Help Me Out Here Guys...don't need no stinkin' Overlap!hawker12

I know that a lot of smaller frame bikes have toeclip overlap but my old Cannondale does not and I just can't get used to it.
I've had some almost-falls with my new bike and I'm tired of being concerned about it.

So...who has a 48-50cm road bike with 170mm cranks and no overlap? I'm 5'4" with a 28" inseam and size 42 shoe.

Thanks very much.

I ride 51cm frames and all my bikes have overlap. Good luck finding one without overlap...

I ride 49.5-51 CTC bikes except my Colnago which is a 51, their measure. No overlap unlike the rest of my machines. Long front from BB to fork end.
I suspect it's pretty common.Greg B

I ride a 55cm with size 45 shoes and have overlap as well.

I too have gotten used to it.

You need to learn to handle the situations that caused the almost-falls, rather than give up on the bike.

My Fondriest with a 57cm front-center, creates a bit of toe overlap with my 42.5 shoes, but I don't even notice it. About the only time that the wheel should be turned enough to create a problem would be during a very slow speed maneuver, or perhaps a shakey take off after a stop.

As far as who makes a bike that might not have the toe overlap, you need to know what the minimum front-center dimension that you need is and compare the front-center dimension of the geometry charts from various manufacturers. Cannondale lists the front-centers of their 48 and 50cm road frames at 56 and 57.1cm respectively. The 48cm frame would definitely have toe overlap with a size 42 shoe. Even the 50cm might barely have clearance.

Colnago frames in your size have much longer front-center dimensions around 58.8cm. LOOK frames also have front-centers just over 57cm, but the smallest size of some models is 49cm, measured c-c , which is 50.5cm measured center to top.
My bike has it too -- don't really notice itdgangi

My 54CM Fuji also has a little overlap and I wear a 42 shoe. The only time it ever becomes an issue is with *slow* manuevers where I have to really crank the wheel to make a turn (such as zig-zagging up the switchbacks on a footbridge).

My friend says his bike, a 58CM, also has overlap.

I think the short wheelbase bikes of today all have overlap to some degree or another.

it's just part of the game on smaller bikes, I'm afraid ... but on road bikes, it shouldn't matter. I touched toes with my front wheel while racing CX, and I was fine. it's easy to learn to live with. the only small frames without toe overlap will probably be MTB frames.
Surprised you even notice it--it's really common.Silverback

I have overlap on two of my three road bikes, and I didn't even know until somebody asked me and I checked. I'd ridden them at least 8,000 miles without ever touching, including a couple of thousand offroad with the faux-cyclocrosser. Are you really fouling the front wheel, or just worried that you might?
Same story here. It has been a non-issue...exceptKristin

If you are ascending at a really slow pace and you swivel your front wheel, you might go down. You're only going about 3MPH, so its not a big deal, except you probably will have to walk up the rest of the hill. I was in this exact situation last weekend and only missed the wheel by a couple degrees. If my right foot had been at 3 o'clock, I would have knocked myself over. I could have taken a couple other riders with me. That, and turning slow circles, are the only toe clip risks I've encountered.

Thanks for your help guys. Somone mentioned that the front-center measurement was the key...and I believe that is probably a very good observation. NO..I'm not just "worried" about it, I've had it happen several times. It happens if I am turning around at the end of a street and I try to pedal through the turn, it happens if I sort of lose my balance when starting up...maybe when going uphill or in too high a gear Also, when making a 180 at a stoplight to go in the opposite direction...IF all of a sudden I need a little extra burst of speed and the cranks happen to be in the 3 0'clock position. Once I even got my toe caught on the opposite of the wheel..and down I went.

I am not a new rider but this new frame has a shorter top tube and the overlap is at least an inch and a half...maybe a little more.

Thanks again.
