  • Rated 4 out of 5 by 2 reviewers.
    Rated 5 out of 5 by As Big as you'll get and quality too This review is all the more relevant now that the bag has done 2 of us proud on a cycle trip London-Paris (accompanied by a pair of panniers). It's well made with a secure fitting that never budged. From my fairly extensive research 10L is as big as you'll get for a saddle / seatpost bag but unlike others that I nearly bought this one is far less compartmentalised so will carry larger things. It does have velcro fixed dividers if you want, splitting it into 3 sections. It also has a useful zipped section in the lid. We had the zips up and down loads but the test will come over time as it's usually the zips on products that go first. Easy to take off and we just used the frame handle to carry although you can unvelcro the bag from the frame if you wish. Fantastic product already earned it's keep. 30 June 2015
    Rated 3 out of 5 by nice bag but unsuitable for my bike Liked the bag and the system. However as I don't have a mass of seat post showing, (about a foot), the bag was too close to the underside of the saddle.This made opening the bag awkward as it does not sit far enough out on the bracket. Returned for a refund. 17 November 2014

Some of the parts we sell here at Halfords have been reconditioned. These will carry a Refundable Deposit or an extra surcharge amount. When you add one of these reconditioned items to your basket, we'll add this extra cost automatically.

Once you've sent us your old item we'll check it over, and then refund you the full surcharge as long as everything is ok.

Before you return your old unit please make sure it's in re-serviceable condition. So if you're returning caliper casings, you'll need to double check they aren't badly damaged or broken. If the part you've sent is found to be unserviceable, we reserve the right not to refund the surcharge.

Please note that if you're returning your old unit to our National Returns Centre then this will be at your own expense.
