Peddle strikes!

[Bojko]

Hi all, fairly new to emtb just brought cube stereo hybrid one77 and just keep getting constant peddle strikes! Messed about adjusting suspension/tyre psi etc, is there anything anyone else has done to combat this problem, read online it’s fairly low bb but just wondering what parts etc people have used thanks in advance -Jack

The "ride better" posts really annoy me.

I found I had the same reaction, perhaps we should qualify that seat of the pants reaction. If reddit posts and AI answers are correct, then:
1) when the rider remains upright (no lean), shortening crank arms by 10 mm provides exactly 10 mm more vertical ground clearance to the pedals on any bike. At about 1/3 of an inch, 10mm is not much when you consider that poplar tree roots can elongate 20-30mm per day.
2) Shortening mountain bike crank arms by 10 mm increases maximum cornering lean angle by approximately 3.7° before pedal strike, from 45° to 48.7°, by reducing the pedal's radial distance from the bottom bracket center (mountain bikers hit 25–40° on flat/dirt corners to engage side knobs without sliding). This gain in lean angle however only translates to a gain of .4mm before a pedal strike if the math I asked AI to do for me is correct.

I don't really care about maximum lean angle, I care about the increased clearance at all lean angles. This is especially important when I'm pedaling through a turn or starting to pedal out of a turn early.

I had a bog standard Rockshox Deluxe R rear shock, not a piggy back, almost impossible to set a consistent sag, and it suffered from static drag sticltion swapped it out for a Bomber Air rear and a night and day difference. Don't just presume crank length is the problem.
