STILL NO BIKE.
I've lost all respect for Halfords now.
Picked up the bike from them, thought I would give it a quick ride around the car park before I put it in the car. Turns out the brakes don't work. I would be doing a slowish ride around the car park, slam the front or back brake on (they're discs) and it would stop me....eventually...maybe after 10-12~feet of holding the brake on full.
Had to leave it there for the mechanic to look at it in the morning, i've told them it's an absolute joke. I'll be complaining tomorrow.
On top of that the bike felt huge. It could just be because i've never sat on a road bike/cross bike before and they didn't even attempt to set it up for my height/reach.
Its a 57.5cm frame. I've checked online and it does say for 180-185cm height (im 184) you should go for a 57cm cyclocross frame, maybe a size smaller for a pure road bike.
I think maybe my seat was too high, it did feel a little stretched when holding onto the top of the handle bars, then when I held the underneath part it just felt unsafe!
