Aero bars seat pressure

Postby rabbit stew » Thu Nov 21, 2013 9:33 pm

Iv just put some aero bars on my bike. Its the first time iv ever had any. When i grab the aero bars and rideim definatly getting some aerodynamics happening and and pushing a bigger cog from my position but im getting alot of upwards pressure from the front of the seat to my groin. Should i sit more forward on the seat, lower the front of the seat or now upgrade my seat to one that looks like it has a dropped nose on it.
Has anyone experienced this when they started using aero bars.
I,m not quiet. I just dont plan murders out aloud.

None of the above.

I realise this is a bit of a dig but since nobody had responded I figured I'd make a reply. Generally, a TT position on aero bars should have a similar hip angle to when you're riding on the drops. If you make no seat adjustments then bending forwards onto aero bars will close your hip/torso angle and give problems like you describe. To set it up to suit the aero bars, the seat needs to come forwards and sometime UP very slightly as well. Imagine you've taken a picture of yourself riding in the drops (side view), now you just want to rotate that picture until you're forwards enough that your elbows are on the arm rests.

This technique has all sorts of disadvantages too, namely ruining or at least changing your position when not on the aero bars and possibly affecting handling for climbing, sprinting, descending and cornering.
