Had a mate ring me today to come over ostensibly for a few basic maintenance tips and ask what tools to buy. Well 6 hours later, including lunch and a trip to the bike shop for parts we did a major service.
Cranks off, BB checked ok; chain and cluster both showing severe wear, install new; hubs repacked as cones were rough as (this after a full shop service)
New bar tape and front wheel trued. Brake blocks aligned and cables retightened. Gears adjusted.
He's happy and I scored a nice bottle of red. A good day, just hope he picked up a few tips.
