LOL. I just checked and the chain is way too long for the 18-30 combo and too short to reach the 48-13 combo. I think I’ll just keep the saddle and donate the bike to the co-op where it can be used for parts. Or if someone were to remove the 18 up front and put in a 28 and then put on a new chain it might be a decent bike. Interesting thing that was done to this bike...
