Dolan Pre Cursa / PreCursa / Track Champion

I'm having trouble with the pre cursa + stronglight track 2000 cranks.

After cleaning, greasing, re-fitting my cranks + chainring the spider catches the chainstay severely. Must be that I had fitted them terribly the first time. As far as I can work out my options are:

1. Swap my BB (stronglight JIS 107mm) to 110mm or longer. Live with shitty chainline for now (I need this bike for commuting). I don't think I can fit a spacer behind the cog because the lock ring would then not be completely on the threads. Maybe down the road I can get myself a new rear wheel/hub with a non-standard big chainline?

2. New cranks. Can anyone recommend me some cheapish cranks that fit on the pre cursa and give 42mm chainline?

New cranks are the easiest answer to this. You can not get a 42mm chainline or close to it with the Stronglight 2000 cranks on the Pre Cursa as the spider will hit the very wide chainstays. The chanstays flare out too much for a track bike as they are designed to accommodate tyres of 32c or above, this is a pain with some cranks.

The Stronglight 2000s are decent cranks but are roughly finished and have a very fat spider, this is in itself no problem at all on many frames like my PX carbon but they are unfortunately unsuitable on a Pre Cursa.

Go to page 8 of this thread to see the problem I had with the Stronglights and this frame with photos. I still have not got around to getting new cranks for it yet myself.
