The other day I got the beginnings of cramp in my left tricep putting a gel wrapper in my back jersey pocket, and it really wanted a stretch. This happens every now and then, especially when it's only just warm enough for bare arms, as it was on Sunday
Try as I might I couldn't find anything good. This bike with its aero bars isn't good for riding hands free (you have to go pretty fast to avoid a big slow oscillation, but then there's a quick and growing oscillation in the steerer) but I didn't want to stop. Eventually it eased from riding one (right) handed for a few minutes, trying various positions for a straight left arm, but a stretch would have been far better.
Is there a tricep stretch that can be used while going along?
