Well, the BMX fork arrived today. It's really quite well made. And it look's great too. But I don't think I'll be using it!
First of all, it weights a ton (well, 3.5 lbs. ...). Second, and more importantly, although the O.D. of the steerer is clearly the standard 1 1/8 in., the steerer tube is very robust so its I.D. is not 1 in. (25.4 mm). It looks more like 7/8 in. (approx. 22 mm). That means that the Dahon handlepost won't fit.
Looks like I may need to break out the crowbar after all !!!
