Updates to Soma's 29er and 650b MTB frames are in the pipeline.
We just have to be patient as they are not mass produced frames and the first batch is being hand made in Taiwan at the moment (using top quality Japanese Tange Prestige heat-treated CrMo steel tubing). Hey, frames like these are well worth the waiting for.
The first production batch is due to arrive in San Fransisco in early June. Models will be added to the website next month.
Here's what Soma Fabrications has to say about the new frames:
We came up with the B-Side name mainly to help Kirk Pacenti create buzz for 650B as a new mountain bike tire standard. We weren't alone on using puns: Carver Bikes had the Killer B and Haro had the Beasely. But that was over 10 years ago and we feel the name doesn't suit the times anymore. Our main reasons for thinking this?
1) MTB tire makers in their wisdom have chosen to put "27.5" on their sidewalls-- instead of using the original name 650B.
2) On a 45 record, side A had the song you bought the record for. The B-Side usually had a weaker track no one cared about. But now the 27.5" tire size is a huge hit on its own. So it hardly fits the role of the other tire size no one cares about.
We are making some significant changes to the frame this year, so it is as good a time as any to work in a new name.
So we give you the Riff (another music-themed name, a practice we started back in 2001 with the Groove).
