I have been silent for a while so I will take a turn. The Rigida 13-19 were a very light rim. They were superseded by a simular but slightly wider Rigida 13-20, maybe the difference is a tire bead hook. The excellent Bicycle Guide magazine did a survey of real world rim weights in 1984 or 1985. The Rigidas were the lightest clincher rims at 415 grams. The Mavic MA-40 if my memory is right were 480 grams. The Rigidas had a narrower and deeper section than the Mavics. Rim sections increase as extrusion dies wear out during manufacturing causing thicker cross sections so there are variations in weight of maybe 5%(my guess). Advertised weight were usually lower than reality. The Mavics MA-40's were very tough rims. The Rigidas were my race rims light and fast but easily dented if you used too narrow or an underinflated tire. They seemed to use a low strength allow but they rode well and it was much easier to mount tires because of the deep center well. Doland, check to see if the dreaded MR TUFFY'S have stowed away in the tire carcass. These are the worst idea I have ever seen for tube protection a severe performance degrader.

Anybody know where I can find 27" tubluars? Also, does anybody know anything about Rigida 13-19 rims? I have a pair built up on some NR hi-flange hubs and they seem awfully sluggish. Tried a magnet and it didn't stick, so I think they are Al. doland cheung la, ca __--__--

Steve: Prugnat lugs, "Allez!" cinelli-esque crown...early 70's
It is known that Edwardes badged a load of Holdsworth Mistrals in the early seventies as Gillotts, they may have done others too. "Allez!" was a Holdsworth house brand, and they used prugnat lugs on the mistral, professional and others. I don't know what crown went on the mistral in 1971. The frame number cetrainly is not a holdsworth number...but if the wheelbase is 41" you may have a Holdsworth-mistral/Edwardes/Gillott numbered to the Edwardes system. Life's never simple, Norman
