Do you have these in smaller diameters?
10 Jul 2019
If not, when are you getting them in or where else in the UK can I get them? I need these to attach my Old Man Mountain rack to the rear stays on my Trek Domane.
Hi, our part number 5058 come in various diameters. They might be suitable. Thanks 15/07/2019
Choosing correct size
12 Sep 2018
The Suntour NRX D LO suspension fork I want to fit these on is 37mm diameter. Do you think the 35mm size would be best, or the 40mm with some packing (rubber pond liner!) under the clamp.
Its to fit a Blackburn Outpost front rack to the forks.
thanks for your help.
Hi, go for the 40mm with some extra rubber packing. Thanks
Blade-Style Fork
06 Sep 2016
Hi there,

I have blade-style shaped forks which are 100mm in circumference, is it possible to get these any bigger to make them fit?


Unfortunately there is nothing we have to fit to a bladed fork of those dimensions, you would probably be best contacting a building supplies company as they should have plenty of P-clips in a range of sizes.

Hi,Will The 40Mm Size Fit Suspension Forks.
19 Oct 2014
Hi, i want to fit mudguards on my mtb over winter and these clips look just the thing i am looking for,do you think the 40mm size will fit the suntour suspension forks on my voodoo as there is no weight in the full guards i want to fit and the fork brace is already drilled and threaded as is the rear of the frame all the eyelets are there, a rough measure of the fork leg across is about 40mm wide,thanks for your help Mark.

The 40mm option is designed for use with suspension forks, but unfortunately I have no way of knowing for definite if it will fit your forks or not. If you do not have any callipers to measure the diameter accurately, use a piece of string or similar to measure the circumference then divide that number by 3.14 to give you the diameter. It doesn't have to be exactly 40mm though as there is a few mm extra that the clamp can be stretched or tightened to accommodate.

Two Clamps For The Price?
17 Feb 2014
Just received my order from you, thanks...an Old Man Mountain Sherpa rack, but I now need the two clamps which OMM recommend for forks without braze ons. So just wondering if I get one or two clamps for £4.99.

These are supplied as pairs.
