These came with a recent bike purchase and I won't be using them anytime soon . Two what look identical pairs of rear bag's . With the following approx measurements . 15"or 38cm tall , 12" or 30cm at the top narrowing down to 7" or 18 cm at the bottom and 5" or 13cm main compartment size , with a front pocket of 11" X 8" and a side pocket of 8" X 1.5" . All zips and flaps look and work ok as do the carrying straps , only issue I can see is there are only 3 of the 4 lower mount clips included . Asking £25 posted for both PRS or £15 each pair posted to a UK address. Can be collected from nn8 Wellingborough postcode.
