I got a set of these for christmas, in order to keep a bit of the wind chill from my fingers during my winter commute.
Piece of piss to fit, no problems with fouling levers and look preety good IMO.
The main shield can be removed with the main bar in place for summer, and they do indicators to fit into the slots in the side. I've not seen these though.

Anyway, I thought I pop up a few pics as they seem to be fairly new and I couldn't find any decent ones on the web for me to check out before purchasing them.

Please excuse the filthy bike...I'll wash it tomorrow!!!!

Excellent. Thanks for sharing. I've been looking at those too.

Do they really help keep your hands warm?

Do they flap around at high speed?

Do they replace your bar ends weights?

Thanks for any thoughts!
