Know of any manufactures that sell chrome forks w/ 1-1/4" tubes?

No in BMX. Most forks are 1 1/8" and some (a few still exist) are 1". What do you have that is 1 1/4"? I know some mountain bikes have gone that route.

I finally found an Auburn frame with the removable triangle. I thought I saw a 1-1/4" one time, a while back. It must have been 1-1/8", it just looked larger at the time. I'm just now getting back into riding.
A friend of mine built a down hill run about 100yrds long w/ some pretty large gaps. I weigh about 165lbs and just looking to build a strong bike. The last time I rode, I weighed 140lbs.

A 1-1/8" fork is plenty strong; just make sure to get an S&M Pitchfork or a Odyssey Dirt or Race fork.

Thanks, beerman.

Do they sell Yuengling beer out there?

1 1/4in forks are for heavy duty downhill mountain bikes. The headtubes on those bikes are made really big too, you wouldn't even be able to fit one in a bmx frame.

Do they sell Yuengling beer out there?

Couldn't tell you. I pretty much drink only Old English, Hefeweizen, Heineken, and Jaegermeister.
