I recommend this product
ConsNot double eyelets, box section quite shallow
ProsDecent 406 rim, single eyelets
I have just measured the ERD of two of these rims and found the value to be 394 mm (not 397 as stated in the description above).
SJS Customer Service:
Hello & thank you for your enquiry.
I have just referred this to our wheel builder who has referred to his data & provided a revised measure at 392 mm.
Thank you for bring the sizing issue to our attention, online data will be amended accordingly.
Hope this helps.
Kind regards, PC 24/5/23.

ProsGood value, solid build quality
Good solid double walled rim. Used the 36 spoke option on an old e.bike hub that only had a single wall rim, and it was carrying some weight too lol. Trued up well.

Solid, strong rim. Will be used as a front wheel in my recumbent. Can't comment on the longevity as I only have it for 2 weeks.

ProsStrong rim at a good price
The first rim on my tandem lasted 6 months before the eyelets started pulling out. This rim has done 2 years and 2000 miles on roads and trails - no problems

Had these rims built into a wheel-set by sjs to bring an old moulton apb back to life. Wheels arrived within a week. First class service and made into really nice wheels.

ConsLike any alloy rim, it eventually wears out
ProsStrong, well-made, easy to true
Bought this to replace an identical rim on my Moulton TSR, which has lasted about 8,000km of hard commuting and some training, in all weathers. I could possibly have got a bit more out of the old one but didn't want it to fail suddenly. Well made, easy to true. SJS did well - it arrived here in Australia in under a week.
Nice Rim

ConsNone
ProsStrong, good looking,
This with a Hope hub has built into a nice strong wheel, for my DiscBrake project on my Moulton. I wish that I'd known about Spoke Length Spreadsheets on the net and could have quickly worked out which spokes to order at the same time, saving myself the small postage add on. It was easy to build the wheel, but was not a quick job, mainly because of threading the short strong spokes and not letting the ends scratch the rim. There was no problem putting a Marathon Plus on by hand. Have finished with a lovely strong wheel.

Schrader valve

Hello, do you have the 36 hole version that is suitable for Schrader valves please?
Sadly they are not available as a Schrader option, most people will simply drill the Presta hole out to fit Schrader. SK 26/01/24

Hi, please can you confirm whether your current stock (Mar 23) has presta or schrader valve drilling. Many thanks.
Hi, they are drilled for presta. Thanks
I still have questions about colors
By

The photo of this rim looks polished silver, but is it really polished silver?
Last time I bought 28H of the rims, it was polished silver.
Is 32H the same color as 28H?
In this size, they are a slightly polished finish.

By

Hi I have been wondering is it suitable for e-bikes as they will need 13G spokes for the rear wheel and also can you confirm that ERD is 397
Thanks
These rims are not officially rated for E-Bikes, We do not have an ERD on hand we can supply sadly.

Thank you

Original thickness?
By
14 Oct 2019
Have been using these rims on my Moulton TSR for a while and done 4,100miles on them.

Nice shiny silver rims!

However, they are showing signs or wear. Measuring mine, the rear one is down to 1.1mm

What thickness were they when new?
If I knew that figure, I would know when they were to be replaced.

Thanks, Mick.
Hi
Thank you for your enquiry, the approximate rim wall thickness on this rim is 3mm.

Size Confirmation
By

Hey Guys,

Hope you're well. Im looking for a set of rims that are 20" x 1.75 in 32h and wanted to make sure that these are what I need.

https://www.sjscycles.co.uk/rims-tape/28-sun-cr18-20in-406-abt-rim-silver/

Can you confirm and ill place an order?

I also need a set of 24x1.75 32h if you have some.

Thanks in advance,

Mar
Do you know the actual 20" and 24" sizing? within 20" there is 406mm, 438mm and 451mm and 24" has 507mm and 520mm.

Without this we could not confirm!

Thanks - 10/05/19
Do you have experiance of building these into wheels?
By
20 Sep 2018
If so, can you do it? What would you charge? I'm thinking of a front schmidt dynamo, and a rear, robust hub with a 10 gear cassette.
Yes, we have built many many wheels with CR18 rims, our wheel building packages can be seen here - https://www.sjscycles.co.uk/wheel-build/

New rims for HP-Velotech. Grasshopper fx?
By
22 Apr 2018
My Grasshopper recumbent from ca. 2007 will soon need new rims (has V-Brakes). Do you think this rim with 32 holes will fit with the same size of spokes as the original ones? The old rims are Alexrims, but I am not able to read which type. I normally use Marathon 35-406 or 47-406 tubes.
Or do you have other suggestions?

Thanks in advance.
Johannes (DK)
Hi there,

It is highly unlikely you will be able to re use the spokes unless using the exact same rim. After 11 years of use we would recommend using new spokes regardless.

Thanks

By

Are your 20 inch cr18 rims Schrader or Presta? Can I fit both a 1.75 Marathon Plus and a 35-406 20 x 1.35 Marathon?
Good question. Our CURRENT stock is presta for 28 and 36 hole but Schrader for 32h! Either of these tyres will fit.
please see extra detail

Hi I'm intending to buy a sun CR18 20inch 406 rim from you.
Can you tell me the OSB so that I can calculate the spoke size for a hub disc ( Shimano Deore M525 Disc hub )?

Hi,

This rim has 1mm of spoke offset.

Thanks.
Rubber Gromet To Plug Valve Hole
By
08 Feb 2017
Hello, I intend fitting a solid tyre onto the rim so therefore I am looking for a rubber gromet to plug the valve hole. Otherwise water will enter the rim and stagnate. I hope you can help me. Regards from Bernard.
Hi,

Unfortunately this is not something we would have I'm afraid. It is not something we were aware was produced. The best we can recommend is speaking to whoever you're getting the solid tyres from as they would have the best idea.

Thanks.
Valve - Presta Or Schrader
By
19 Dec 2016
I purchased four of these rims recently. They were described as 'drilled for Presta', which is what I was expecting. However, they are actually drilled for Schrader. Can you check and, if applicable, correct the product listing.
Hi, we have checked these & our description was incorrect. The description has now been changed to say drilled for Schrader. We have sent you some Mavic Valve Adapters & apologize for any inconvenience caused.
