Apparently, I'm Tough on The Equipment...
As I was rolling the snow bike out of my cubicle, today, at quitting time, I heard an odd sound as I rolled around the corner. With a sneaking suspicion that I knew what was wrong, I looked at the rear wheel as I pushed the bike along the hallway.
Sure enough, the rim was tweaking over and hitting the brake pad. I stopped and looked more closely at the wheel. Sure enough; I had another broken spoke. It's the fourth broken spoke I've had on this bike; three on this wheel, one on the Rolf wheel with the non-studded tires.
I have no idea what the problem is. The spokes on the bike are 14 gauge, stainless steel spokes. That's pretty standard for mid-grade mountain bike wheels. The rims are fine, and the hubs are in good shape. The wheels (which were on the bike when I bought it) look to be in good shape, with no evidence of hard use/abuse. But, I'm losing spokes like a meth head loses teeth.
Luckily, the roads have pretty much cleared off with the warmer temps we had, today. So, I'll ride the yellow bike, tomorrow. Even if the roads were still icy, I think I'd just put the 700c studded tires on the yellow bike and ride it, any way, because I am tiring of replacing spokes. I might just build up another snow bike, and repurpose the DiamondBack.
