My forks developed a hairline crack after around 4 months of use at the top of the disk mount. Incidentally, they were the Echo forks I bought off you. So I bought some new ones (Controls again) and measured them up to one another, and the ones I bought from you were significantly shorter, mod length style... Turns out I'd been running mod forks on my stock, which actually worked really well. So just FYI, they wern't Controls, they were Echo Lites EDIT: Threadstarter, thats about the 16th pair of Urbans i've seen go there. Have you used a Magura before you went to disk? Its the rearward facing magura mounts that does it, causes vibrations and thats the end of that.
