My husband crashed his Le Monde and we were able to find a Trek TCT 5000 frame to switch everything over. It is almost complete, but the shop does not have the bottom bracket cable guide for this bike. Apparently, it is unique to this particular model from Tiawan and it is no longer manufactured. How can we obtain this part? We have asked around at local Trek shops and they basically said "good luck." The shop guys say that this part snaps rather than screws in and is not inter-changealbe with the OCLV part. Any ideas?
