This magnificent Rene Herse was found in Argentina!

One of the things that is great about my job is attending various bike shows and gatherings. The ones I enjoy the most are about vintage bikes, swap meets, and the like. Interbike is the annual trade show an Las Vegas. It’s cool, but doesn’t have the soul or hold the interest for me that smaller shows do. It’s just too overwhelming and highly commercial. But after all, that’s what it’s supposed to be about.

Last weekend, Peter Weigle had an open house at his shop in Connecticut. He called it “French Fender Day” and it was, by all accounts, an overwhelming success. About 40 people showed up. Most brought rendered bikes to show and ride. There were a few equally welcome non-fendered machines as well.

This weekend, I’ll be heading south to the Philly Bike Expo. I’m really looking forward to the weekend! Photos and a followup should be posted early next week.

Shimano UN54 Cartridge Bottom Brackets Relative Chainline

Here are some measurements I took from some of the square taper cartridge bottom brackets we carry. The drive side length is measured from the edge of the bottom bracket shell to the very end of the spindle. These measurements should be good enough relative to each other for chainline adjustment, but I wouldn’t use this chart to compare with bottom brackets from other manufacturers, which may have different taper lengths.

Bottom Bracket	Overall Length	Drive Side Length
Sugino/Tange 68-103	103mm	18mm
Shimano UN54 68-107	108mm	20mm
Shimano UN54 68-110	111.5mm	20mm
Shimano UN54 68-113	114mm	22.5mm
Shimano UN54 68-115	115.5mm	23.5mm
Shimano UN54 68-118	118.5mm	25mm
Shimano UN54 68-122	123mm	28mm
Shimano UN54 68-127	128mm	30mm
