I've got a black one with U-Turn Revs, not sure of the weight but I'd estimate it to be less than 24lb.

I think that it's excellent to ride – it feels really stable on the downs, with the forks wound down it climbs well and I reckon it looks ace too. I went from FS to this and it doesn't beat you up at all – I completed the Kielder 100 on it, albeit in a rubbish time!

The finish does scratch easily if that sort of thing bothers you and the headtube seemed to pinch the top headset cup making headset fitting a massive pain but it was only £399. Overall I'm very very happy with it.

If you're around Afan and want to try a 16" frame then drop me a line.

Very impressed with mine,it a big improvement on the 853 inbred it replaced. Running with 130mm Talas. Very stable descending and feels good climbing wound down to 110mm. If you are thinking of getting Sektors I'd get the U turn versions

Yep it would be too small but you're welcome to give it a go and have a close look at the frame before ordering one.

Still good value at £599 IMO, glad I got mine for £399 tho :D. Pretty sure if you speak to them before ordering you could specify a different fork. Saying that I run a 9mm fork with an RWS and it feels pretty stiff.

Yes for pre orders, they did red white and blue 16" and 20" on pre order too but not 18"

i would say so i am 5ft 10 and have a medium it fits perfect. really nice bike to ride climb's great too. mine come in at 24.8 pounds built up pretty strong too.

It is built pretty light – XTR cranks, pro3/Stans wheels, X2 brakes, X0 gearing. And under 24lbs is an estimate, maybe a reasonable one if the XT build on the O-O site is 24.9lbs. It's got the kit on it from my Yeti ASR, bar the forks, and is lighter than that was – I'll have to get the luggage scales out! I'll not be too upset if it's a bit more lardy though.

So far as riding it, the rear end feels a lot stiffer than the steel On One I had.

Looks a lot better in real life than in the photos!

I’d pay £400 for one. I wouldn’t pay £600. Thats too much. Partly because it does look Fugly.

paulrockliffe I don’t see the point of building a carbon hardtail upto 30lb?!!

It is a great frame – geometry is spot on IMO. I run mine with a drop post and talas forks and it still comes in at 23.5lb. Faired well being chucked around Welsh trail centres as well as 100 mile xc ride.

Still think a full sus is more comfortable for trails like CwnCarn, Whites level, but I would need something that could climb as well as a hardtail to be tempted back…For the money I have no complaints at all.

I’m 6ft and wear 32″ inside leg jeans, the 18″ with 55mm stem is near perfect for me size wise. If I was doing it again I’d buy the carbon one at £399, but at £599 its just too close to the Ti price!

I love the frame, but I only like to have one mtb and after going back to a hardtail for the last year I have decided that I am going to have to sacrifice a bit of uphill speed and go back to a full sus for a true allrounder.

I had the Whyte 19 trail before the on one and whilst the both descend the same, the On one had it on the climbs. I dont know any other carbon frame out there that comes in close for the money? geometry is sorted so if you are after a hardtail.

@thisisnotaspoon – the 20″ is less than 20mm longer in effective top tube length, but nearly 50mm taller in seatpost tube. So if you end up running a lot of seatpost on a medium frame (18″), then the Large 20″ is probably a better bet. I am 5ft 11 with a 33″ inside leg (long legs) and a 20″ with a 70mm stem is spot on for me (xc / trail centre use), have had the 18″ before and had to run a 400mm post on the min line (not ideal), 20″ is same reach without the seatpost issues.

Oh really?

What if I told you that it was kitted out with relatively light-weight carbon finishing kit and all the weight was in the tyres, forks and brakes?

Why do you think weight is an issue at all? How much do you and all your kit weigh? What percentage of total weight is 4lbs?

If that’s your position than a deliberately heavy carbon hardtail isn’t for you. Carbon isn’t about weight, it’s about strength:weight ratio.

It’s an absolute **** hoot! It’s as fast as a hardtail can be downhill and quick enough uphill.

Why wouldn’t you want a bike like that?

Makes sense to sell it whilst its still practically brand new:

Bargain for anyone looking at buying a new frame!!

@goosander, were you kitted up? Haven’t even noticed the stand over on the 20″ so there must be ample – I am running a talas fork, normally set at 130mm. How do you find seat post height on the 18″? when I had the steel version in an 18 I was pretty much on the min line of a thomson 410mm post and as a result it squeaked and can’t be good for frame stress. I am much happier with a 20, so much so that it is the template I am using for my next purchase.

On an 18″ there is to my mind quite a lot of seat post showing, though not by some peoples standards! On my current 18″ frame there is about 25cm showing from frame to saddle rails, though I could still raise the saddle by another 8cm before exposing the min insertion mark on my 410mm seatpost.

Originally I was planning on getting the 20″ and reusing my Reba’s on it since I currently don’t do much technical stuff on the HT, but have since decided to make the 456 a trail centre machine as I’m fed up of pedalling the FS bike up hill. The 20″ may have been OK with shorter travel forks, but there was no standover at all with long travel forks on it.
