would have to disagree about the road bikes. although the UCI rules are ridiculously strict, technology will always advance. rules change eventually and even if they don't and the sport is the same tech will still get better. think of tennis, racquets they used 30 years ago are not the same as now
I follow road bike tech as well and it would be foolish to think that road bikes aren't pushing the limits of what the materials can handle. Trek and Merida (and many others) are releasing bikes in the sub 10.5 lb range.
the latest trend in road bikes is to make all components as aerodynamic as possible, which involves some pretty substantial R & D.
Low bars are better for climbing but they also put the rider in a more aero position which over 1.5 hours, will shave lots of time.
I think this bike looks f***ing dope! I enjoy all types of biking, and there really is nothing like a properly sorted XC rocketship. What blows my mind is that this bike is only a pound heavier than my Madone 5.2 :O
yeah you and me both! the lightest mountain bike I've ridden is my 2001 Schwin Homegrown Pro at 22 pounds, and at that weight it can scamper up some crazy climbs, but I need to true the wheels after each ride :/ I'm sure this is waaaaaaay better in pretty much every way!
I ride XC and would never consider a dropper. Do what you like. The 19lb mark is likely due to the carbon DT Fork and the rim/tire combo. DT doesn't even list a tubular 27.5 wheelset, just 26 and 29. I also think that the fork is a prototype and not for sale. Race rig in the extreme.
As well the stock Scott RC bikes are 21.8lbs out of the box or so and that is with carbon clincher wheels. Most of the weight savings likely comes from the tubular wheel/tire setup. 2.8lbs is a lot to lose when you are down at 21.8lbs. Layup on the frame could also be "race only" for Nino.
Did R.C. really basically say F1 racing has no restrictions? Who is this guy? F1 racing is a lot closer as Nascar, IRC, motogp etc to road bike racing with restrictions then wc xc mtb ing. Wow. I'm impressed. Great journalism. Luckily more impressed with Nino's bike. That is insane...especially tubular tires!
Dirty Knobbies, your point is taken and accurate in one sense. There are restrictions, however, for nearly all forms of racing (the ultimate land speed record may have the fewest.) Restrictions, however, can cultivate innovation or quench it. F1 is a formula - outside the formula, absolutely anything goes. The restrictions for road racing are basically, the bike has to operate, look, and perform similar to steel, diamond frame bikes like the Binachi Fausto Coppi won the World Championships upon in 1953. Cross-country racing bikes have a formula - a few wheel sizes, pedal powered, no motors, some safety stuff, but after that, anything goes. F1 got to where it is now because constructors were given that freedom. Not slapped down every time some designer got crazy, as road bike designers have contiuously been. Road bikes have evolved, but nowhere near the pace that they could have. Check your history and you may agree that, from 1980 to present, both the mountain bike and F1 have enjoyed a stratospheric period of evolution. Remove Triathlon, and the road bike is a carbon fiber model T.
What I don't understand is why there are no weight restrictions in mtb. I remember JHK showed off his xc race bike in bicycling magazine and he was running road rims on his 29er and three bolts on his rotors. Surely that is toying with safety just as much as ultra light road bikes.
There is no weight restriction, because you can not get away with a joke of bike. It will disintegrate. On road, reasoned chance to get away with stupid and too many people will be willing to risk it.
pretty sure they're new SKF ones: www.dtswiss.com/SKF-seal they're for sale, I'm about to pick up a pair for my DT swiss fork. edit: they're black in that link, but the greenish color where I've seen them for sale.
Nice! I'll be visiting Scott in a few weeks. I am "Schure" that they will be giving me hell for that. It's funny that nobody here at PB caught that when we went over the story. We always double check names.
haha yeah. Its flexy af on my skinny ass, so id bet this frame is actually lighter and has custom made stays for stiffness! And btw i saw this by chance; you have to use @ to make it pop up on ppls dashboards!
Yeah, I don't get it either but I'm sure there's been lots of experimentation and they came to the conclusion for valid reasons. Maybe it's that the speed on the descents is traction-limited by the tires already and there's not as much time to be gained as we would think?
The main motivation most XC guys I know seem to have to for it, is they think it somehow proves they're better than other riders. "I don't need that stupid drooper crap!" XC is weird that way, it seems to be an awful lot about proving how much better you are than other people, rather than enjoying riding your bike.
Well first off, Nino descends like a motherf*cker anyway. But also I think KS is the only company making an XC dropper right now (carbon, short travel), and it's probably not on everyone's radar. But I think we'll start seeing some hardtail riders use them. Pretty sure some women used them last year in the world champs? Doubt we'll see much FS with droppers though.
But I think there's some truth to the riders resting on the downhills. From doing xc races myself... It's f*cking scary to descend at full speed when your heart and lungs are that maxed out going into it.
And no dropper is for weight saving. XC guys will never add a heavier component unless there is a clear cut, measurable improvement in overall speed or reliability. Sure it's a small amount of weight on its own but when you apply the same logic to the entire bike build you end up with quite significant reductions over what it could weigh if you were a little less ruthless.
@kdstones, No1 - don't take stuff out of the context. This was a one bloody rock, I'd hit it myself without a dropper and I'm sure you would too. The issue is not about how hard you can go without a dropper, it's about why not use an obvious advantage giving you seconds for free? If you win a quarter of a second on every corner on descents, a second or two on every tricky section, improve regeneration after uphill by riding descents more relaxed, then those things add up during the course of the whole race and create some good advantage. There is no questioning what so ever that saddle lowered by 10cm improves all aspects of bike handling. Saying that Nino could ride most of Val Di Sole DH track on his XC bike without a dropper is probably true, but it's like saying that Nino could lap me on XC race on Dual Ply Minions in Slow Reezay while I would ride his regular bike. Sure he caaaan, but why go there?
I tell you what, If Rockshox and Fox, each made a dropper post, lighter by 50g than Reverb or DOSS, and then (this is the important part) they would market it as "XC specific", almost all those riders would be running one. Shimano could easily make a Di2 shifter for Fox, that is coupled with suspension lock out(s). It would sell like donuts on Police memorial.
Yeah let's not get too heated over a seat post here. I personally prefer a dropper, but I was just making a small point there. I think it's time we stop telling the pros how to run their own bikes!
I have always said, the stronger and faster you get, the heavier the bike you should have to ride. That being said, the Pros should ride bikes that are no lighter than 26 pounds and beginners should be riding 20 pound bikes.

No dropper. Still steeper than anything I would ever hit!
