The Stu Stick is simple but it gets the job done. Named for the famed cyclocross team mechanic and retailer Stu Thorne, this new aluminum offering from Abbey Bike Tools weighs just 44 grams, so it is lighter than steel rotor tools, but also includes a bottle opener. Not everyone might need a brake rotor straightening tool, but considering this one is so light there is no reason not to have it on race day.
