Yes, ovalize at the BB works. you shouldn't have an issue at the HT. I agree with Andrew, the ovalizing tool doesn't have to be high-zoot.

Using a 38mm downtube on a standard BB shell will be tricky. For anything that isn't lugged, I use a T47 shell. The larger shell decreases overlap between tubes and if you offset toward the bottom...

Repairing Bulged Steerer tube

Thought this might be interesting. I had to extract a stem from steerer on an early 80's Columbine. The prior owner buggered up the Campy SR headset obviously not knowing what they were doing. Well,...

I can't imagine a single bike that would require more than a 1220. If you've never built a bike before, don't waste your money on a longer beam to start with - many of us would argue that you...

You are including the triangle under the headtube and forward to the front axle. That wouldn't be within the fixture length. This probably frees up 200mm or so...I don't think anyone would ever...

I don't disagree with the idea of going as long as you can but generally with the long slack geometry, the rear end is quite short. I haven't done anything that didn't comfortably fit on 1220mm...

I don't think so. I think it's more that the timing (letting the puddle freeze and joint to cool slightly) and building up enough mass with the prior puddle that it doesn't re-melt when laying the...

I noticed that as well but wasn't sure if i was seeing what I thought I should see or if it was really opening. You can also hear 'pings' as the tubing heats and cools.

I have one of the small Grizzly mills similar to what Andrew has. The HT was 90mm Paragon so that helped. I used a tube block on the TT near the HT and put it in the vice with the BB up in the...

I have done a Paragon 44mm HT's this way. It wasn't as hard/time consuming to indicate it in as I was expecting. I would clamp the DT with blocks for more rigidity and take light cuts. A bigger...

Lowering the BB won't materially lower your CoG. That's way up at your hips so, bringing that down 10mm won't make any difference you could feel. The goal is gain standover and not have the bike any...

If the weight, fit and ride are what I wanted, I wouldn't worry about whether it's 853 or not. It wouldn't have a discernable effect on the ride - especially with our new fat tires. Also, speculating...

That's right, they have round ports. It's been a while since I looked at them but they struck me as a good idea given the trend to wider tires on all bikes.
