Last summer, I did a mountain bike ride with a friend who is a very talented rider, and who had recently converted to 1×10.
He dropped his chain with great frequency.
Based upon that experience, one of my goals was to have a good plan for chain retention when I went 1×10 on the Superfish. The SRAM Type 2 rear derailleur was step 1 of that plan. Step 2 was some form of chain retention device. I looked at a bunch of different ones…I really wanted to use a Paul seatpost mounted one, but couldn’t get it to fit quite right. I looked at E-13 as well. I looked at the MRP mountain bike chain retention device, but really didn’t like the long, hinky bracket that it came with. (Of note, with a PF30 bb and no ISCG tabs, mounting a chain retention device on a Spearfish is challenging). I think the MRP 1x mountain guide would work fine, but I wanted more streamlined…more elegant. So I decided to try the 1x cyclocross guide.
The seatpost clamp is aluminum; the guide is some sorta fancy-pants plastic.
Chainline is good in all 10 gears. Here’s the bad news…it didn’t quite clear the chain in stock build. Accordingly, I had to make up a little spacer and mount it between the clamp and retention loop.
If you look at the right side of the picture, you can see a black spacer between the 2 parts. It also thus required a longer allen screw. Time will tell if this is a successful gambit or not. It seems relatively sturdy, but we’ll see.
Running 1×10, I also wanted to be able to dump a lot of gears quickly. That brought on the thought of throwing on a gripshifter. A coupl’a trades later, and I had an XX gripshifter.
I’m not sure what grips I’m going to run yet.
I’m also not sure what I think about the mounting of the shifter yet…there’s not a lot of clearance for the brake lever, with it mounted in optimal 1-finger braking position.
We’ll get some miles on the setup, and report back.
