Rusevelt Posted June 1, 2011 Report Share Posted June 1, 2011 Xpedo pedal, uses an Elastomer on the pedal axle to suck up the bumps on rough terrain. http://www.imbikemag.com/forum/showthread.php?206-Interbike-Xpedo Quote Link to comment Share on other sites More sharing options...
monkeyseemonkeydo Posted June 1, 2011 Report Share Posted June 1, 2011 Not convinced that would do anything at all... Most of your weight should be centred over the axle and that is still rigid. If your foot is flexing round the axle then you will be putting pressure on both the front and rear of the pedal body and due to the scissor type design that would virtually negate any 'suspension' effect as well wouldn't it? Combined with those square extrusions which look like they limit 'travel' to a few mm, it just all seems wrong! Quote Link to comment Share on other sites More sharing options...
Tomm Posted June 1, 2011 Report Share Posted June 1, 2011 Apparently the idea is not that they will provide meaningful suspension, just that they may stop your feet from jumping off the pedals. I doubt it'll work, though. Quote Link to comment Share on other sites More sharing options...
Rusevelt Posted June 2, 2011 Author Report Share Posted June 2, 2011 Didn't Leeson bikes develop a frame called the 'Bump' which used an elastomer in the headtube for the same purpose to absorb the bump forces from doing taps, and hooks?

monkeyseemonkeydo Posted June 2, 2011 Report Share Posted June 2, 2011 Yup, it's still doing the rounds on the forum as well. Last seen in NMC a couple of months back if memory serves me correctly... Quote Link to comment Share on other sites More sharing options...

mr kenny Posted June 2, 2011 Report Share Posted June 2, 2011 (edited) NOt to sure these will work to well, even to take the shock/ bumps/ vibration out of the ride. what stops them just being at 'full' travel when you stand on them and during your pedal stroke these will change the height of the pedal - all be it 5 mm but this will still feel like a bent bb/ pedal axles. Thay atre pretty though Edited June 2, 2011 by mr kenny Quote Link to comment Share on other sites More sharing options...
Rusevelt Posted June 2, 2011 Author Report Share Posted June 2, 2011 They probably just provide a noticeable cushioning effect that you can feel from the bump/vibration forces travelling through the pedal axle to your feet and legs, rather than behave like an active coil/air shock suspension. So ideal when riding along a cobbled path or road which make your feet dance about on the pedals. Quote Link to comment Share on other sites More sharing options...
