Can Increase The Handlebar Height Even More!

Works fine for what it's supposed to do but you can increase the handlebar height even more by discarding the handlebar part and fitting a length of aluminium tube in it. Can then fit a standard stem to it to raise the handlebar. Fit a standard steerer cap into the end of the tube to finish it off. You would have to pay about £80 for an equivalent.
Great Product

Great stem, does what it is supposed to. Living in the USA, I still use SJS Cycles on a regular basis. Great to deal with.

I have two regular back seat drivers, this allows easy adjusment for each.

Re. Steven Wilkes comment

What type of ‘standard stem’ would Steven have been referring to?
Would like to follow his idea.
You will simply need to match the stem clamp diameter to the extra tube you are fitting, and then select a suitable handlebar clamp and length.

What shim will i need to fit this stem to a 27.2 seat post
22 Nov 2017

You would need a shim with an outer diameter of 28.6. This can be found under sjs part #22922D286.

Stem Diameter (!)
22 Dec 2015
I'm afraid you have misunderstood my question. What is the diameter of the adjustable stem part of the unit, the one which you slide in and to of the seat post fixing.

Hi, apologies for that, the diameter measurement is 28mm for the sliding stem piece. Regards
