Re: [RBW] replace top tube to improve ride

I realized that there's another reason for the ride feeling like it does. Usually I ride this as a commuter, with a Kryptonite New York lock strapped on top of the rear rack, so much of my impression of the ride comes from this. Removing this saved about 7 lbs from right on top of the rear wheel.

I can vouch for the suppleness and fast-rolling quality of the 1.8" RH Naches Pass tire, in the "normal" as well as the "EL" versions. In my experience, they give up little, perhaps nothing, to the sublime rolling quality of the ultra light, 175-gram RH Elk Pass. But I doubt whether even the best

This reminds me of a, possibly apocryphal, story about a major motorcycle manufacturer that was testing a new motocross bike. The test rider complained that it didn't turn in well, and one of the engineers grabbed a cordless drill and drilled a hole in the frame behind the headtube. After a

As your framebuilder said, probably best left alone. But, as an amateur brazer, I'd solve the "problem" by cutting the tubes a bit less, leaving nubs to use as lugs for a tube with a outside diameter that matches the inside diameter of the existing toptube. This wouldn't get you down to 1',

Jan Heine sells 26"x 1.8" supple tires by Panaracer. perhaps a $72 investment would 'soften up' your ride to the maximum extent possible. If still too harsh, a new flexible frame would be the next step. I agree with the Tig welding affecting the head and seat tube integrity if welded a 2nd

I asked my local frame builder about this idea, and here's what he had to say: This is not something I would recommend doing. Since the frame is TIG welded my concern would be the integrity of both the head tube and seat tube after the top tube was removed and the weld remnants filed away. TIG
