I adjusted my measurements after you quoted that after taking more measurements and getting more accurate numbers. I'm quite tall. I can't foresee reach being an issue. I'm generally at the tall end of the limits for the largest usual factory frame offerings and I've got a long wingspan. The current stem on the road bike is approx 12.5cm and on the hardtail 9cm. The hardtail bars are 71cm from end to end and the ends of the bars deflect back approx 5.5cm from the bar center.
