I bookmarked the "kneesavers" website - thanks Historian, I'll keep that in mind. As far as chondromalacia or other skeletomuscular conditions are concerned I'll see how my knees are over the holidays and if they still ache I'll go see my GP in the new year. Thanks for all the advice everyone, and BTW since my 10km ride with my seat post adjusted ala Mr. Danw's suggestions my knee pain seems to have pretty much disappeared. Let's hope it stays that way. Happy Holidays to all my fellow Clydes, Athenas, and even to you skinny cyclists. Ride safe and keep the tips coming - healthy knees make a great Christmas present!
