Answered Shimano I-spec question

[steve_sordy]

I have a XTM8000 shifter joined to a BR-M520 brake by an I-spec II clamp. The I-spec II clamp is supposed to offer a greater range of angle adjustment (between brake and shifter). But mine doesn't. In fact it appears to be almost fixed. This is on a newly supplied bike.

Before I start dismantling this, am I right to assume that there actually is a "greater range of adjustment", bearing in mind that this was Shimano's third iteration of an adjustable clamp.

On the "I-spec a" iteration, I had to separate the brake and shifter and use separate clamps in order to get the angle adjustment I was looking for.

You cannot adjust the shifter and brake lever angle independently on the I-Spec II clamp, it's fixed. You can just move the shifter sideways and the adjustment range is same as the I-Spec B.

Thank you Tamas for your very clear answer. It is what I needed to know. I will now find a separate clamp for the shifter and dispense with the I-spec ii. Do you forsee any problems with that, or do you have any advice?

No problem with that, I did the same.
Only thing is that you need this piece under the clamp when you remove the shifter to fill the gap.
