Our Wound Up Tandem Duo fork is showing discoloration/spotting where the brakes attach to the fork. The clear coat is clean and feels mostly smooth to the touch, except right at the metal/carbon junction. The fork is designed for both disc and linear pull brakes, although to date we have used only the linear pull. The problem areas are next to both brakes. The rest of the fork looks clear. The fork is two years old, with roughly 7,000-8,000 miles. Bike frame is ti. Team is 310 pounds.
Our retailer (Mel at Tandems East) is to talk to the manufacturer. Also, a local carbon repair guru will have a look at it. In the meantime, we're curious if anyone has had a similar experience or has a theory about what's happening. If this is merely cosmetic, we don't care much. If it's potentially more than cosmetic, then obviously we care a ton.
Appreciate your thoughts. Cheers all!
