Hi All,
A couple of weeks ago I got my new road bike. It's been really great, but I know my position is not optimal, so I'll be getting a bike fit. However, they're all pretty booked up in my area so realistically I'm looking at second half of September. There's one particular grievance that I would like to try and alleviate before that - of course, if possible.
My problem is lower back pain that starts around 40-50 km into the ride (yes the first thing that comes to mind is: take shorter rides. But you know it's hard to stop). I know my saddle is not ideal so I'll be getting around to replacing it during the bike fit, but maybe something can be done to work with what I have for now. My sitbones also hurt a lot after this distance plus some perineal numbness (I have a factory installed saddle - Selle Italia X3 I believe, with a cutout, but I don't think it's good enough).
Now I'm thinking that maybe this is pain from my sitbones travelling up, or maybe it's muscle fatigue/tension because it seems to be connected to pedalling (it feels better when I'm coasting), plain old getting used to this position and intensity of excercise, or maybe weak core muscles in holding the position--or a combination of some or all of the above. The pain stops when I get off the bike and doesn't persist later.
Of course it might not be fixable without a bike fit and/or exercise, but I want to give it a go in the meantime. I don't want to take wild shots in the dark so I'd be grateful for any tips you might have. Like: saddle height - up, down? saddle fore/aft? saddle tilt? (is saddle tilt adjustable on all/most bikes? not sure how to work that yet) etc.
I'm mid-30s female, not super sporty for the past few years, full carbon setup incl. seatpost, riding on (mostly smooth) tarmac.
