Now who's assuming ? I've never crashed due to a mechanical, and never as a result of something I've worked on myself. You know nothing of my mechanical experience. Having built, maintained, raced and crewed for championship winning racing vehicles for 30+ years, my skill set is solid. It's your own expertise you truly question, not mine Rick. That's entirely clear. Although I'm sure you could handle fixing a machine as simple as a bicycle, if you took the time to learn to do so. You wish to throw money at things rather than increasing your skills and knowledge. Your choice. Also your choice to trust someone else to do your work for you. Perhaps you should pay someone to ride it for you as well.Lucky for you you've found a solid shop, as that is not always the case. The competent shop guys on here I'm sure can tell many stories of poor workmanship they've had brought to them from other shops. Brought to them by folks who belived the shop they tried first had "expertise".
