Ah ha! You ride in this smallest cog most of the time! Take another look but the back side of the teeth on that cog are most likely cupped (increasing slope of the tooth until it becomes an overhang near the top). This is good news as buying a new final cog is easy and much cheaper than a whole

I mean this in the nicest possible way, but unless I'm misunderstanding something terribly, there's no way you should be spending 70% of your time riding in your highest gear. It makes my knees hurt just thinking about it. You should be trying to ride in approximately the 90-100RPM range. "S

I tried looking at the cog but I can't tell much. I'm not very mechanical. I'll look at the chainring too. It wasn't knocked out of adjustment because I watched him install it. I checked the master link. It looks ok. It may be the derailleur but I have friction shifters so I wouldn't think it

I needed a small chainring when I did my winter overhaul on the Hilsen. New chain and the hooky teeth wanted to pull it up like precursor to chainsuck. They were pretty sharkfin-ish. On Monday, April 16, 2012 11:48:18 AM UTC-7, Lynne Fitz wrote: > > Check your chainrings. That was the probl

Check your chainrings. That was the problem I had, once. Replaced the chain. Replaced the cassette. Finally took it into the shop. Head mechanic: "did no one look at your chainrings?" Bleriot's chainrings (13500+ mi) are starting to look suspect, but nothing is skipping... yet. Lynne On Apr

If it is the smallest cog only, then the stiff link hypothesis has a point in its favor, as the stiff link will be most obvious on the smallest cog, which has the tightest curvature. You can generally buy a small cog for your cassette if it turns out to be worn. Seems unlikely, because most peo

Only skipping in smallest cog makes me think it is a deraileur adjustment, maybe they knocked it out of whack a bit on the install. Did you try adjusting the tension back there? I dont know your level of expertise but if you havent done this kind of thing before just remember to go slow and make s

More detail - the chain and cassette were new last May from Rivendell. I've ridden about 2700 miles and I just learned about keeping the chain clean so I understood I needed a new chain. The new chain does have a master link. If the cassette is worn, do I replace the whole thing? I've only noti

I agree. Both of those answers are probably the two most likely suspects. Your old chain and your cassette wore together, and when you put the new chain on, it revealed the wear in the cassette that was hidden before. -- You received this message because you are subscribed to the Google Groups "R

Hi Pam, I'd maybe take a look at your cogs and chainrings (if you haven't replaced those too), and make sure that the teeth aren't too worn.You'll know if the teeth end in sharp points like a shark fin. Matt On Sunday, April 15, 2012 8:31:56 PM UTC-4, pam wrote: > > I just got a new
