More Newbie Questions... Short Wheelbase, Durable Tires?wb
Jul 27, 2002 9:18 AM
Hi all,
Just a couple of quick questions. Firstly on my road bike I noticed that with my cranks level my front foot overlaps the front wheel, so that in a very slow turn my tire could in come in contact with my foot. Is this typical with road bikes, as on the mtb there is plenty of clearance. I doubt it would ever be an issue when actually riding but I am curious if this is normal. Also my Trek 2200 came with Bonty Racelite tires and with two flats caused by punctures in the last week, it seems I might need more durable tires or are liners available for road tires? Has anyone had experience with these tires and found them to be especially puncture prone? Any input is appreciated.

I used to ride Vittoria Kevlar belted and didn't have a single flat in the 4 or 5 years I used them. Then they wore out and have tried Specialized (which totally sucked - blew multiple tubes trying to get them on the rim and then they wore out after only a few months) and Continentals. I had a blowout on the Contis after three rides b/c I ran something over (i.e. it wasn't the fault of the tire), but I am going back to Vittorias.

Does not exist on all road bikes, but on smaller frame sizes (approx. 53 cm and under) is not uncommon. Factors include not just tt length but also headtube angle, fork rake, crank arm length, and shoe size.

You'll probably never notice it. There are a few tricks to taking slow turns with toe overlap, which include "ratcheting" the inside foot so that the outside foot (the one that would make contact with the wheel) never winds up in that forward position.

Obviously, coasting through turns (with feet at 6 and 12 o'clock) is the easiest, but some turns (esp. on uphills) simply require some pedaling.
You sure your flats were punctures?Spoke Wrench

Lots of new bikes suffer repeated flats due to crummy rim strips. Check your flattened inner tubes to see if the holes are on the outside or inside circumference. If it's on the inside, check your rim strip to see if one of the spoke holes is partially uncovered.

If it's on the outside, make sure you don't have a piece of glass still imbedded in your tire.

Thanks all for the replies. Since I ride a 52cm it seems I fall right in the size range where overlap may occur but like you said I seriously doubt it will ever be and issue. As for the flats, they were both clearly punctures caused by shards of glass, you can see the cuts in the tire as well as the tubes. Maybe just a run of bad luck?

Thanks again,
