Use code NEWYEAR10 to get £10 off the stated price which, as far as I can tell, was already the lowest price around (albeit only by 1p). Chainreaction and wiggle are £80-ish for this.
NOTE: minimum spend for the code is £60 but plenty of tubes, puncture kits, water bottles, etc. to make the amount up.
This is for the fixed/fixed version in black - i.e. you can have a fixed cog on each side - no freewheel option, the single speed flip-flop variant is better value at winstanleys (£67).
Manufacturer details, confirms it does have a braking suraface for those that need one:http://www.halowheels.com/products/part/WHHAATWQ
