I thought they couldn't cope with the ??2-way?? torque created when riding fixed, unless its been changed now

Also on road frames with custom work to accommodate for chainline. Sticking a road crank on a track frame works but the chainline isn't perfect.

I would think the pinarello frame is a standard off the shelf..and somehow using spacers or something at the BB to get the chainline but just wanted to confirm..

I've used a dura ace 7800 chainset on my track bike for years with a 130bcd ta ring. Some tweaking is needed to achieve a perfect chainline, but in my experience it doesn't affect things as much as you may think.

Interesting how this issue has been receiving more attention now stock road tt frames are being tweaked for the hour record, seen some really trick custom spacers etc..

Its easy to get a perfect chainline with a road crank, just have Campagnolo or Shimano machine you a custom ring...
