Surly 1×1 belt drive
I'll update when it wears out!Posted 7 years ago
The guy who broke Mark Beaumont's round the world record apparently did it on a bike with one of these belts and a Rohloff. Changed the belt once in 18,000 miles.
Don't think I'll get 9,000 miles out of mine when using it in Scottish mud, but I'm hoping it will last a while.
I've just been out for a lovely evening ride on my recently modified Surly 1×1.Posted 7 years ago
It has taken a bit of messing about to get everything working as it should, but now it's running very smoothly!
Here are a few photos.
Frame modification to allow the belt to be installed was done by Steven Shand, who also supplied the belt and pulleys. I still need to get round to painting the bare steel of the frame!
You've obviously spent a lot of time, effort and money on this, so please don't take this the wrong way (I'm, genuinely curious), but what exactly is the benefit of a belt drive? Apart from keeping your right trouser leg clean of course? 😀
I've got a 1×1 myself – great bike which will probably outlast me, I don't doubt that the belt drive will last ages, but I run a SRAM PC1 chain on mine which also last ages, costs buttons and takes about 5 minutes to replace.
Given that belt drives can only be used on singlespeed or hub gears, which by their nature are pretty reliable anyway, I really don't see what the advantage is.Posted 7 years ago
Is that really it?…I'm thinking a couple of minutes to oil / clean a singlespeed chain every so often (not very often in my case, admittedly)…A few quid and about 5 minutes to change a chain every few hundred miles compared to cost / time / effort to chop the frame and install belt drive.
That's not to mention the hassle of changing tyres and tubes which I'm assuming is a real faff.
Sorry, but it just doesn't seem to add up… unless of course you just really really want one, in which case that's fine! 😀Posted 7 years agollamaMember
I assume other benefits are its quieter and you don't wear out the chainring or sprocket
What about stretch?
What about weight? I'm guessing the belt is less than a chain but what about the chainring and sprocket? They look heavier
How will it 'go'? will the notches just wear out of will is suddenly snap?
I'm guessing carrying a spare is no big deal
edit: looks lile less hassle for changing a tyre cos you won't get crappy oil all over your handsPosted 7 years ago
To those who ask why…Posted 7 years ago
I don't know yet!
By next spring I might know. A winter of grit, muck and filth will either wreck the belt and pulleys or have little impact. If it's the latter then I will be happy and will probably convert my other singlespeed. If it's the former I'll go back to chains and write the project off as an interesting but expensive experiment.
Weight wise the pulleys are probably about the same or slightly ligher than an aluminium chainring and a steel sprocket. The belt is much ligher than a chain.
According to the manufacturer the belts don't stretch at all. I imagine that when it's worn out the belt may start to 'ratchet' or jump teeth. Should certainly never snap unless it's mistreated.
It is noticably quieter than a chain and I do really like not having grease on my calves, clothes, car and carpets.
Changing tyres/tubes is no different to on any other singlespeed with horizontal dropouts and a chain tug.
The silence of a belt drive single speed bike is sublime.
That alone makes it worthwhile to me 🙂
You get to see all sorts of wildlife you don't normally see.
All the other advantages are well documented, but the weight weenie in me also appreciates the loss of half a pound or so.
Here's the weight comparison.
BTW a chainbreaker tool is heavier than a spare belt if you are the sort to worry about drivetrain breakages.Posted 7 years ago
BTW if you have a frame with flat dropouts, you can do the frame split yourself. No need for fancy connectors. Many On-Ones would suit this purpose. I have done a number of conversions.

Mr Shand charged 95 euros for the join. Got the belt drive kit from him too. (Although he's in Scotland he prices these conversions in Euros because he has to pay for the components in Euros)Posted 7 years ago
As Epicyclo says you can do it in a more diy fashion by sawing through the dropout and bolting a plate on. I didn't fancy this, so went with the seatstay join.
