My lbs is owned by an old racer, great mechanic, fast and cheap too. He tells me never to adjust my bike because I mess it up. Lol. He wants to do it. He once seen me riding and pulled alongside in his truck and gave me tips on climbing. Lol
Great guy. Idk if I'd love cycling as much if it wasn't for him.
The old racers have there opinions, but my lbs owner knows it's a business, so he never turns down whatever odd bit you could want on your bike
