ConsA little pricey for the size and quality, but I guess thats the scarcity value
ProsDecent rim in a hard to find rim size
Used these to build onto old Kingpin hubs and improve braking. No problems and look good.

Can I use 22 inch BMX tires on these rims?
29 Jul 2021
The rims are 451 and 22 inch BMX wheels are 457. That's pretty close! Is there any reason the combination shouldn't work?

457mm tyres will not sit on the rims and with even a low pressure will blow off the rims.
We do NOT recommend using anything but the correct size.

Rims and spokes for Raleigh Shopper
23 May 2021
I want to upgrade the front wheels of a couple of 19702 Raleigh Shoppers from the chrome originals to alloy to improve the braking.

I guess your Sun CR18 20" 451 ABT Rim - Polished Silver - 28 Hole will work.

However, I'm not sure what spokes I will need. One wheel has a dyno hub.

The spokes on the non-dyno side measure 220mm.

The short spokes on the dyno side measure 195mm

The pitch circle diameter (PCD) of the spoke holes on the dyno hub is 102mm.

The PCD of the spoke holes on the standard hub is 43mm.

Could you advise.
We cannot confirm spoke lengths unless we sell both hub and rim,

Please can you advise spoke lengths for standard Raleigh front hub and Rear AW3 with these rims?
03 Sep 2018
I have a 70s Raleigh Stowaway with 451 wheels, are you able to advise spoke lengths for standard Raleigh front hub and Rear AW3 with these rims? Also, I’ve had a few rear spokes break, are there stronger spokes, or would washers help? Many thanks
Hi there,

Without having dimensions of your hub it is very hard to say what length you will need I'm afraid. If you do manage to get some dimensions, please email us with them and we will be able to help you.

Will these fit my Raleigh Shopper stowaway folding bike?
31 Jul 2018
The name Stowaway has been brought back, if you mean the vintage one from the 70's and 80's yes, I believe they did have 32-451 tyres, so yes.
Is this rim compatible with your Schwalbe One 20-451 Folding Tyre?

Hi there,

This rim would be suitable.

Replace Weinmanntek Tm19 28-451 (20" 1 1/8).
22 Mar 2017
My current rim is Weinmanntek TM19 28-451 (20" 1 1/8). Can I replace TM19 with CR18?

You will most likely require different spokes as the length will probably be different but otherwise you should be fine to use this CR18 rim as a replacement.

Will This Rim Work With 37 – 451 (20" X 1 3/8") Tires?
16 Nov 2015

This rim should be absolutely fine for use with those tyres.

Is This Rim Drilled For Presta Or Schrader Valve? Thanks
12 Oct 2015

This rim is drilled for Presta valves but we can drill them out for Schrader valves upon request.

06 Mar 2015
