Part 1: Surly cog won’t come off hub??
So the other night I was going reeeally fast (of course), and hit the mother of potholes. My wheel was shot. Couldn’t true it. Rim is bent. So, I went to my local LBS (Montano Velo in Oakland) and bought a new rear wheel: IRO hub with Velocity rim. I figured I could build up a new rear wheel around my existing Surly hub later on. When I got home and tried to take the cog and lockring (both Surly) off of my hub, after taking the lockring off with a little effort it turned out to be IMPOSSIBLE to get the cog off. On the advice of a mechanic, I had put it on with Loctite. Anyway, I broke my pinche chainwhip trying to get it off. I decided to throw the bent wheel back on my bike and tried to skid my way down a hill thinking that would surely unscrew my cog. Nope. Won’t come off. And I weigh 220 lbs. So, I was wondering… is this a problem with the Surly cog? The loctite method? Happened to anyone?
Part 2: Noisy drivetrain with new wheel/cog??
Since I couldn’t get my cog off, I ran back to Montano Velo to buy a new cog and lockring. I decided to get a different size (I was using a 17t, but bought an 18t). I threw it on my new wheel (using grease instead of loctite this time), cleaned my chain, and went on a ride. The resulting drivetrain was so loud I couldn’t even hear the voices in my head. Before, with the old cog and wheel, the drivetrain was silent. This hasn’t ever happened to me before. Is it because I switched to the 18 tooth cog and my chain objected? Any ideas on what I can do to make the sound go away? As I mentioned above, I can’t just switche to my other 17t cog since it’s unrepentedly stuck.
