Niner Air9 MTB

Due to buying a new bike I'm selling my Niner.
It's a 2014 Niner Air 9 alloy in a large, it's in great condition but as you'd expect it has one or two marks from use including some cable rub on the headtube. The frame will run geared as it currently is or singlespeed with an EBB fitted.
The full spec is as follows:

Niner Air 9 alloy frame - large
Niner carbon QR fork - 1 1/8" steerer fitted with Hope tapered steerer adaptor
Niner RDO carbon bars and seatpost
Hope Hoops built with Crest rims
SRAM XX1 carbon chains with 32t chainring
SLX shifter
XT Shadow+ rear mech
XT 11/32 cassette
Hope Tech 3 X2 brakes
Hope floating rotors front and rear
XT SPD pedals
Wheel Manufacturing PF30 bottom bracket
Tubeless Specialized Ground Control and Purgatory tyres
I'm looking for £850 ono for the bike as it is.

If you would prefer it singlespeed, I could do it built up as the spec above but with a Problem Solvers EBB, Shimano SLX cranks running an Absolute Black 34t chainring, KMX Z610 chain and 17t Andel cog.
I'd do it for £700 ono for it built singlespeed.

As you can see from the pictures, everything's in great condition, it's a great bike that's ready to race if that's what you're looking for. If you want any further pictures, give me a shout and I can sort them out.

Collection would be preferred from West London but I could deliver or meet up within a reasonable distance.

I'd prefer to sell it complete but would also consider splitting the bike.

lovely bike, and a bargain GLWS

Thanks James.

Even more of a bargain now as I've dropped the price by £50!

i do not need another MTB right now!

You can never have too many!

Unless, like me, you've ran out of space to store more bikes :-)

This, and I dont want duplicate bikes and already have a lynskey 29er.
