Singlespeed conversion kit – any recommended?
I am converting my old hybrid commuter bike to single speed. So far I’ve removed the surplus shifter and rings from the front and locked the rear derailleur in to a suitable gear on the rear, I’ve tested the ratios and I’m ready to take the plunge buying proper parts.
Is there a recommended single speed ‘kit’ people go for? I’ve seen the DMR kit (spacers, single 16T ring and tensioner) for 25 quid which is very tempting. Is there anything any better?
I know you can get the cassette spacers from lots of places (10 quid) and a single Shimano rear ring (5 quid), I’m just not sure which is the better tensioner.
Thanks in advance!Posted 2 months agowhitestoneMember
Charlie the Bikemonger has some SS kits but they are a bit pricier than the DMR one. My frame previously had an Alfine hub so it used horizontal drop outs so I didn’t need a tensioner – made things much simpler. Some people say that having a tensioner that pushes up rather than down is better since it wraps the chain around the cog better.
It’s worth having a couple of cassette spacers around just in case the spacer kit doesn’t quite cover the free hub – On-One I’m looking at you!Posted 2 months ago
i fitted the DMR kit to my Merida – it did the puffer with no issues after that was the cheapest i found at wiggle for 25 quid.
i much prefer a fixed tensioner – never found it to be an issue to run pushing up or pushing down when your running kit that isnt ****- as shit wears out i find pushing up to be better – but really if you just got a new chain chain ring and cog it would be a far better solution at this point.Posted 2 months agootsdrMember
I prefer spring-loaded tensioners (Surly Singleator, Rohloff DH), you don’t have to fiddle with them as the chain wears out; also, they take out any eccentricity in the system and don’t allow the chain to rattle.
l.e. If you have an alloy freehub body you might want a wide-base cog like the On-One Groove Armada.Posted 2 months ago
rohloff dh is a good bit of kit if not heavy mind
singulator spring was shit- could not tension it enough to stop it jumping around over bumps/banging off the stay and holding the chain on the ring. might as well have left the deraileur on. its still in my spares box.
fixed tensioner rarely needs adjusted .Posted 2 months agothisisnotaspoonMember
I wouldn’t worry too much about the pushing up or down issue, the forces involved are more than capable of lifting the chain off a push up tensioner, even an un-sprung one. And push-up tensioners don’t play nicely with every chainstay design.
Do get propper 3/32 SS parts though, they last longer and won’t collaborate with your stem to give you a vasectomy.
My setup:Posted 2 months ago
Chain – KMC Z610
Sprocket – On-One Groove Armada
Chainring – On-one Stainless
Spacers – assorted (I even 3D printed some orange/black tiger stripe ones!)
Tensioner – On-One sprung doofer, and a surly singulator (both pushing down), never had a problem with either.downhillfastMember
Think I used a chain tensioner from On-One, push down variety, never had any issues with it.Posted 2 months ago
Or just use your mech.
Currently have On-One stainless chainring, and a standard 21T cog taken from a cassette (I’ll be getting a proper SS cog soon) whilst I find a ratio I’m happy with.
If you break apart an old cassette you can use the plastic spacers to put on your cassette and help get the chainline spot on.
Velosolo do some nice cassette spacers and other bits.
I’d get all 3/32 SS parts, and the KMC Z610 chsin is very good, doesn’t seem to stretch as much as others.teamslugSubscriber
I convert my cannondale f29 using a gusset singlespeed kit and a gusset squire tensioner. Comes with 2 springs for push or pull. Running 32/16 with a narrow wide and 9 speed chain, tensioner is pushing down. Never skipped or dropped. Great bit of kit for not much money.Posted 2 months agotimberMember
I got the superstar kit when I singlespeeded one of my bikes for a while, has a wide base to the sprocket to protect the freehub (as already mentioned somewhere I think).Posted 2 months ago
Now I’m back to my regular singlespeed setup, it’s 3/32 BMX freewheel, steel front ring and a chain with a half-link added to avoid having to run a tensioner. Easier wheel in/out and just looks cleaner.
I can report some success. Kit: A2Z rear single speed kit with 16T, 4-Jeri sprung tensioner. Original 38T front chain-ring and 9sp chain.
I originally set it up for 18T but found the chain jumping under moderate pressure when I fitted the 16T, so had to shorten the chain to suit. Unfortunate, as I wanted to swap between the two gears freely.
First commute on it this morning, something has a slight vibration and noise which I suspect is the bearingless jockey wheel on the tensioner. But pretty happy with how easy it was.Posted 2 months ago
