|   Help Me Out Here Guys...don't need no stinkin' Overlap! | hawker12
Oct 20, 2003 7:14 PM | | 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.

Oct 21, 2003 3:33 AM | | I ride 51cm frames and all my bikes have overlap. Good luck finding one without overlap... |
| Colnago | boneman
Oct 21, 2003 1:47 PM | | 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
Oct 21, 2003 4:31 AM | | I ride a 55cm with size 45 shoes and have overlap as well.
I too have gotten used to it.

Oct 21, 2003 5:00 AM | | 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 it | dgangi
Oct 21, 2003 5:16 AM | | 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.
Thx...Doug |
| have it, lived with | weiwentg
Oct 21, 2003 5:34 AM | | 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
Oct 21, 2003 8:00 AM | | 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...except | Kristin
Oct 21, 2003 8:08 AM | | 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. |

Oct 21, 2003 6:03 PM | | 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.
