During today's track day I noticed that using my second and third fingers (correct names?) works best for me, control- and powerwise, YMMV. On the other hand (
) fingers 3 and 4 does a better job at the lever.
I looked at what was going on and noticed that my second finger (index?) grab the lever too close to the pivot - on the lever part which is angled different than the bars/grips. So, the two working fingers are connecting at different angled parts of the lever and are pushed against each other - it made me feel in less than good control and I didn't achieve the power I wanted at the lever.
The solution I'm going to try out: move the whole brake assembly ~10mm inwards. That should allow fingers 2 and 3 to grab the lever at the lever part which is probably meant to be worked.
Maybe pictures will illustrate what I'm talking about.... If you're bored I totally understand, but some of you will hopefully totally understand the importance of the details. After all we love the details, don't we ...
