|Toe Overlap||The Real Garbanzo|
Jan 5, 2002 4:23 PM
|Ok, I just got a Surly Crosscheck and have some toe overlap issues. I'm just wondering if it's a normal thing or the design is screwed up. I've never had toe overlap problems with road bikes...
I've heard that is common in cx bikes to have overlap...is this true?

|on my 52cm Poprad. It only happens at low speed big turns, like cranking a "U" in the street. My toe gets a good buzz, but the wheel isn't restriced in terms of making the turn. I'd be curious to hear how common this is.|

|On my colnago and graham weigh I have overlap issues. |
Even going to a shorter crank size would not help.
I have a few problems:
I like larger crank arms.
I don't have small feet.
The trend with cross bikes is to shorten the top tube and raise the bottom bracket.
If my math is correct this is most common with smaller cyclocross frames i.e. 52cm and below...perhaps.
One way to avoid this overlap issue is to make cyclocross frames with 26" wheels and availablitiy to decent, legal, race ready 26" tires.

|I have the same issue with my CX bike as does most of the folks I ride with. I believe it is just the nature of the geometry difference between a road bike and a CX bike. There would be no way to change it without adversely affecting the overall handling and ride of the CX bike. As long as you are at speed it is not a problem. I just stay away from u-turns and track stands on my CX bike.|

|I think it is due to the fact that the cross tire outside diameter is larger than that of a road bike's not any geometry difference. In fact, most road bikes have a shorter front center dimension than most cross bikes have.....|

|It's the tire that does it for me, more than the CX geometry. My VooDoo has 175 cranks and I use MTB shoes a size bigger than usual to accomodate thick socks. I've got severe toe overlap when I run a chubby, tall Ritchey Alpa-Bite (700x35), less when I'm using a 32mm TUFO Rhino tubular, and virtually none with a slick road tire on the front. |

|Nothing to worry about. I've got size 12 feet and overlap slightly on most of my bikes. Crit bikes, for example, have short wheel bases, steeper head tube angles for cornering. Overlap is common, unless you have small feet or short cranks. this certainly won't create a dangerous situation, as the only time you will rub is a really slow speeds.|
