I'm hoping someone can point me in the right direction here... I'd like to try a smaller chainring on my son's new Spawn Banshee. We live in Vermont, all trails go up. The stock 28 tooth is OK on flats, but I'd like to swap a 22 or 24 tooth on there and see if it helps him be able to ride more of the trail.
I had a Shimano 22 tooth from one of my old bikes in the spare parts box, so I pulled the crank, took off the 28 and lined up the 22. Holes are in the right spot, 64 BCD. BUT the chainring bolts/nuts are too wide to fit through the chain ring. The 22 must be designed to just have the "bolt" go through it, right into the spider/crank- but in the Banshee there is a spacer, a thin bashguard, then the spider/crank, so it uses the bolt and the receiving nut that has a wider diameter.
So, can I get smaller chainring nut/bolt combos to fit through the hole in the 22t? Or can I get a 22/24/26 tooth chain ring with the larger diameter bolt hole? I've looked around the web a bit for 64bcd single speed chainrings (thinking they'd have normal size holes) but didn't see anything so small.
Any advice would be greatly appreciated! I am also working on a 3 sod set up for the rear like several others have done. Currently building up a wheel with new hub to take the 3 spd free wheel. But that is a whole other story.
