[Closed] 650b Pedal Catching

good job it's not a 26", else you'd be having an even bigger problem...

It's the trails coming alive and nipping at your heels as you shred them.

See,with riding 29er wheels I never catch my pedals (I do occasionally suffer altitude sickness though).

Maybe try looking ahead and pedal to avoid rocks. Try freewheeling over the high bits.
Or chose a better line.

Sensible answer - that'll be due to the frame design, not the wheel size. Lower BB to reduce the centre of gravity. Given time, either you'll adjust your style a bit to compensate or you'll get used to whaming your pedals on stuff. I used to have a Commencal Super 4 with the same issue.

(plus another rather larger issue that meant I didn't have to worry about it for longer than a year. 😀 )

Spoilsport!!!!!

Are running with a lot of sag ?
(I catch the pedals on my tranceX (26") quite a lot. I just view it as a consequence of a nice lowish BB that makes the trails [s]literally come alive[/s] acceptable for such a redundant wheelsize

its happened a couple of times on my 650beast, but no more than it did on my previous 26er, BB heights are roughly the same

All about frame geo and suspension settings rather than wheel size...

EDIT I may be wrong but I think frame designers are preferring a low BB as it gives a nicer planted feel because of the lower CG.

A low BB will obviously always handle way better. Downside is pedal strike, so maybe adjust your technique. I prefer low BB's.

I used to have a Whyte 46 which was like riding on stilts it was that high. It was great for rocky, technical, pedally trails though. I then had a go on a Pitch which was loads better - more planted - going downhill but I had loads of pedal strikes.

<end of pointless anecdote>

are you on flats too, as they are wider and therefore touch down earlier on corners

Of course, what you need is 650b specific cranks arms, and 650b specific pedals.

An article tackling this subject from a few weeks ago: http://www.bikemag.com/friday-five/friday-five-pedal/

Hmmm, its the same crank set that I had on my 26" which is why its weird! Thanks for the come backs though guys!

Got SPD's with a cage, again same pedals that I had on my 26" mach5.7 Carbon

Matt, it isn't weird at all! Your bottom bracket is closer to the ground on your new frame because it has more than 12.5mm extra BB drop (27.5ers need 12.5mm more BB drop to have the same BB height as 26ers, just like 29ers need 31.5mm more BB drop to have the same BB height) versus your old frame.

The BB height is very low on my new full-sus and I'm thinking about raising it a bit using the adjustable dropouts (it's currently in the lowest position). Most bikes don't have that tweakability though, so it comes down to sorting out your pedalling and pedal position when cornering etc and maybe running bigger tyres or less sag.

Just checked the Pivot website and the mach 6 does have a slightly lower BB if you were running 150mm forks on the 5.7

It's because your suspension is blowing through all its travel. Only Pikes can solve this.

Possible blowing through the mid stroke issue? 😉
