The Problem Solvers Sheldon Fender Nut was designed to replace the standard brake nut and allow convenient fender (mudguard) mounting on steel and aluminium road frames and forks.

Product Uses:

Essentially, this is a long brake nut for road forks, as it allows the road brake nut to thread into it for brake mounting. But, it also has threading inside so that a fender (mudguard) mounting bolt can be threaded into the back of the fork. Sheldon Fender Nuts are supplied as a pair: 32mm length for front fork crowns, 10mm length for rear bridge.The fender nut will work with all steel and aluminum frames and forks; it also will work with some carbon forks, but check first. It will not work with forks requiring an extended brake nut or a narrow brake nut (such as Reynolds). Technical details: PS Sheldon Fender Nut is a standard 6mm brake nut with longer internal threading and an extension on the back side for a 6mm mounting bolt
Simply install your brake as you would normally then with a 6mm bolt (not supplied), mount the fender (Mudguard) to the back side of the nut and to your fork or frame

Useful for fixing mudguards on bikes with tight clearances

ProsAdds more convenient mudguard fixings to bikes without them
I have a couple of bikes with tight clearances for mudguards and these are very useful. By moving the bracket from the brake bolt to the rear of the fork or brake bridge, this gets the fixing out from under the arch and improves clearance. Also makes it easier to remove guards in summer if you want to, as you don't need to remove the brakes. The long front bolt can easily be cut to length with a hacksaw. You'll need M6 bolts to fix your mudguards.

Consexpensive. no bolts
Prosextra clearance. Leave brakes in situ if removing guards
The selling point for these seems to be that you can fit brakes and guards independently which you can. As these are for my winter bike that didn't attract me as I leave the guards on all year. However what they did is give more clearance because the bracket is no longer under the forks. This extra clearance has stopped guards getting clogged with mud which is exactly why I bought them. I think they're expensive for what they are and should come with the bolts for the guards but would buy them again

Can you recommend which specific bolt I need to buy, to attach to the end?

(Planning to attach a steering stabiliser to my recessed brake nut)
An M6 bolt is needed- we cannot be specific as you may want a button or socket head depending on the clearance.

For the front 13mm is too short, but 32mm too long. Is it ok to cut the 32mm down to size?
20 Sep 2019
Yes you could cut these to size.

Hi my recessd nut which i use with ultegra brakes in carbon fork is 28mm will these bolts work?
Hi there,

Yes the 32mm version should work.

Is the head the same outer diameter as a recessed nut?
18 Jan 2018
I have carbon forks with a recessed brake nut. For the Sheldon Fender nut to work, it would have to sit inside the fork.

Does the outer diameter of the head allow this?

Hi there,

Yes it should sit snug into the back of the fork.

For The Front 32Mm Can You Please Tell Me The Head And Shank Lengths Thanks
29 Apr 2017

The shaft length is the 32mm and the head is an additional 10.5mm.
