1 X 9 chain drop FFS
How many times will this question be asked. For 1×9/10/11 you NEED:
– unramped chainring
– some kind of guide (as a minimum a top guide, I prefer something like an MRP G2 with top and bottom guides)
– the correct length chain
This will work. Honest. Any form of p*ssing around with ramped middle chainrings and inadequate chainguides will just not work… (I’ve been there and done it – quickly got madly annoyed with it and spent a bit of cash and did it properly).Posted 4 years agomunrobikerMember
Is the guide you’re using not meant for double chainring use? It won’t work at all for 1x use because it has no top guide- it’s meant to work with 2 chainrings and a front mech, which will keep the chain on up top.
You’ll need one of the top guides suggested above (the e13 ones are the best IME).Posted 4 years ago
Resurrected the old steel HT over the W/E and thought I’d have a go at this ere 1 X 9 malarky.
I removed the granny and outer rings on the triple chainset and fitted a Gamut P20 dual BB mount jobbie.
Commute in this morning confirmed very quickly that the lack of front mech and/or top retaining guide is a sure fire way to drop the chain at what seemed like every possible opportunity; – leaves on the road, clouds scudding by, you name it 🙁
If I stay with 1 X 9, what’s going to be the best bet to keep the firkin chain on? I haven’t been able to locate anyone who has Gamut’s single boomerang BB mount wotsit in stock so should I try an e.13 mount or something like Hope’s chain guide?

I guess I was being optimistically naive with what I’d cobbled together.
As this is a frankenbike bodge of old left over parts, I’m not going to do dedicated rings. I’ll grab one of the e13’s to see how tonight’s return trip fares, otherwise I might ‘revert’ back to 2 X 9.
My other bikes are pucker 2 X 10 but this is an experiment with a ‘play’ bike.Posted 4 years agoNorthwindSubscriber
I’ve found a normal unramped ring doesn’t make much difference over a shifting ring… Decent chain device or clever thick/thin ring absolutely essential. The Superstar one works OK but if you can stretch to it then it’s definitely worth going for a E13 XCX or an MRP 1X, they’re slightly better than the Superstar, but also far easier to get good results out of.Posted 4 years ago
I am sure others are available.Posted 4 years agocrankriderMember
Best thing for keeping the chain on:
Or Raceface, from the usual sources (same, little more expensive, but in stock right away)
My Works one is still awesome after a few months riding 🙂Posted 4 years agocookeaaSubscriber
-Un-ramped ring, something with a nice deep tooth profile – middleburn/RF/E13?
-Top Guide, MRP, superstar
-Shorten chain to minimum Number of links for largest sprocket (+2)
Optional ideas:Posted 4 years ago
-Lower Roller, Blackspre stinger?
-Go 1×10 just for the clutch mech?
-Posh thick/thin or XX1 type chainring?
