Rear mech cable replacement mileage
Having snapped a rear mech cable in the shifter under the mechanism which resulted in me buying a second hand tiagra shifter from ebay for £ 27 for my winter bike, I want to avoid the same problem on my carbon shimano 105 equipped summer bike. It has now completed 3000 miles and I am wondering if it's time to replace the rear mech cable. Any advice on what mileage to renew the cable would be appreciated. I have lubed the cable on a regular basis, but haven't touched the mechanism.
