New groupset on 2005 HT stumpjumper
I've got a 2005 hard tail stumpjumper that I use as my daily hack riding to work. It's done a lot of miles and needs a total overhaul. I've also got a 2018 Specialized Enduro, but find the gearing sadly lacking with only 42 tooth big cog at the back and some serious techy climbs round here. Would love to upgrade the groupset on my Enduro and use the 1x I take off on my old stumpjumper as gearing would be perfect for the commute. Is it even possible, or is a 2005 frame and wheelset so different as to be impossible?
