Johnny 55 Posted March 3, 2022 Share Hi guys. I recently bought a giant stance and cant seem to determine the bcd on my chainring. I have a 2x9 deore setup wirh alivio shifters🤣 and want to go single speed. The crankset is a Comet Fsa 2x. I just dont wanna order the wrong chainring. I think its 96 or 104 but not sure. Please help and thanks. Link to comment Share on other sites More sharing options...
RobertWhitehead Posted March 3, 2022 Share Measure the diagonal bolt distance. Chances are it is a 104 PCD but just measure to confirm. Edited March 3, 2022 by RobertWhitehead Image added Sid the Sloth and peetwindhoek 1 1 Link to comment Share on other sites More sharing options...

BaGearA Posted March 3, 2022 Share Centre of bolt head to centre of bolt head otherwise you might still be ordering something that won't fit Link to comment Share on other sites More sharing options...
droo Posted March 4, 2022 Share Take the chainring off and measure. It's FSA, it'll probably be something unique and unavailable. Link to comment Share on other sites More sharing options...
Johnny 55 Posted March 4, 2022 Share Lets hope so yes. Seems to be 96bcd. Link to comment Share on other sites More sharing options...

No disrespect to the agents, they just have a massive and weird inventory to try and manage and do pretty well despite this. Link to comment Share on other sites More sharing options...
Psyrax Posted May 18, 2022 Share The BCD of every chainring should be written on the chainrings. Take the chainrings off and look on the "inside", bike side of the ring. Link to comment Share on other sites More sharing options...
Jewbacca Posted May 19, 2022 Share In one click of googlefu I discovered it is 96bcd, the spider is removable and you do in fact get direct mount chainrings for it.... Here is a website where you can order one from for a whopping R449; https://capegrosports.co.za/products/fsa-comet-mtb-modular-chainring-1x-dm I usually charge R400 an hour to do research for other people but luckily that was 1st page 2 clicketyclicketies...... It's a pleasure Bongo, Mtree, peetwindhoek and 1 other 2 2 Link to comment Share on other sites More sharing options...
