Just wanted to see if there are any fellow bicyclists/ motorcyclists with dup's. If so, how does it affect your riding? Pain? Progression? Know of any good gloves, or other tricks/ treatments that help? After discovering my condition, I am reluctant to get back on the bikes. I don't have any contracture yet, just a nodule in each hand, and possibly more growing, as well as possible ledderhose. I just hate to let it rule my life like so. All of my many hobbies involve using my hands/feet...

What you say is not quite true. The Reykjavik study showed clearly that, in Iceland at least, workers with heavy manual occupations (labourers, seamen, farmers, masons, carpenters, blacksmiths, etc.) were statistically more likely to be Dupuytren's sufferers than average, while men in professions requiring a university degree were statistically less likely than average to be Dupuytren's sufferers. (See the thread 'Dupuytren's and Insulin Resistance for details.) - Of course, it may not just be the manual work that damages their hands; it may be that seamen and farmers etc. work outdoors in the cold more often than average.

I was interested to read some correspondence about biking and dupuytren's. I've been mountain bikng for 15 years and have a lump in my right palm. I've often suspected it was exacerbated by blasting down hill holding on for dear life! I recently took a purler into rocks and have badly damaged my wrist ligaments on the same hand. This has made my dupuytren's even worse, pulling it in by at least a further 10 degrees. Surgery now seems my only option.
