The bolts are attaching my rear rack to the frame. 2 out of 5 are seized up, one at the top one at the bottom. All of the other bolts are fine.EDIT, what bolts?
I perfectly understand your motivation.Yeah it's a small amount total, but in terms of % points, it's like I'm paying double compared to these guys kinda thing. Went to town for other business today and dropped by Y's. The pads were 1900yen plus, and tax excluded. So that seems to be what it is in Japan.
On my mountain bike 3,000-4,000 km, I think. With mountain bikes it really depends on how clean you keep your drive train and what kind of abuse you subject your bike to. Front chain rings last about 7,000-8,000 km, I think. On my road bike the front chain rings look like they are in pretty good nick. I have had to change the chain once, but can’t really say how long it lasted, because I don’t know how many km @Karl put on the bike before selling it to me.
This guy gets 15000kms out of one chain with his chain wax (around min. 5.30-6.30). According to him, the cassette has to be replaced after 3 chains (45000kms). That's a lot of riding...
Maybe that 2,000 mile rule is for optimal performance on a proper racing bike. I’ve done about 4,000 km on my CAAD since I got it and the drivetrain is not so snappy anymore/ shifting’s noticeably worse. I imagine I’ll end up replacing the chain at the same time I get the cables done. Tbh, I’m probably going to have my LBS do all that.Yeah I'm not complaining that chains last long, but my experience would be 5 to 6 thousands km and still no sign of wear. Cassettes, chain rings, much much more, can't even estimate those, esp chain rings. So all's good apparently. Thanks
I wax. (TMI, I know.) Usually get 5,000 km or so from a chain. I have a chain wear tool to get an objective verdict. With three bikes in regular use it's more effort to keep track than to just wax 'em all and check 'em at the same time. Switching from 8 -> 9 -> 10 -> 11-speed over the years, I have subjectively noticed that shifting precision has become more sensitive to chain wear. (Everything's on 11S now, so I only have to keep one spare chain.)
