This ^. I would recommend one day at as many bike parks as possible vs multiple days at one place. Keystone, Steamboat, Trestle/Winter Park, Crested Butte, etc are all fun.

Probably not. He said himself it was the first flat tire he's had in a race. If he would have been running an extra 4 lbs of rotating weight at the tire for all of his World Cup races, he wouldn't have flatted at Leogang, but he also most likely wouldn't ... more »

Added reply in a thread why doesnt anyone use dual rate springs in mtb 6/26/2014 3:02 PM

On a coil sprung fork, yeah, it would make sense to have a progressively wound spring, which is common on motorcycles. It seems MTB forks are gravitating towards air springs, even for DH, though. Then, air volume can be adjusted for the same effect, ... more »

That's a leverage curve issue. Air shocks have had an overall similar spring curve shape for a long time. The frame should be designed around it, if it's designed to use an air sprung shock. You can make a frame with good small bump compliance that uses ... more »

That's the design philosophy that I used on the Guerrilla Gravity GG/DH, except I went one step further. No linkage, progressive leverage curve, standard coil shock.

Added reply in a thread why doesnt anyone use dual rate springs in mtb 6/26/2014 2:06 PM

Cars and trucks generally have a lot more limitations with packaging, and don't have the luxury to move the shock around to modify the leverage ratio curve (although they call it Motion Ratio or Installation Ratio in the automotive world) as much. Even ... more »

As much of a pain that pneumatic tires are, using air as a spring is very light weight, low rolling resistance and able to be tuned for stiffness (ie tire pressure). The "tweel" design will most likely always have higher rolling resistance and probably ... more »

The Guerrilla Gravity Megatrail already has that sort of change with Trail Mode and Gravity Mode. Geometry, travel and leverage curve all change by moving one bolt. Vital has already ridden it: http://www.vitalmtb.com/product/guide/Frames,7/Guerrilla-Gravity/2014-Megatrail,14284

Correct, medium cage length is required to handle the chain slack from the 31t spread (42-11). The B-screw setting is what determines whether the derailleur physically clears the BFC or not.

To all the size skeptics I say ride the bike. I originally thought the same thing that everyone is commenting about but after riding the bike. I'm 5'10" and will be buying a medium.

Size Large Stumpjumper: 24.5" ETT, plus what appears to be about 1.5" of offset at the seatpost and what appears to be a 70mm stem. Adding those extra lengths makes for a butt-handlebar length that's about 2" longer than the Small Megatrail.

It can make a difference, which is why we mention it. For example, one skeptical rider was questioning the length, as the frame itself was longer than his current rig. Then, after realizing he was running over an inch of offset at the seat post plus 20mm longer stem length, he agreed the MT package made more sense.
