I have a 2005 Trek 1500 WSD road bike with original Shimano 105 STI brake/shifter levers. I'm looking for replacement hoods for the brifters because the originals are wearing out.
I believe the groupset model number is ST-5510. I also believe that ST-5500, ST-6500, and ST-6510 hoods should all be compatible (55xx = 105, 65xx = Ultegra, xx10 = Flight Deck).
Can anyone point me to a source to buy a pair of hoods for these levers? I've searched and searched and come up empty handed.
