I tried Bontrager Double Gel on one of my bikes. It was so good that I put it on my other roadie that was double wrapped.
I think that has been revised Peter to include shoes as well. As shoes are now considered equipment not clothing.
The 'Pro' bar tape used by Green Edge at the tour village felt really good...grippy yet shock absorbent. ( I was copping a feel of the scott foil opposite the green edge mechanics bay)
I use cinelli gel cork...in BLACK...though i do have one white saddle, sorry.
Prologo....it is cork...comes in different colours....and cheap enough to change it regularly....it looks the same as the tape made by ZIPP...but at one third the price.....cheap enough to be not disturbed about ripping it off if you dont like it.....gel tape heats up in the sun :(
