I have a 2005 Giant Yukon hardtail that I have made a number of changes on over the years. As I was lucky enough to purchase one of the new Trance X 29ers this fall, I am looking to kind of re-purpose the ol' guy once again. A couple of years back I replaced the crankset with a 3-ring Truvativ. With the help of a friend, we removed the outer chainring and replaced it with a bashguard. When the fork wore out, I replaced it with a 120mm 20mm thru axle Rock Shox. I also upgraded the wheelset to burlier Azonic Outlaws, put on a shorter stem and wider bars. I have the smallest frameset this model came in and my friend always thought it would make a sweet little indoor park bike.
I plan on building some small ladder bridges and stuff for the backyard to practice on and wanted to simplify the bike a bit more. With that in mind, I want to remove the front derailleur and make the bike a 1x8. My friend suggested I try to find a smaller chainring than the 32 middle. Unfortunately, I have not been able to find one. Keeping the middle chainring would also ensure that I have the best chainline, correct? That being said, would I need new chainring bolts that are shorter, to accept the bashguard and middle chainring (so it'd be essentially for a double chainring crankset)? Has anyone done this before on an old 3x8 drivetrain? Like I said, I don't want to spend money on new parts and wanted to see how feasible this would be.
Thanks in advance!
