When I was back home (Northern Ireland) visiting family and friends over christmas, a friend and I 'fixed' a crappy cheap MTB that someone had given to my dad. we just, again, used what we had lying around. could only find a 13T cog so ground the bigger two rings off another MTB's chainset leaving the granny ring (28T 56"), looks a bit silly having such a small drive train but coupled with the high BB gives shit loads of clearance. tons of fun to boot.
