A roadbike has a 130mm spacing on it.
A mountain bike has a 135mm spacing.
Since these are 26" I am guessing a 135.
Also, the front - some Boardman hubs use a 20mm axle, some use a standard axle with a QR.
If it is a Quick Release and a 135, I am interested.
http://www.wiggle.co.uk/boardman-cx-team/ this is exactly the bike I have except I changed the tyres to Panaracer road tyres. Have written to Wiggle (where I bought it) to confirm the spacing. Hope to get a reply today.
Yes, I am sorry for the confusion. I have just heard from Wiggle and they confirm they are 700c, 100mm axle length on the front wheel and 135mm on the rear. I just cannot figure out how to change the title of this classified!
