They carry an assortment of bike brands, mostly high end like Ibis, Parlee, Banshee, Moots and Ventana. They do NOT carry folding bikes. So what do I do there? Well, similar to Lifecycle, sometimes I source my bike accessories from them. They sell Brooks and Carradice products. I think I bought Proofide from them before. They also carry Topeak stuff. I procured my Topeak saddle bag from BTC. I remember BTC used to sell Bern helmets. But the last time I checked they were gone.
BTC is known for its bike fitting system and organizing the Terry Larrazabal Bike Festival.
