I'm not sure if I should call the company TouraNick or NickaTech....what do you think?
Serioulsy, I haven't fully tested it yet, but I'm quite sure it makes a difference and they are very easy to make.
I got a piece of 3mm Polycorbonate from ebay and make some aluminium brackets.
The plastic pieces that hold the indicators have an inside and an outside, I separated these and drilled the holes for the brackest in the inside sections, so that if I take the brackets off then there wont be any visibility from the ouside that anything was done.
I then shaped the polycorbonate to fit into the gap making sure it didn't foul the forks.
Nick.
