Mistral Synergy - bottom bracket info

[bigbadal]

Just for info. My old Mistral Synergys pedals went "loose" last week making it extremely difficult to ride. On inspection I found a totally disintegrated bearing. I thought I'd be able to get a bog standard all in one bottom bracket but quickly discovered this is not a standard size. The spindle is 141mm long. the actual bracket is 85mm wide. I decided I'd try and replace the faulty bearing. The bearings on the spindle are marked up as 6002 which is a standard size right? Looking up 6002 bearings I found they are 32mm outside, 15mm inside and 9mm wide. So I ordered them from simply bearings Ltd and they arrived the next morning. Disappointingly the 6002 bearings were not the right size I needed. I had to get a vernier and measure the bearings. They are in fact 31mm outside 16mm inside and 10 mm wide. I ordered the correct ones and again simply bearing s Ltd got them to me the next morning (fantastic service from them). I fitted the bearing and have the bike running again. I really don't know what I'd do if the spindle broke in any way as 141mm length spindles don't seem to exist as far as I could see. So I'm just posting this up in case anyone else has an old Synergy with a broken bearing.

You canget 83mm ISIS BBs from Cycone that would probably be OK.

I think Sickbikebikeparts.com also has a cup and cone square taper one.

thanks for that info - I had given up searching and so ended up just replacing the bearings. It's good to see there is a BB that would probably fit my old bike. thanks for that d8veh
