I have a 1994 GT that I have added many upgrades to. I would like to get rid of the old FC-TY21 crank set. I really like the hollow tech parts like Deore or DLX. Can I swap this stuff in? Spindle length on the original parts is supposed to be 122.5 mm per http://www.shimano.com/publish/content/global_cycle/en/us/index/tech_support/tech_tips.download.-Par50rparsys-0032-downloadFile.html/05)%20Crankset%20and%20BB%20Combination%20Chart.pdf Will this equipment interchange?
1994 GT Outpost Trail, most stuff changed
1995 Schwinn 95.3 very stock
