Thanks for the suggestion.
I actually tried that before a long while back and I didn’t find it made a lot of difference but it might be worth another try. If that doesn’t help I might consider one of the following (if at all possible I’ll get test saddles first):
Cobb JOF
Dash Stage/Strike (the cheaper versions!)
Specialized Power (I’m not sure about this for the Tri bike although I suspect it would work for me on the road bike)
Specialized Sitero
Any other suggestions?
I might be able to get test saddles locally from a Specialized dealer. Unlikely to be possible for Dash and Cobb I think.
I tried my Specialized Power on my tri bike and wasn’t a big fan. I love it on my road bike. I ride a fairly aggressive road position and it allows plenty of pelvic tilt but when rotate you’re resting right on your taint and it can get painful after a while if you’re really far forward like on a TT bike. I rode a COBB Max on my TT bike as well and was never a fan. I tried a friends ISM Adamo Road and loved it. Road it for a few weeks on the trainer and just picked up my own.
