As was the aluminum stem and low end RD TY15 rear derailleur.My second favorite saddle was attched to the original Grand Prix seatpost.But as soon as I put a few miles on them the sidewalls started showing trouble. But this observation was only available because time had degraded the outer sidewall rubber enough to expose them.Although buying a used bike for its used tires was foolish, the Trek 720 has become popular with my wife and will be her commuter bike.My unused Giant Iguana mountain bike donated its seven speed rear trigger shifter.Shimano 105 brake levers were installed and cabled up to some really old, unmarked, center pull brake calipers. "Cyclocross David", a single speed rider, inspired my purposeful omission of this component, its shifter, and attendant cabling.The first test ride was uneventful with no serious issues. The Grand Prix frame did not have a derailleur hanger.
Although the 700c 23mm Continental Ultra Gatorskin tires allowed the bike to roll fast and free, they offered little rim protection when hopping up and down curbs and navigating the occasional dirt path.Despite the short-for-this-world tires the bike was ridden. And a set of Planet Bike black 45mm Cascadia fenders were immediately ordered.These fenders are Planet Bike's top of the line plastic fenders.The bottom bracket was 'sticky' but responded well to a thorough cleaning and fresh grease.The bottom frame headset cup was no longer tight in the frame.
