Where to buy 2005 Shimano 105/Ultegra brifter hoods? 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.
My hoods were degrading too causing me to get black rubber on my hands after every ride.

I called Shimano and they said that they no longer support the ST-5500 lever and they do not carry any replacement parts.

I called Hudz, and they said that they do not have hoods that are compatible.

A STOPGAP SOLUTION: Rub your hoods with baby powder. It makes them much less sticky, and no more black residue.
