Devinci Global Racing's Nick Beer was aboard a prototype 650B wheeled Wilson during last weekend's New Zealand National Championships, and his race run aboard the bike saw him place third, less than three seconds off of the winning time. Nick was understandably cautious about showing the bike off, wheeling it quickly out of sight when he wasn't up to speed on it, and the only look that we've had of it up until now were video screen grabs that revealed only a revised forward shock mount. There is more to be seen, though, as this photo from our man hiding in the bush clearly shows.
Nick Beer's prototype Wilson uses 650B wheels, as well as a different shock position, suspension detail, and is built out of aluminum.
The most obvious talking point, at least from looking at this photo, has to be the revised shock position that sees it attached to the rocker arm (
Devinci refers to this as the 'Control Link') with a short extension. The Control Link still rotates concentrically around the bottom bracket via two massive sealed bearings, just as on the current 26" wheeled Wilson Carbon, but it differs in shape slightly compared to what is found on the standard bike, and its unfinished appearance also alludes to the fact that the design is far from being locked down. ''
"This piece is really the heart of the stiffness of the chain stays, and also how the bike reacts to bumps", Dave Weagle, the bike's designer, explained to us when
we first debuted that Wilson Carbon in 2012, and we wouldn't be surprised to learn that different versions of the Control Link have been and will be tested during the off-season. The shape of the control link also determines the suspension's leverage ratio throughout its travel, as does the position of the forward shock mount. This is where the short extension connecting the Control Link and the shock comes into play, as it lets the shock be located where required, while also allowing for a short, stiff shape to the link that delivers the correct leverage.
The production Wilson Carbon, pictured above, features a different shock position, 26'' wheels, and sees the shock connected directly to the Control Link
The other detail to notice is the bike's aluminum construction, something that isn't a surprise given that Nick's machine is clearly still in the prototype stage and may see changes before Devinci invests in what it takes to build it out of carbon fiber. It's not just the front triangle that uses aluminum, though, with the swing arm also being made from the same material. This definitely hints at completely different geometry compared to the 26" wheeled bike, with the slightly larger wheels requiring a different set up numbers to see the bike handle well. It's also easy to spot the difference in the seat mast area, with Nick's bike featuring a completely different shape to it.
| We are always testing and developing bikes closely between our R&D department, test riders and DGR. Of the many bikes which are ridden and tested not all make it to production or see the showroom floor. Some of these bikes transform into other bikes, some are used to push limits. At this stage in the game we are working on lots of exciting projects which we hope see the light of day one day, as for the bike Nick was pictured with, this is a DGR development project and has no release date or production timeline. With the luxury of having the DGR racers we have, we are constantly experimenting with DH projects to help our riders rise above the competition. Of these projects most will never see production. - Gabe Fox, Marking Manager, Devinci |
Will we see the Devinci Global Racing team aboard the 650B wheeled bike during the 2014 World Cup season? We'd guess that is very likely, with both Smith and Beer putting in some pre-season testing aboard the bike before the series kicks off in Pietermaritzburg, South Africa, in early April.
29er fatbikes do exist, they're calling them 29plus. Surly krampus is the first one that comes to mind.
If you have a larger wheel and keep the BB height the same, it is lower relative to the axels and does not heighten the center of gravity. It actually is more stable, which is why 29ers are so stable at speed.
Most bikes were rigid and people said 2inch of travel was enough.
A year later gt came out with the sts dh with 100mm of travel and people thought it was excessive.
Now even kids bikes have disc brakes, trail bikes have 7 inches of travel and still pedal.
Dh bikes are long and low and have double the travel.
You cant buy a 4 or 6 inch travel dh bike these days.
Is that a problem? No because 8 inch dh bikes have evolved to be fast as hell, planted and still pedal when you need to smash some cranks in on the straights. Wheel size will be the same. When 650b is the smallest available and is faster, people will be amped because they are travelling faster. The speed will translate to fun and people will just accept it like all the other stuff they scoffed at
If it was marketing, would the defending WC champion move to a wheel-size that was slower? It's not like he had a huge lead over 2nd place where he could afford a disadvantage?
The next thing I am waiting to hear is 650b is wrong because it's not in the Bible.
@ ctd07 - why don't you try that experiment again, with the same tire. not exactly science your doing over there...
Why don't all performance cars use the same size wheels?
things that make you go hmmmm...
What does "the difference at which the tire hits the ground is only 1/4 greater" mean?
What exactly are you measuring?
I owned a 24/26 Big Hit DH back in the day. I often got the sensation of the 24" wheel maxing out at terminal velocity, like it just couldn't go any faster. It was a weird feeling I never got on dual 26" DH bikes. Mind you, this was only on open fireroad sections of the bike park and didn't really come up when riding trails/jumps/berms/features.
I've got a 650b DH bike on the way so we'll see what happens. It might be that 26/650b is the perfect combination.
Try out only doing it missionary style, and see how you like it.
I ride MY bike for me.
Makes sense if you are a big guy and have an xl or xxl frame to have 29er.
24" mtb wheels please! SO FUN and looks good. Every bump is fun.
