Single speed gearing
32:16=2:1 so it will be somewhere in the middle.
Thought there was something about running an odd number of teeth on either chain ring or sprocket, and an even number on the other to even out chain wear? Would 34:17 not be an option?Posted 4 years ago
4ft 4in is pretty much perfect, as long as you can maintain the prerequisite facial expression…
Jokes aside, 32:16 is pretty much accepted as the norm. You can fiddle about with it for extra niche points if you like, but bear in mind that changes on the back will have a much greater impact than changes up front.Posted 4 years ago
Hi, just after a bit of advice…. I have an Orange P7 single speed & my current gearing is 34-16 & it’s just a little bit tough when riding single track…. Swinley nearly kills me! If I go bigger on the rear to an 18 I find I spin out too easily… By dropping to a 32 on the front will that take it to a mid point? & before any one say get gears thanks but I like SS!Posted 4 years ago
To be fair I probably need to change the lot…. Had the bike 6 years & nothing has been changed drive train wise…. I know I probably should have….Posted 4 years ago
Have a surly tensioner which has helped with the stretch of the chain but it hasn’t missed a beat yet & gets pushed quite hard…. Knee popping uphill sections…. Hope pro 2 hubs probably help.MidlandTrailquestsGrahamMember
Don’t quite understand the inches thing.

All you need to remember is that “changes on the back will have a much greater impact than changes up front.“, decide how great an impact you want, then make the change at the appropriate end.
That’s all there is to it.GDRSSubscriber
I used to ride around the ‘old’ swinley ‘with added fun’*TM on 32/18 – a bit spinny but helped out in the steeper bits and boggy sections……
Went to the ‘new’ swinley ‘less fun, less mud, hard shiny motorway’ *TM and I might drop back to 32/16 as it is not too testing and what ever happens you now know how many K’s you have to ride.
Sh*T – this is not about gears – I am just down about the Swinley development. Sorry.Posted 4 years ago
32:18 = 46.2″
34:18 = 49.1″
32:16 = 52″
As someone mentioned earlier, 36:18 also equals 52″, and will create less wear on components.
I seem to remember reading on Sheldon Brown™ that the “inches” measurement corresponds to the theoretical diameter of a Penny Farthing drive wheel….Posted 4 years ago40mpgSubscriber
I run 32-16 in the summer and 32-17 in the winter to make it a bit easier getting through the mud. Only just a noticeable difference.
Anyway, if you’re bothered about getting off and pushing sometimes, you’re not getting singlespeeding.
To the OP – you don’t need to change anything until the chain starts skipping over teeth, at which point some will break off. There will still be enough left to get you home. Just buy a 17 tooth sprocket for £2.99 and get out and ride.Posted 4 years ago
Just a quick update…. Was actully running a 34-15… Changed to a 16 & works well… Not too much spinning out. Thought I would try my luck & not change the whole drive train as it hasn’t been replaced in a long time (5+) years at not a single slip. Thank you for your help. Not sure what is meant by I need a some wobble but hey…Posted 4 years agopodmanMember
They’re elliptical rings to help with the “dead spot” and allow you to run a harder gear.Posted 4 years agoepicycloSubscriber

No good off road tho…,..
Waddya mean? You’d never have to bunnyhop another log… 🙂
Back to the original question – if your climbs are short then 32:16 or higher is good because you can use the speed gained on one descent to get you up the next climb.
However if you have long steep climbs be looking at 32:18-22. You can gain more speed on a long descent on an SS by freewheeling with your belly on the saddle than spinning like mad.Posted 4 years agothisisnotaspoonMember
I’ve got 34-20 (on a 29er, so close to 34-18 on a 26er) and ride Swinley and the surrounding areas a fair bit. It’s about as low as I can go, but it’s better IMO to learn to pedal at 100+ rpm and carry speed as that puts the load on the cardiovascular system rather than muscular systems.
I was actualy 5min/lap quicker at Swinley on the lower gears and feel fresh afterwards too.Posted 4 years ago
