My mtb bike got ripped off from the front of my house several weeks ago. After a few days of depression ( I had the bike for nine years) I took the 42 chainring off and put the 48 on my fixed. I rode as hard as I could for about an hour. It was great therapy. I averaged close to 22 mph over rolling stuff.

I had been using my fixed mostly to spin and recover from road rides. I usually switch to a bigger ring this time of the year anyway but had not done so. I am going to leave the big ring on and even try the 52 to see what happens.

I have separate chains for the two rings I have now. Is it common to remove and replace links in a track chain to acommodate different size gears or do most people have a chain for each set up?

it's never a good idea to keep taking out and putting back links over and over, as it severely weakens the chain. two chains sounds good for that kind of thing.

most people don't mess with the ring; they have 2 or 3 cogs, all of which fit on the same chain by moving the wheel back and forth for tension.

Ditto. Having snapped a chain while ont he way to work it is a pain the buttocks to fix and then show up at work with grease everywhere.(exageration)

Like ShrimpX says, I don't mess with rings. It's much easier and faster to just swap cogs since a one tooth difference in each cog size is pretty much equivalent to a difference of 3 or 4 tooth in ring size.

George!
