Hey all, this came up in another thread and I didn't want to go too off topic so I'm starting a new one. I'm looking into a new custom, low trail, 650b randonneur and from reading the reviews of bikes in Bicycle Quarterly, I've become interested in lightweight tubing and what the BQ folks call planing. I weigh between 160 and 170 depending on the season and am more of a spinner. My question is if folks seem to think that lightweight tube specs such as .7-.4-.7 tubes and Kasei fork blades would be too light of a spec for a rider like me on that type of a bike? The bike will typically carry a 10-15 lb loads with the occasional 30-40 more pounds on the fork on lowriders for the weekend camping trip, light touring, etc. Any insights y'all can offer would be greatly appreciated! Framebuilder's insights would be particularly appreciated
