If you’ve got an Arkose 4, what do you expect a Boardman CX Pro or similar to be worth spending ~£700 on in a salary sacrifice scheme for over the Pinnacle?
Couldn’t you simply get a set of CX tyres, possibly a nice set of CX wheels and be happy?
Arkose 4 has guards for a start so I’d need to take them off, going away for a weekend I’d need to do that on a Thursday night, then put it back into commuter mode on the Sunday. Way too much hassle.
You can’t top up the value on C2W, not officially anyway. Apart from the red cables that cube looks good. Our scheme is with Halfords so planet-x is out.
As for buying a bike with cable discs, then as above I’d need shifters and a set of brakes.
