Hi,

Got problem. Bought old RF Turbine cranks. It is very old type, where for mounting granny ring you need some spacers. Got spacer but found out that 16mm bolts are too short. Estimating that will need at least 18-20mm bolts. The problem is that they are not standard M8 bolts pich (that is 1.25). Chainring bolts have pitch of 0.75. Any idea where to buy such bolts, not necesarry chainring specified.
Just right size 8×20/18 pitch 0.75.

Found something that might do the trick but the price is really outrageous. Over 5 quid per single bolt >:(

Every input will be highly appreciated.

E13 do some long ones to use with their fat bashrings

Aren’t on-one swap-out bolts just long chainring bolts?

No idea on pitch etc.

Cheers chaps!

E13 are only 15mm long, but sent an e-mail to On-One guys.
Fingers crossed.

Hi,

The search is still on. On-One bolts are only 12mm 🙁

Had a reply from Tibolts, but they said that they won’t have anything available in 10weeks.

Any idea of somebody making custom bolts if stock are not available?

Cheers!
