I think the bike will be fine but you need to think more about your tires. Stuff the biggest thing in there that will fit, and fiddle with tire pressure so you don't pinch flat. On my Atlantis, 40 mm is a sweet spot between on-road efficiency & off-road security. I doubt you'll hurt the Sam at all.
Before I got my Atlantis, I rode mid 80s Panasonic DX-5000 (a pretty much UJB) that took 28s at best. I was just careful & slow (the slow part was easy) and never even had a flat off road. It did have the advantage of being easy to carry. dougP On Saturday, August 15, 2015 at 2:37:55 PM UTC-7, Lungimsam wrote: > > The kind with lots of sudden, deep, and uneven ruts, loose, big gravel > chunks, roots, and rocks that stick up 6 inches from the dirt that > your front tire will slam into when you can't see them coming because the > shade is so dark? > > Don't wanna trash my Synergies or bend my fork blades doing this.
