Where in the legs is the cramp? If it's in your calves (at the back, below the knee) then dehydration may well be the cause, so make sure you keep hydrated - even during colder weather. (and I think the mods might want to move the thread to a more appropriate subforum)
¿Que?A high saddle is more likely to cause cramp than dehydration.
¿Que?
Hmm .. I notice far more riders with their saddles too low. I saw a man the other day riding along with his knees sticking way out as he pedalled.Basing this from a lot of readings and research into Steve Hoggs and other high end bike fitters. Most people tend to have their saddles too high, causing pointed toes and rocking hips. Pointing your toes down is often a sign of a high saddle. The strain this puts the calves under is considerable, and a proper saddle height can eliminate the issue of cramping calves.

Having said that, I might try lowering my saddle a few mm - I realised the other day that I am pedalling slightly toes down.
I don't know what it is with Steve Hoggs' website but my Opera Browser doesn't like it! It gets stuck in an endless loop of loading and reloading without actually displaying the page. I'll try Firefox ...It is worth giving Steve Hoggs a google, he has some great philosophies on bike fit, John Cobb is another famous fitter.
It was difficult comparing positions on my 2 road bikes because they have different saddles and I use different pedal systems on them, but it did feel that the saddle was slightly high on my Cannondale compared to my Basso. I lowered the former's saddle by about 5 mm and have ridden about 45 miles since then. It is amazing how much difference that small change made! I don't get that feeling of stretching down with my toes now.I might try lowering my saddle a few mm - I realised the other day that I am pedalling slightly toes down.
