The Ultimate Mid-Drive Chain Care Thread

[PedalUma]

Sometimes I buy generic or not top brands. I purchased a box of sintered brake pads this week. 25 pairs with pins and stainless springs was $65. It came with some bonus parts. No one will know or care that they do not have a logo. Just that they stop very well. SRAM or Shimano would be $20 per pair at a bike shop. $20x25=$500. MicroShift makes a trigger shifter for Shimano IGH that is nicer than Shimano's and costs like $15 bucks. It is a big improvement over a twist shift.

Good to know, I guess I shouldn't have cheaped out going with the lowest price on eBay. Steep and cheap which is a reputable seller had it for a buck more than eBay but I didn't want to pay shipping so went the eBay route.

Here's a video showing the play in the cassette that I noticed.

Edit: just tightened up the cassette and the play is gone. I guess we'll see if this fixes my skipping issues. My torque wrench didn't fit the cassette tool so after hand tightening I applied wrench from 3:00 position to about 5:00 until it took a bit of force to tighten another notch. Hopefully I did it right and didn't tighten too much. Shrug.

Gudentight is good enough. I've never used a torque wrench on a cassette lockring.

I(dont use a torque on it jsut put a fair amount of tightening till it feels like it wont move anymore.

Well, tightening up the cassette didn't fix my issue, so I think I probably just needed a new cassette. Derailleur hanger angle looks good. The mechanic that came out to fix my broken spoke did adjust my b screw but I can't imagine that or barrel tension would be the issue since it's only skipping in the smallest cog under load. I guess I'll wait and see if a new cassette solves things when it arrives.

The thing to consider is the smallest cog may only have 5 teeth in contact with the chain at a time because it has 11 teeth. But with a 32 cog about 15 teeth are in contact with the chain. The load is better distributed; less concentrated. Sometimes you can just buy an 11-t cog, just replacing that.
