A bit of a shame they don't come in chrome... none the less it does exactly what is says on the tin. It arrived when stated, well packaged and undamaged. Raising the quill stem and combining with some Mary style bars, has given me the upright riding position I wanted for my beater. I will be using SJS more in the future. Many thanks!

ProsQuality product
On holiday I was persuaded by a friend to try and ride his bike. After not being on a bike for more than 50 years I was surprised how much I enjoyed it. On return I purchased a bicycle and am enjoying the local cycle paths and byways
The only problem was leaning forward to reach the handlebars. After much research I purchased the quill extension form CJS cycles, this gives me a more upright position and greatly improves both comfort and vision.
The service from CJS was excellent with a very quick delivery and the product is a good value quality product.
Fitting requires a long reach Allen or better still a hex T bar.
Although I only have limited experience with CJS based on my order I would not hesitate to use the again and would recommend them for any cycling requirements.
Great Service

Consyou need a very long allen key to tighten the bolt
Prosraises the handlebar height
Following a hip replacement I needed to raise the bars on the bike I use on my Tacx Ironman smart trainer. This has done the job perfectly. You just need a very long allen key to tighten the bolt.

What is the maximum height of the extension?
25 Apr 2020
I would like to know the height from the max height mark to the top of the adapter.

Thank you!

Hi, it is 150 mm. Thanks 27/04/2020
My stem (22.2mm outer diameter) has a cone nut rather than wedge, will this still be suitable?
18 Apr 2019
Hi, yes it will work. Thanks 24/04/2019
Can this be used on a 16in wheel carrera cosmos?
05 Jan 2019
It is quite possible, but we do not know enough about that bike to say yes.

Thanks - 07/01/19
I can see I’ll need a long Allen key for this - can you tell me what size Allen key please? Thanks
16 Jun 2018
You will require a 6mm allen key.

Do you have this in a silver/chrome finish?
13 Jun 2018
We currently just have the black option I am afraid!

Thank you so much.
HI, sorry, I don't think they make one

If not do you have anything that will?

Providing your bike uses a standard 1 Inch threaded headset then this quill raiser is indeed a suitable product for what you're trying to achieve.

Outer Diameter Of Inner Section
23 Nov 2014
Hello, could you give me the diameter of the inner section?
Is it avaliable with a upper section diameter of 1" 1/8?

The inner diameter of the upper section is 22.2mm and designed to take standard quill stems used for 1" fork. This is just a stem raiser and is designed for use with 1" forks and you can re-use your current stems. Unfortunately this is the only item of this kind we have, the closest equivalent would be a stem converter to go from a quill type stem to a modern Ahead stem.

Could You Tell Me The Outside Diameter Of Upper Section
20 Jul 2014
hi , i would like to know if the oxford stem riser has an outre diameter of 25.4 on the upper section to allow it to be used as a high rise adapter for 1" threaded forks with a 1" ahead stem , effectively using it as a 1" quill to 1" ahead adapter ?
many thanks for any help

The upper outer diameter is indeed 25.4mm. We however would not recommend using it as a converter to an Ahead system as this is not what it is designed for. If you wish to convert to an Ahead system I would recommend you go to the 1 1/8" size, as there is a greater number of stems available. For this we'd recommend the Genetic stem raiser.
