There’s been a relative upgrade in two-wheeled modes of conveyance over the past several years as more people have been stepping out of their cars and onto their bikes. It might be environmental concerns, or it might be this blog. Either way, bike lanes are more crowded, and not just with rapid fixed gears cheating death. Demand has resulted in a flurry of successful, hand-made bike companies flourishing. Perhaps most prominent is the UK and Oregonian-based Rapha. To kick off 2011, Rapha has teamed with four manufacturers on their Bicycle Collection, to be rolled out over the next two years. Beloved, Ira Ryan and Tony Pereira, Independent Fabrication, and Cinelli were all commissioned to create four bikes reflecting the variety of cyclists Rapha looks to court. None are cheap (they all come in at around $5,000), but all make for lifetime-long rides.
