  • Adie 3/8" Stabiliser Extender Bolts is rated 4.6 out of 5 by 5.
    Rated 5 out of 5 by from Just what I needed I was about to put stabilisers on my son's new bike for Christmas. It was 23rd Dec in the evening. The axles were not long enough and I was panicing! I looked on Halford's site and saw these, used the 1 hour pick up and then went and got them. They extended axles perfectly and I was able to put stabilisers on. We went on bike ride Christmas day as planned! Brilliant product.

    Rated 5 out of 5 by from Simple solution to a tricky problem! Daughter's bike was delivered with no stabilisers fitted, despite being advertised with them (not Halfords, I hasten to add!). Pretty quickly it became obvious that there wasn't room on the thread of the rear axle to fit the bolts that the stabilisers needed to be secure. Faced with a) returning the bike to the online shop and disappointing a 4 year-old, b) replacing the entire rear axle, with all the fiddly bearings, etc, or c), trying these out. Went for c, obviously! These were fitted easily and worked a treat. Remove old bolts, replace with these, add stabilisers, put old bolts back on the end. Job done, minimum fuss. Check you're buying the right size though, as axles (and consequently these bolts) come in two thicknesses. Make sure they're tight enough, but not so tight they strip the thread. Short version = Recommended.

    Rated 5 out of 5 by from Eaxctly what I needed Perfect for allowing me to put stabilisers on my son's 20" wheels. Though with these extenders it leaves it so the support bars do not sit right on the back wheel bars so I jus put the stabilisers on without these bars.

    Rated 4 out of 5 by from Make sure you get the right size! These extenders did the job very well, enabling me to fit stabilisers on my daughter's bike. There are 2 things to be aware of though: 1) no washers are supplied - in my case, washers were essential so I had to go out and by some separately. 2) there are 2 different sizes, but the packets look the same, and you can't tell by looking at the product so make sure you check the label and get the right one (a 3/8 wheel nut will not fit on a 10mm extender).

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.
