Got my Zipp back; Rear brake problem is warranty item.
I’m happy to report that I was able to pick up my re-laced Zipp 404 yesterday (see “Broken spoke on Saturday“). Steve, the wheel builder who did the work, seems to have done a fantastic job. Also, because the wheel now has brass spoke nipples, hopefully I won’t have any more issues with galvanic corrosion. Even if I do (and my front wheel does still have aluminum nipples), at least now I know the correct procedure for dealing with that issue.
Some of you may recall that I have been having issues with my Madone’s rear brake (Bontrager Speed Limit integrated brakes). When I picked up my Zipp from the shop yesterday, I took my bike with me. The mechanic and I took a look at the caliper together, and he confirmed what I suspected: the caliper was malfunctioning and needed to be replaced. The brakes were properly adjusted, and nothing was wrong with the cable or cable housing.
I contacted my Trek rep, and he said the shop should initiate a warranty claim. They have done so (I need to submit a couple of photographs this morning), and soon my rear brake issue should fully resolved. It’s too bad the caliper is defective, but I have to admit that I’m glad it was not an adjustment issue or something I was doing wrong. Also, it’s nice to see Trek continuing to stand behind their bikes. Great service all around, from shop (David’s World Cycle) to manufacturer.
