Sizes in cm. Colors: Pearl White/Monterey Red. Also listed: front derailleur 105 FD-5700 braze-on; headset FSA Internal AheadSet, 1 1/8"; bottom bracket FSA Mega Exo, external bearing; chain KMC DX10SC; grips Jamis suede bar tape. Frame: Aero 7005 butted aluminum frame with aero down tube, flat-oval top tube, hydroformed airfoil seat tube with wheel cut-out, rear-entry horizontal dropouts. MSRP is the price printed on Jamis's US model page in a 2010-10 capture, inside the launch window. Geometry: Jamis's 2011 table swaps the STACK and REACH headers (a 493 mm "reach" over a 402 mm "stack" on size 51); stack and reach are stored the other way round, as Jamis's 2012 table for the same frame prints them (size 51: stack 497, reach 401).
