Tips to use as a spacer for the sprocket bolt? Got about a 3mm gap, so I can't tighten the sprocket bolt, or the sprocket wouldn't be straight.
Or should I just ask the LBS?
i've only seen a sprocket bolt spacer once since i started riding. most places don't really have them (never hurt to ask tho, of course). a few options off the top of my head:
1. i'm assuming you spaced out the sprocket from the crank arm at the moment? it's good for alignment yes, but an ill fitted sprocket bolt/space will give you more problems. go the second best route of spacing the sprocket out instead
2. machine one from a small diameter spacer, if you have access to the tools. it's not hard to drill a hole to correct size, will need a bit more sophistication to make it 3mm thick tho - and if you're already doing this, you might as well consider option 3
3. machine a single unit spacer. basically just a flat piece of metal at consistent thickness, then you drill one hole for the crankarm axle and one for the sprocket bolt. it'd be nice and clean this way, and you'll ensure the two areas are spaced the same amount. *do note to use steel/7075 tho, i've used 6xxx series before, worked well for a while but the crankarm axle hole experienced some crushing.
