Hi BibB,
I am interested in such a device.

I need to raise my handlebars also and I like the original BARS...so the best solution is to change handlebars raisers, instead of setting a piece of metal in between handlebar raisers and original bar.
I would ask you please to specify again the maximum height possible for the TEN without having problems with cables, since they are avaiable in 3 different: 50mm (2 inch), 75mm (3 inch) and 100mm (4 inch).
Please confirm also the model: Flat sided or round sided.
Thanks.
Jaume from Barcelona.
