Klein bikes are made by Trek but designed by Gary Klein. These bikes are very meticulously crafted from ZR9000 aluminum and take 3 times longer to make than a Trek. Also, all Klein bikes have painted on logos rather than decals. Klein's come with Shimano and Campy groupos.
Giant provides affordable entry level and kids bikes, all the way from aluminum to carbon fiber frames. The carbon fiber frames range from the $1200 OCR to the top of the line 900 gram frame of the TCR Advance Team Race Bike. Giant even makes a chopper, which we have in stock.
