Got some carbon trigon forks but unfortunatly the steerer is only 167mm...any ideas to get these babies on me bike....looked at low stack headsets first of all.....crank bros with a 21mm stack so i should save 10mm on setup i have now.Also not looked into low stack stems yet,they would prolly need a decent rise also.Is there anyway to extent the steerer on these? some sort of extention? thx
