Trekkin

Hi guys, brand new to the forum. My grandfather gave me his daily commuter, a trek 1000. I put some continental700x32 cyclo x kings on it because I live where there is a lot of dirt/road mix. The tires were a little big and the was able to do some minor filing to the bottom of the back brake but the front wheel rubs on the sides of the fork. Does anyone know if the bontragwr forks that came on the bike are full carbon? If not where does the alloy end and the carbon begin? Would love to just file a few mm off the top inside and make the wheels fit, the trek site just says bontrager carbon and nothing else for the forks. Thanks guys!

Don't do that. Get smaller tires. You could die. </thread>

Get proper fitting tires

That should work. Just make sure you use a carbon-specific frame file, the steel/aluminum files are too coarse a grit and may damage the carbon. Also make sure once you're done filing you smear some JB Weld over the indents to preserve structural integrity. Good luck!

It appears as though the top of the fork and the first few inches of the blades are metal, my question is, do they make forks that are a mix of both?

They do.

But in case it wasn't obvious, you absolutely should not file down any fork or frame material. You could potentially find a fork that fits your frame that would give you more tire clearance if you insist on running extra-wide tires.
