Just got my Langster and it came with 48 x 16 free. Want to ride it fixed, it has the lockring already. Waaay too hilly here for me to use the 48 (will work fine for the track, however). Would like to go with a 42 up front. Can't find these in 1/8" 130mm. Can I use my old road 3/32" ring, or will that cause too much chain slop? Guess there's not much call for a 42 'granny' track ring, huh? Don't tell me, check with Sheldon....

or you can buy a bigger cog.

or you can buy a 3/32" cog and chain to go with your 3/32" 42t ring.

Or, you can go to a bike shop and order a Salsa ring. That's what I did.

...if you cannot get one locally or if your LBS charges a bunch for special orders...He had some 1/8 x 130 x 42 NOS rings in stock a year or so ago, IIRC. Also had 44s...

He's also got 1/8th cogs up to 20+T, though I'd recommend staying at 18T or below as to keep too much torque off the rear hub threads...especially if you're rough on skids...

FYI, I've found that an all 1/8th or all 3/32nd drivetrain is much quieter than a mixed one. Running mixed isn't a big deal, but running all same size stuff really seems quieter.

Pretty sure these are 130bcd and available in 1/8th. I think they go as low as 42t as well....
