Available in 38cm and 40cm center-to-center.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch4\u003e70 reach, 128 drop — what those numbers do\u003c\/h4\u003e\n\n\u003cp\u003eReach is how far forward the bar extends before it curves down. Drop is how far below the tops your hands sit in the hooks. Together they decide whether your position is one you can hold, or one you bail out of after twenty minutes.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e70mm is the shortest reach in Zipp's Service Course lineup.\u003c\/strong\u003e Traditional bars run 80mm or more, which pushes the levers far enough forward that riders with smaller hands are stretching to reach them from the drops — and a rider who can't comfortably reach the levers down there isn't really using the drops at all. Pulling reach in brings the controls back where they're usable.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e128mm drop is genuinely low\u003c\/strong\u003e without crossing into territory only a flexible rider can hold. You get a real aerodynamic position at the bottom, not the token drop shallow compact bars deliver.\u003c\/p\u003e\n\n\u003cp\u003eThe combination is deliberate: low enough to matter, close enough to hold. If you've been on a deep, long-reach bar and only ever using the hoods, this is the geometry that puts the drops back into rotation.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch4\u003eThe contoured top\u003c\/h4\u003e\n\n\u003cp\u003eMost of a long ride happens on the tops, and a round bar puts your hand on a small contact patch.\u003c\/p\u003e\n\n\u003cp\u003eThis one is flattened across the top section to spread pressure across more of your palm instead of concentrating it on a narrow strip. On a four-hour ride the difference is the kind you notice in your hands afterward rather than during.\u003c\/p\u003e\n\n\u003cp\u003eZipp specs the ramp angle at 10 degrees — that's the slope from the tops down into the bend, and it determines where your levers sit. A correct ramp means the hoods land where your hands naturally want them, with a smooth transition from tops to hoods rather than a step. 4 degrees of outsweep in the drops angles the ends slightly outward so your wrists stay straight in the hooks too.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch4\u003eChoosing 38 or 40\u003c\/h4\u003e\n\n\u003cp\u003eHandlebar width here is measured \u003cstrong\u003ecenter-to-center\u003c\/strong\u003e — from the middle of one drop to the middle of the other. Some brands measure outside-to-outside, which reads about 2cm wider for the same bar, so don't compare numbers across brands without checking the method.\u003c\/p\u003e\n\n\u003cp\u003eThe old rule was matching bar width to shoulder width. That still works as a starting point, but the sport has moved narrower — narrower bars are meaningfully more aerodynamic, and most riders adapt to a size down from what they'd have been sold ten years ago without losing control.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e38cm\u003c\/strong\u003e — riders with narrower shoulders, anyone prioritizing aerodynamics, criterium racers wanting to get through gaps.

If you drop a size, expect a ride or two of lever adjustment, and possibly a 10mm longer stem to get back to the same effective reach.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch4\u003eAero extension compatibility\u003c\/h4\u003e\n\n\u003cp\u003eThe \u003cstrong\u003e40cm is clip-on compatible.\u003c\/strong\u003e If you're building a bike that will run aero extensions for time trials, triathlon, or long solo efforts, order this width.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003e38cm is not rated for clip-on extensions.\u003c\/strong\u003e Don't mount them to it.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch4\u003eWhy alloy\u003c\/h4\u003e\n\n\u003cp\u003e6061 aluminum is the workhorse alloy of the bike industry, and on a handlebar that's a feature rather than a compromise.\u003c\/p\u003e\n\n\u003cp\u003eAlloy tolerates clamping mistakes. Overtighten a stem faceplate on a carbon bar and you can crush it invisibly — the damage doesn't show until it fails. Aluminum is far more forgiving of a mechanic in a hurry, survives crashes that would write off carbon, and gives you a clear visual warning if something's wrong.\u003c\/p\u003e\n\n\u003cp\u003eOn a part this size the weight difference against carbon is under 100 grams, and against Zipp's own 7050 SL version it's 35 grams. Whether that's worth double the price is a question worth asking honestly — the fit numbers are identical.\u003c\/p\u003e\n\n\u003cp\u003eBead blast black finish, understated on the bike.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamp diameter:\u003c\/strong\u003e 31.8mm — fits any standard modern road stem\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 38cm or 40cm, center-to-center\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClip-on extensions:\u003c\/strong\u003e 40cm yes, 38cm no\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable routing:\u003c\/strong\u003e External, under the tape\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eConfirm your stem is 31.8mm clamp before ordering.
