Bontrager Race X Lite Wheels$1,000 1 of 7
The aluminum tubeless-compatible clincher rims (23mm) give tires a full shape for great traction. The included rim strips let you ditch tubes and go tubeless. The wheels have butted, bladed spokes, Alpina locking alloy nipples, DT Swiss hub internals, and weigh a reasonable 1,438 grams.
Easton EC70 SL3 Handlebar$210 2 of 7
The best thing about Easton's new carbon handlebar isn't the price ($55 less than the EC90) or the weight (233 grams for our 42cm sample). It's the compact profile. A short 75mm reach and 130mm drop are roomy enough for big hands but small enough to keep the brake levers close.
FSA K-Force Light BB386EVO Crank$580, compact crank; $50, bottom bracket 3 of 7
Cranks are a good place to save weight, but it can be tough to find one that fits your bottom bracket. This one is stiff and light (565g), and is compatible with most current BB standards. The rings shift quickly but less smoothly than other brands.
SRAM Quickview GPS Mount$20 4 of 7
Use this mount to position Garmin's Edge models in front of your handlebar for an easier view, or reverse it to hold the unit above your stem. Made of lightweight composite resin, it grips your computer more securely than Garmin's stock mount and costs less than some aftermarket options.
Specialized Oura Pro Saddle$200 5 of 7
Though targeted to women who race, this gently curved, low-profile saddle is extremely comfortable over long rides. A narrow nose and minimally contoured cutout reduce friction spots, while a stiff, carbon-reinforced shell and carbon rails create a light, efficient pedaling platform.
Rotor Q Chainrings$245--$320 (set of two) 6 of 7
Nonround chainrings theoretically smooth dead spots in your pedal stroke. These have a less extreme shape than the radically oval O.Symetric ones used by Tour champ Bradley Wiggins. Shifting is slow, but the range of gearing and customization options are unmatched.
