BOARDMAN SLR ENDURANCE DISC 9.0 £1999.99

The SLR Endurance Disc is the oldest bike here, which shows in its old-style brake mounts, previous generation Shimano Ultegra components and a 15mm RockShox front axle from a mountain bike fork. A price reduction to £1599.99 means this previously £2k bike now just scrapes into our test.
