Grounding out

Postby dogthomson » Thu May 24, 2007 11:49 am

I repeatedly seem to 'ground out' (as in pedals digging into the dirt) when out riding, what could I do to avoid this?

Is it my technique or are 170mm cranks needed or what? I ride an '06 Mongoose Tyax Super, does anyone know if it has a notoriously low BB height?

Higher volume tyres may help. I think that many bikes ground out every now and again, some are worse than others.

Gonna measure the BB height when I get in. Honestly I don't know what it is it happens loads! I do ride a lot of trails where there is almost a trail 'cut out' of the dirt (if you know what I mean!?) and the slightest change of direction and *thud* I'm on my face!

Any tips on improving technique?!

I posted a similar question a few months ago. Trails full of rutts. Tailor-made by the Forestry Comission to be 1cm narrower than the width of my pedals ;-)
Technique is cr@p - but improving.
However, my spech has a low BB. And I was running 1.95 trailrakers at the time. Fitting my olde 2.2 enduros has made a noticable height difference.

prob more down to technique if it's when you're cornering or riding ruts.
