To finish off, we have a BMC Street Racer that, due to injury, had been laid up for a while. Perished tyres, a rusted chain and general neglect were soon forgotten after it received an Annual Service, new Continental Gatorskin tyres (as you can see, these are currently flying out the door!) and a KMC Chain Europe B.V. chain. Now in tip-top condition, the @Shimano 105 groupset can really do its things once more. A slight change of pace, and this Specialized Bicycles Crosstrail had mis-firing gears. Some adjustment to both the high and low stops, along with the cable tension, and crisp consistent gear changes were the result.
