    Rated 4 out of 5 by from Fits the Bill I wanted something that would allow me to monitor my progress whilst out and about getting fit. I found this when browsing and thought I'd give it a go. I'm glad I did. It gives me everything I need, from distance & speed to time out cycling. It is very easy to set up and the large digital display makes it easy to read when cycling

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.
