Belt drive fixed

I had a thought that one of the best ways around the removable dropout/splitable seatstay would be to put the cog on the outside of the frame. However I couldn't come up with any sensible way of doing it which would still enable the wheel to turn.

Then I saw that Chris Boardman's Lotus does in fact have the cog on the outside of the frame:

I think this might be a good solution to the problem, though it possibly may still need a special dropout.

But that bike is a copy of a ghost bike,

is it fuck, it's just a white bike! loads of hipsters had very white bikes back when fixies were fashionable..

wind your necks in

problem is you'll have to worry about your belt getting stolen...
on the other hand it could be a good anti-theft feature: just take the belt off when you lock your bike up...

Also guess the Q factor could start to get out of hand with the cog on the outside of the dropout and everyone would be walking around like they had just got off a horse!

On a mountian bike you'd need to put the disc from the disc brakes on the outside as well. To avoid too much dishing on the rear wheel. You'd end up with a rear drop-out width witch is less than the width of your tyres. Thing is that this set-up would require special frames in the same way the current system does, so I cant really see the advantage.

I think F8 Cycles offers a fixed gear belt drive.

possibly when the strapline on their website is:

    **custom fixed, single-speed, and internal hub belt drive bicycles**

don't be a dick.

The S3X hub (they still calling it that?) is supposed to be compatible with the Gates belt cogs. That would be a nice rig. Assuming they ever offer it for sale.

Like this puppy

Right just ordered my Hope Pro II trials/SS rear hub (at last). Its a bit of a risk as the belt drive is very fussy about chainbeltline, and a standard rear cassette hub would allow more adjustment. But I dont like the idea of dishing the rear wheel for a single cog.

If I can stop myself from buying a road frame. I could have the FR-BD-SS-29er* (needs new name) finished after crimbo :)

(Fully Rigid, Belt Driven, Single Speed, 29er)

if the beltline isn't precisely accurate, surely a different bottom bracket length would be cheaper to obtain to solve the problem? or is that not an option?

I has no idea what expensive BB you're going to get actually.

The trials hubs have a stronger free-hub than the standard ProII and more engagements. So it was an easy chioce really.

Bloody good point though.

I'll be getting an external bearing BB (fifteen G by thehive). So theoretically could just space that, as well as the sprocket. Being able to play with both should get me there crosses fingers.

The trials hubs are damn nice.

Are the SS hope trials hubs not actually 6 speed cassettes like the chris king SS hubs? If so this should give you enough room for sorting the beltline.

Not sure on this but think its right

Yep, you can fit up to 6 cogs on them, which keeps them trials legal. But I#m not going to pretend I know much about this. Still works out more flexible with the standard hub though.

Any more progress on the belt drive?

The idea is brilliant and I'm sure it'll catch on, but there are limited rings and cogs available so you can't get all the gear sizes you amy want.

only at the moment

All we need now is S3X that is compatable with the belt drive cogs.

Like the idea of the cog on the poutside of the frame as per the Lotus. However the back wheel in the Lotus was out of line with the front one, which may not be to some peoples liking. In any case if your going to the trouble of having a special frame and wheel to accommodate the cog on the outside, you may as well get a frame with a split triangle.

we used to have block chain in the past;

when the new chain was made, it soon got replaced by the superior one, I've no doubt that in a couple years time we'll see a variation of different version.

Some pic's of the drop-out opening mechanism on my Spot Longboard. Bloody difficult to open up TBH (happily). Its a very neat system. The plate is screwed in place, and its further held in place by the hub bolts. So it cant open while your riding, unless your rear wheel has fallen off.
