Bike question - Page 2

post #31 of 33
A word about chains. I currently run a sachs chain on my commuter ride (8 speed) and in my opinion it is not as good as the midrange shimano chain. Now I can't tell you the model because I can't remember. it's problably the cheaper one. I bought the sachs chain because I'd never used one before and wanted to see if I was missing something. Alas I was not. I've used Taya chains, Shimano chains, campy chains and sidisport chains, whatever chain seemed to be the chain of the moment. I've actually had freinds who used diferent chains on the same bike for different events! So as you can see some people are pretty darn obsessed by their chains.

All that said - despite the flak I might get for saying this - is that I think shimano provides a better product than some of the smaller component makers.

If no one has told you, one reason for replacing your chain is to reduce wear on your chainrings, primarily the rear one. If you put on a new chain you may find the chain skips or does not shift properly on the rear cassette. If this is the case, you need to replace your rear cassette. If you change your chain more frequently the cassette will not get worn out and it won't require replacement. Now - I can't tell you how often to change your chain because it has much to do with how much you ride - which gears you ride - and the terrain you ride. I can tell you that it has been my experience that if I change a chain three or four times a season (I ride a lot) that's about the same price as one new chain plus one new cassette. So if you only ride one set of wheels it's a wash on cost. it's a little different if you have two sets of wheels because you have two cassettes to worry about.

It's not the size of the ship, it's the motion of the ocean, right?

Anyway, I took my bike to the LBS, and they put a chain tester thinghy mabobber (that's a technical term - use it wisely) on it, and told me my chain was shot. Beyond shot. The little tester tests the side play, and my chain had way too much. I guess that could make it harder to get the bike into gear, huh?

For a supposedly "good" LBS, I was a bit surprised that they immediately assumed, without asking, that I was just going to leave my bike there and let them swap my chain and adjust my derailleur. Do these people just assume everyone is inept? C'mon. If you're into mountain biking, you probably know a thing or two about bikes, right? Not like I run crying to a shop if I blow a tire on a trail, and ask them to fix my tire, right? I still haven't put it on yet, though. I was too busy this weekend. And there won't be any riding this week. It's gonna rain all week. lovely.

It must have been the chain guard and king of spades held into the front wheel by a clothes pin on the front fork!

No, I wouldn't have expected that top end riders don't know how to fix a bike. I would, however, assume that they let paid techs work on their race bikes, the same as Meier has a tech to tune his skis, and Darrel Waltrip lets his pit crew work on his cars. But these guys DO know how to work on their equipment, and usually love to (especially NASCAR gearheads). I mean, how does one become a top athelete??? They start out at the bottom, and work their way up. And during that process, they would work on their equipment. Especially in such an equipment intensive sport. Chalk this one up to the "who'd a thunk it?" department.
