ProsEverything to gain
An absolutely brilliant product that saved me from having to buy a new pair of forks when a combination of old age and increased girth necessitated raising my handlebars. Easy to fit, light weight and doesn't look out of place

Purpose Of Small Hole?
By

Any idea what the purpose of the small hole shown in the second photo is for?
SJS Customer Service:
Hi,

This is occasionally present on items like this, the hole is mainly for dynamo cable routing.

Thanks.
What Is The Minimum Required Exposed Steerer?
By
29 Aug 2015
2 bolt designs often require 35 to 40 mm exposed steerer. but the single pinch bolt is lower on the column. would 27mm be enough
for a steel steering tube?
SJS Customer Service:
Hi,

This heads-up stem extender requires 34mm of exposed headtube for fitting.

Thanks.
Hi, Can This Be Used On A Carbon Steerer? Thanks.
By

SJS Customer Service:
Hi,

There is no specific warnings supplied with this stem raiser about fitting this to a carbon fibre steerer, it is however not something we would recommend due to the extra leverage and height which could put extra stress on the top of a carbon fibre steerer. If you are still interested in purchasing one, I would recommend checking with the manufacturer of the forks as they would be able to provide the most information about whether or not fitting one of these stem raisers would be safe.

Thanks.
Torque

whats the to torque spec on the bolt?
SJS Customer Service:
Hi,

There is no recommended torque value listed for this stem raiser, but based on the construction of the part and information on similar items on their website we'd recommend around 9-10nm.

Thanks.
Clamp Sizes?
By
14 Apr 2014
What are the clamp sizes?

1" or 11/8" for steerer tube?

25.4mm, 26.0mm or 31.8mm for handlebar?
SJS Customer Service:
Hi,

This stem raiser clamps to 1 1/8" steerer tubes and provides a 1 1/8" clamping area for you to clamp your stem too like normal.

Thanks.
