|THE BEST PART
The carbon frame is the best thing about this bike— each test editor at Bicycling who rode, felt, and reviewed this frame was impressed by it. And no, that’s not because we think carbon is always the superior material for bike manufacturing. It’s because the frame and fork on the Xenith Comp exceeded our expectations by feeling lighter than it weighs and riding with a smoothness that’s comparable to bikes costing more than $3,000.COMPONENTS
The Jamis Xenith Comp comes with relatively standard, reliable components for its price. Those components include Shimano Tiagra front and rear derailleurs, a 50/34-tooth Shimano Tiagra crankset, a 10-speed 11-32 cassette, Shimano flat-mount hydraulic disc brakes, 42cm 3T Ernova aluminum handlebar (size 56cm), a carbon Jamis seatpost, Selle Royal Seta S1 saddle, and 25mm Vittoria Zaffiro tires.
As stated above, you can buy similarly priced aluminum bikes with slightly better components, but you sacrifice the benefits of a carbon frame.
THE BIKE FAMILY
The Xenith Comp is the lowest tier of Jamis’s race- oriented Xenith line. Five other bikes exist within the family: Xenith LTD ($6,999), Xenith Team ($4,799), Xenith Pro ($3,199), Xenith Race ($2,599), and Xenith Comp Femme ($2,499). Each bike in the line features hydraulic disc brakes and thru-axles, and each bike, except for the Comp Femme, is available in sizes 48, 51, 54, 56, 58, and 61cm. The top-of-the-line LTD comes with a SRAM Red eTap groupset and 3T Discus C35 Team carbon wheelset. The Team features a mechanical Shimano Dura-Ace groupset and, at 16 pounds, is claimed to be the lightest bike in the line. The Pro offers a Shimano Ultegra groupset and the Race has a Shimano 105 groupset. Finally, the Xenith Comp Femme is a women-specific build that comes with a Shimano 105 groupset and is available in sizes 44, 48, 51, and 54cm.
