SSMTBs

I bought the Velosolo kit. Looks ok. Not ridden it yet though.

velo solo cogs are quite narrow based i think as
the surly ones have a very big foot print which will damage the free hub less

They're the same cogs according to their site:

"Andel (S*rly) Cro-Mo Singlespeed Cog

As with the Andel track cogs these are identical in manufacture to S*RLY singlespeed cogs but do not have 'S*rly' engraved and you don't get a brown header card. The same superb quality machining in heat-treated cro-mo with a wide base of 4.35mm for full support on the freehub body, especially when used with aluminium freehubs. This specific width allows these to be combined and used with 9 speed shifters too for custom set-ups (ie 2, 3, 4 speed etc).

Use with a road or mountain bike if running a splined Shimano pattern cassette hub as a singlespeed with our kits above or similar. Ideal for the 'free' side of a mountain bike fixed/free 'flip/flop' hub. Please see FAQ for set-up advice and converting to singlespeed.

Width is 3/32" so usable with any 3/32" (8 or 9 speed) or 1/8" chain. Full height teeth with no ramps and beautiful polished chrome finish. Available in sizes 14t to 21t. Latest stock does not have Andel engraved. Please see FAQ for set-up advice and converting to singlespeed."

Owning both ^, they do seem remarkably similar. Different finish and drilling is the only difference I can see.

Wish everyone would stop calling sprockets cogs

On-one's sprockets look just like Andel's.

Andel made On-One's HT2-style 144bcd cranks, so I'd guess all of OO/PX's ownbrand/"Holdsworth" toothy stuff is Andel.

Marginally less irritating than radiators being called radiators.

This looks rapid

Velosolo also ahead of you on that one: http://www.velosolo.co.uk/faq.html#d20

I miss my SSCX pompino and riding trails. And I have a pair of wheels with surly ultra new disc hub ... So, now it justify a n+1 bike.

I was wondering. Except the On One Inbred, is there any 29er SSMTB steel frame under 300€/250£ ?

I've been looking around the last couple of days for exactly this. In short, no. Keep your eye out on eBay but I find a lot off SSMTBs are only completes.
Other than that, it's an inbred.

I got my Swift complete for £350 on ebay, can't rate it highly enough

Ok, thanks :)
