Thanks, Hilary. Indeed, the next VBQ will feature a 1936 cyclotouring bike (with fenders and lights) that weighed 17.51 lbs., using 3/10 mm Reynolds HM tubing.

Issue 4 will have a comprehensive look at the technical trials. Some day (but maybe not in issue 4), I should be able to present either a complete trials bike or at least some parts in a photo story...

It's a fun topic, but in the end, the "customer" bikes from the likes of Singer and Herse weighed between 22 and 25 lbs. Still light for a bike with fenders, lights, rack, wide clincher tires, etc. But much more useful and durable than a stripped-out bike with superlight tubing. (Cheaper, too, than having to rework every component to save the odd gram here or there.)
