XC Geometry Question

So after about four years of being out of the sport I recently purchased an XC hardtail bike, and I have a simple question.

After I put a few miles on it I began to notice that at slow speed manuvering the front wheel strikes my shoes in the pedals level position and restricts wheet turn quite a bit. Obviously this is not a concern at higher speeds, but at low speeds where you have a fairly decent amount of wheel turn they hit. I was initially riding the Shimano M520 Clipless pedals with regular shoes to get used to the bike thinking that when I pulled the plastic platforms off and clipped in this would change, however it didn't.

Is this common for smaller frames (it's a 16" frame)? (This was definitely not an issue with my previous MTB)

Yes it would be the small frame, the larger the Wheelbase the less problem you should have. Bascially the top tube length can determine the position from the bottom bracket center to the wheel. Longer top tube/bigger size bike, shouldn't have a problem with tyres hitting pedals.

You may be able to push the cleat up towards your toes. This may give you enough clearance for the tire.

Thsi issue is by no means definite. You can get frames that do not do this in a 16". Heck, I saw a 16" On One 29er the other day. The guy had small feet and hence no foot rub. But it was definitely close.

If someone can make a 29er that doesn't rub, everybody can make a 26er in 16" that doesn't rub. If the bike is BRAND new ... you may try to return it in favor of a bike WITHOUT the tire rub.
