Problem Solvers Sheldon Fender Nuts - 10 & 13 mm - Per Pair

I recommend this product

Nicely manufactured - but only comes in short and really long for the front. Shorter enlarged part than others may be what you need in tight spaces or to conventionally mount mudguards.

First issue - before a club-mate put me onto these extended nuts I had installed the front mudguard bracket in front of the fork with spacers, so the top edge of the bracket did not foul the lower headset bearing. Not ideal as this not only moved the mudguard forward from the ideal position but also moved the caliper further away from the fork. It just didn't look right.
Second issue - I no longer need a third hand to align the mudguard and caliper with the front wheel as these operations can now be done separately.
Comment - although other reviewers think these nuts are expensive, I would pay extra for the M6 mudguard bolts to be included as I had to spend time sourcing suitable bolts.

Works as described for my vintage bicycle. Very neat solution. I used brake pad mounting bolts for the mudguard fastening

These work perfectly. Nicely made, and very good quality. Very expensive, but you get a nice bit of laser-engraving on the side. You'll need some bolts for the ends, though.

I initially fitted flimsy and ultimately annoying clip on mudguards which I recommend people should avoid and felt a better solution was required, these fender nuts proved to be the answer. They allow secure mounting without interfering with the brake assembly as is often the case when fitting mudguards. These fender nuts are a great idea from the late cycling guru Sheldon Brown.

Excellent product and excellent service.

A simple solution to an annoying problem. For the price I'd've hoped that the required 6mm bolts and some washers for actually fixing the mudguards would have been included, to save me rummaging around in my old biscuit tin of nuts'n'bolts. Still, I now have neatly mounted mudguards on both my wife's and my own bikes so I'm happy.

I wanted to fit 'proper' mudguards to my racing bike, as it has clearance for them, as I don't like the flimsy clip on versions, which don't provide much coverage. But I could not fit the guard behind the fork at the front because the caliper bolt was not long enough and in quite the right position. These widgets replace that bolt, and allow you to screw the mudguard into the back of the bolt. Pricey, but effective. I will know keep dry in winter.
