I think yes. The 62s with 25.4 top tubes sometimes wiggled. So we went to 28.6 and it stopped. G On Jan 27, 12:27 pm, jim g wrote: > On Jan 26, 10:06 pm, "gr...@rivbike.com" > wrote: > > > > > Also: Bstone top tubes/down tubes were 25.4mm/28.6mm. RIVS are > > generally 28.6/31.8, with the occas

SOMA sells silver, 26 mm clamp stems in 17 and 40 degree slopes, though relatively few sizes are in stock at the moment. The 17 degree VO stems aren't due for a month or two. Bill On Jan 27, 11:14 am, Brewster Fong wrote: > For threadless, what appears to be missing is an upsloping SILVER > s

RB-1 geometries, 191-1994. BIG scans for easy reading: http://yojimg.net/bike/equipment/bridgestone_geo.php The RB-1 has about a 70mm BB drop, while most Rivs have 77-80mm of drop. So, to convert sizes between the two, subtract about 1cm from the Riv to get the RB-1. I have a PBH of around 86

My RB-1 measures ST: 59cm C-T and TT: 59cm C-C. So I think the larger Bridgestone's had a bit lower frames than most other frames at that time. I usually ride a 56-57cm road frames and 120mm stems. But with a 100mm the RB-1 fit like a glove. The shorter stem also reduce the the wheel flop effect f

The RB1 is a traditional road racing bike. You could try the on-line bike fit program at www.competitivecyclist.com for a guess at a racing / sporting fit. It returns three different recommendations, which they call the Competitive, Eddy and French fits. Here are my dimensions as measured by my

Take a look at Bridgestone catalogs Sheldon Brown posted on the Harris Cyclery website. The Bridgestone RB series bikes have steeper seat tube angles than Rivendells. Not sure about bottom bracket drop since the catalogs show bottom bracket height. The 1989 catalog is the first with the RB's.
