Joel, Funny about Grant measuring your PBH. I've never been to Rivendell but have talked to Grant about bikes by phone. He asked my PBH and I told him I measured it at 83 and he said "you're probably an 85". I think he figures most folks don't get all the way up to bone when they measure. I like having at least an inch clearance even though I can ride a bike with less, I'm always thinking about a quick dismount off of the saddle. My latest bike, a GT steel commuter build has a 32.5 inch stand over measurement and I have clearance.of more than an inch. So, I think Grant is actually right about my PBH being closer to 85 than 83. I'd say buy the largest frame you can comfortable straddle so that you can adjust reach with handlebar and stem changes. A too small bike I think limits what you can do for your cockpit options. Doug Hansford
