I'm not home & trying to figure out what size jump stop I need to for the front sprocket; I don't know what size the tube is. Can anyone help, or point me to something they've used?

...this is my bike, but I've configured as a 1x9. LINK

Thanks!

The Jump Stop should be whatever size your front derailleur clamp was, but since that bike didn't use a clamp-on front derailleur you'll have to measure the seat tube yourself. Is the seat tube round in the area across from the top of your middle ring?

are you talking about the N-Gear jump stop? I would not recommend it on a full suspension bike based on my experience.....it just didn't work for me.....for hard-tails the jump stop works fine....

The N-gear webpage describes how to estimate what size you need if you don't have a derailleur for reference N-Gear: Specs and Order Info.

Nevermind .. just noticed in your post that you're not with the bike.

id have to agree, something like an e13 xcx guide would be better.

love the simple sets for 1x9- I have set these up on a Nomad and an Intense 6.6 and had pretty good results- not great. These types of set ups work best on hard tails or cross bikes- just too many moving parts.

Thanks guys. The E13 XCX looks like what I need. I'll take a look later, but I had the impression that the tube is oval at that point, so I would need a BB-mounted solution like the XCX.
