Bumping an old thread - I've been trying to resolve my elbow pain whilst riding.
The symptoms are long lasting aching usually in the left elbow but often in both that slowly subsides over the space of an hour after riding.
After a bit of reading around I decided to try making a conscious decision not to lock out my arms while riding. This seems to lessen the subsequent pain.
I tried riding with a tight compression bandage on one elbow - initially during the ride it seems to make things slightly better but by the end there was no discernable difference.
My elbows seem worse in cold weather, so I tried a slightly baggy long sleeve top. This improved matters slightly.
I tried a tight thermal top and the loose top and this made quite a difference.
My current view is that the problem is caused by having the elbow joint repeatedly moved by external forces (eg when traversing bumps in the road) while there is load on the joint.
Reducing the load, or the number of bumps ridden seem like the obvious solutions.
Keeping the joint warm might ease the effects.
Hope that helps someone.
