Excellent service and excellent product. I'd been searching for a emplacement for my 1982 30T chainring, and this is doing the job very well. Thank you.

Can I use this to turn a Stronglight (series 99) double into a triple?

And are you able to supply the longer bolts and spacers required to do that?

Many thanks
Unfortunately we do not have the direct experience of this / the relevant parts to suit.

Center To Center Distance On Hole Pattern

I need to know the center to center distance between two chain ring holes to verify it will fit on my chain ring.

Thank you.
Hi, the center to center bolt hole measurement for this chain ring is 50.3mm when measuring two adjacent bolt holes. Regards
