Is there a general rule for what is the maximum height (stack) of spacers advisable for a 1 and 1/8" carbon steerer tube? Specifically a Ritchey carbon pro. I checked their website and could not find info. Thanks.

"Given that most of the forks we sell have carbon fiber steerer tubes, we are restricted by industry standards to a limited 'stack height' of spacers. We can only stack a steerer tube as high as it is wide. In other words, for a 1" fork, we are permitted to stack the fork with 2.5cm of spacers. For a 1-1/8" fork, we can stack it 3.0cm."

flip the stem???

Although most steerers will work fine with 4cm of spacer, if you need that much, you'll get a more rigid setup with 2cm of spacer and the stem in the 96 degree position (instead of 84). If you need both, that's OK too, but I'd work on tolerating a lower bar or get a longer headt tube on the next frame.

FWIW, LOOK frames come with a 15mm extended top on the headset and 3cm of spacer.

I'll first work at tolerating the bar. My concern arose from back pain from this last weekend's ride. Fact is, I had a pretty significant chiropractic adjustment on Friday and then rode pretty hard on both Saturday and Sunday (after being off the bike for over a week). I have a bit of osteoarthritis in my middle back and was feeling pretty gimped after. More regular time on the bike before futzing with my fitter's good work is probably wise.:)
