My new (to me) track bike came with two 3/32 cogs and chains. I think the 42T chainring (144mm bolt circle) is also 3/32". I just got my DA hi-flange 32 spoke 3X Mavic Reflex tubular wheelset built by my LBS and while I was there I bought a DA 16 teeth cog in a 1/8" width and a matching 1/8" Sram chain.
My question to some FG old timers is will the real track cog and chain work with the old chainring?
I ordered a 44T TA chainring in the 1/8" width online but would like to ride the bike soon, like tommorrow, hence my question. Thanks. Gerry

yes. the 1/8th will work on the 3/32nd stuff, but a 3/32nd chain will not work on 1/8th equipment.

Yes.

Thanks guys! If it fits will it cause me any unusual wear issues? When the correct width 44T chainring arrives I will bolt it on as I really prefer the 44X16 ratio (74.4") for spinning down the hills around here and not having to touch my brakes. Yes I run BOTH front and rear ones; just in case. Gerry

no i dont think you will notice any unusual wear on your gear, especially if you have a nice and straight chainline. i know a few track racers who use 3/32nd stuff with a 1/8th chain.

while i cant say this for a fact (i am just hypothesizing), i would imagine that any wear that would happen would be on the 3/32nd stuff you are getting rid of anyway, as the chain might have a little side to side movement that might wear it down a bit quicker than normal. i dont think this will be an issue at all though. anyone is welcome to correct me if I am wrong.

i've been running a 1/8" chain on a 3/32" drivetrain for a while. no problems reported thus far. since the chain can move a bit more laterally i suppose the rollers could possibly wear against the valleys between the teeth with a bad chainline, but it hasn't been an issue for me.

Thanks for the replies guys. Gerry
