I have been recovering from a bout of low back pain/sciatica for the past month. I am not entirely sure what brought it on, but I suspect cycling exacerbated the issue. At any rate, I am 6'2" and ride a 61 cm bike, with a 59 cm top tube. It is standard road bike geometry. I have now flipped the stem to raise the handlebars and that seems to help (riding a bit more upright).
I was wondering if any others have battled similar predicaments and whether they were able to tweak their fit on a road or cross bike to ease back pain (if so, what worked for you?), or if you decided to shift to a hybrid or mountain bike.
I am weighing buying a cross bike with a 57 or 58 cm top tube to try and get a more upright fit, or if I should just get a hyrbrid commuter.
Thanks for any assistance you can provide,
