After last weeks discussion re Alfine Hubs I decided to give it a go and ordered one on Monday to be built up on some nice Stans Rims.
About to order some Middleburn cranks and have a quick question:
I have ordered the 22t Nexus sprocket for the back and am starting with a 30T middleburn on the front. Can I run a 9sp chain with this combination or do I need to go to singlespeed???
Would prefer to use the 9sp chain if poss so I can use old chains off the Yeti / same splitlinks etc.
Thanks in advance 🙂
I'm no expert, but I can't see any reason why not. You won't get chainsuck....
Although it has to be said I'd be tempted to run something cheap but wider. SRAM 7/8sp chains can be had for £6-ish, and that's my singlespeed chain of choice. IIRC they come with link as well. Maybe try one of those?
I run a 9 spd with mine and it's fine. It means I can use the same spare bits as my other bikes.
I found the single speed chain would run very close to the chain guidey bits on the hub and sprocket and make an annoying rubbing noise at times.
Thanks
Keep the "low maintenance" theme going...

Got one on my SS hackbike. It's been outside for over a year now - chain still looks (and runs) great.
What Hicksy said about the cable guide/chain proximity is true. I use a 9spd and there's only a very small gap (with the guide angled at 45 degrees ish). I use 20T with Middleburn 29T on the front.
8 speed chain
I have nine speed on mine so as to have spare parts common across all my bikes, No issues yet.
well shimano techdocs only lists shim 9 speed chains as part of the alfine group..
Comfort > Alfine
also alfine chainset docs states 9-7 speed chain
reckon 9 speed is the way to go
I use 9 speed chains on mine, usually the old ones off my other bike.
30x22 sounds a bit low unless you live in the alps, I run 32x18 on my 29er and it gets a bit spinny
As Mark says, 30x22 seems very low, although I don't know where you ride! 34x20 on mine, the low gear on that is low enough for me, and I ain't fit. I'll say that after messing with the circlip which holds the sprocket on, changing rings is easier! 9sp chain ok though 🙂
9spd, 8spd, singlespeed, it matters not what chain you use... Though obviously 1/8th inch singlespeed chains are likely to be a lot stronger than a 9speed chain that is designed to shift over a casette smoothly all day long!
34x22 on my Alfined 29er. 30x22 is a tad low, especially if it's on a normal 26" wheeled bike. I recommend a 32x20, or even 34x20 as a starter gear on a 26" bike, 32x22 or 34x22 as a starter gear on a 29er (as 29er wheels are approx 10% larger in diameter).
Drop me an email if you want a gear calculator...
I use a track chain on mine. Its about 18 months old now, and hasn't stretched at all.
