Rivendell will be able to grow by moving their off-the-peg frame production to Taiwan. Taiwan makes awesome bikes but can be a very confusing place in which to do business unless you really know the scene and have the right connections. I hope they are able to move more production to Taiwan and lower their prices.
Is Rivendell even interested in growing? From reading their website, I'd say so. The move to Taiwan for the production of the Bleriot seems to say so as well. If just 5% of the yahoos riding around town on mountain bikes switched to the far more practical/faster/comfortable type of bicycles Rivendells sells; business would be very good for Rivendell indeed.
