And it begins.
I was just browsing craigslist for deals like the dealfreak i am, when i happened to come across a kilo tt with sugino RD cranks and other upgrades for $350. I thought it was time to treat myself, so i talked the dude down to 300 and picked up a toy. Heres the issue. I start riding, and notice theres some annoying toe overlap at slow speeds, i dont think much of it tho until i go home to change out the wheels. I look and see that the crank is 172.5mm?? Da ****? :twitchy:
Is this a dangerous set-up for fast, brakeless, city riding?

You didnt test ride before you picked it up? That issue should have been looked for before the purchase. Besides, Kilo TT Pro's are 400 (w/tax, shipping.) They have rd's, as well as sealed hubs to better rims, etc - 300 dollars is a "meh" kinda deal to me. I've seen better.
Fast, city riding should never be done brakeless. However, going fast, you might not notice the massive overlap. If you have short legs, thats another issue, another one that could have been solved with a longer test ride.
Depending on the size of the bike, 172.5 could be severe overlap to light overlap - though the kilo comes with light overlap even with 165's. What size is it?
If all else fails, run it singlespeed with two brakes. Toe overlap will not be a problem as you can turn and coast. I repeat, two brakes singlespeed. My advice is at least one fixed. I prefer to have two - one for backup, you never know. You will be allowed to have higher gearing -> faster high speed with brakes, and not have to go slowly because you can't stop in time.
Edit as to add to Vixtor's post:
A sugino xd 165mm is about 60-70 bucks. The bb required is the same.
Run a brake.

I think he's more concerned with pedal strike when cornering a tight corner. If you are going 25+mph and leaning really close into the turn, you might strike your pedal. Kilo TT Pro's bottom bracket shell is kind of high though; if you are really paranoid about it, change length.

xkillmailx I've got the picture, get a brake. its a 53cm, and I did test ride it, but i didnt go out of my way and do highspeed turns. I'm not that paranoid about it, but im just curious as to whether or not it would be dangerous if the crank hit the ground at a highspeed turn...
Also, if you cared to read the post, there were several upgrades. it was basically a completely new bike with the same frame and wheels.
