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 8x20/18 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.

Cheers!
I.

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

No idea on pitch etc.

Hi,

The search is still on. On-One bolts are only 12mm ๐Ÿ™

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!
I.
