Numbnuts(3 posts)

Ok, I did a search of this board and didn't find the info I needed...
What is it with losing all contact with the "boys" on prolonged rides? I noticed it again on my mtb today, after grinding in the seated position for a number of miles up a steep, loose trail, my testicles might as well have been in another dimension for all the info they were reporting back to the cerebral cortex. The problem also occurs on my road bike.

I learned long ago to notice the early stages, get up off the seat and stand just for reasons of self-preservation and enhanced blood circulation (although that is not always an option on the mtb) I've messed with bike fit, particularly seat angle. I went to a Serfas Cosmos saddle with the "groove" down the middle...still, I worry for the state of my future sex life.
Is there a definitive answer/solution? This stuff is inspiring too many Freudian nightmares!

Most likely you have your seat too far back and are placing your weight in the middle of the seat as opposed to your sit bones on the back of the seat (where they belong). This is usually caused by tilting the seat downward to ward off the numb-nut thing which then moves your postion into the middle of the saddle. Make sure your saddle is dead level or even slightly up tilted and then get your butt bones on the tail of the saddle. If this doesn't solve the problem, then you have to go more into the seat route to find the best seat for you...

Good Luck

but don't let that divert your attentoin to the correct position on the bike. Move your butt around on the bike. Trial and error. I used to get numb from 2 hour rides but now I am comfy on Era, Flite, Prolink, SLR, etc. The only one that's really uncomfortable is the Fizi:k Pave.
