Zipp Service Course 70 Ergo Road Handlebar
Race fit without the race price
current price, $65.00
Race geometry and an ergonomic top, at a price that doesn't need justifying.
The Service Course 70 Ergo was shaped with input from pro fitters and pro riders, and it carries the exact fit numbers as Zipp's premium bars — 70mm reach, 128mm drop — with a contoured top section for all-day comfort.
6061 aluminum, 295g, bead blast black. Available in 38cm and 40cm center-to-center.
70 reach, 128 drop — what those numbers do
Reach 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.
70mm is the shortest reach in Zipp's Service Course lineup. 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.
128mm drop is genuinely low 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.
The 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.
The contoured top
Most of a long ride happens on the tops, and a round bar puts your hand on a small contact patch.
This 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.
Zipp 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.
Choosing 38 or 40
Handlebar width here is measured center-to-center — 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.
The 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.
- 38cm — riders with narrower shoulders, anyone prioritizing aerodynamics, criterium racers wanting to get through gaps. Also the pick if you're on a 40 now and find yourself riding with your hands inboard of the hoods.
- 40cm — the general-purpose width for most road riders, and the safer choice if you're unsure or coming off a 42.
Going narrower changes your reach. A narrower bar brings the hoods slightly closer and rotates them inward. 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.
Aero extension compatibility
The 40cm is clip-on compatible. If you're building a bike that will run aero extensions for time trials, triathlon, or long solo efforts, order this width.
The 38cm is not rated for clip-on extensions. Don't mount them to it.
Why alloy
6061 aluminum is the workhorse alloy of the bike industry, and on a handlebar that's a feature rather than a compromise.
Alloy 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.
On 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.

Fitment
- Clamp diameter: 31.8mm — fits any standard modern road stem
- Width: 38cm or 40cm, center-to-center
- Clip-on extensions: 40cm yes, 38cm no
- Cable routing: External, under the tape
Confirm your stem is 31.8mm clamp before ordering. If you're on an older 26.0mm stem, you'll need a new stem as well.

Installation
Use a torque wrench on the stem faceplate and follow the values marked on your stem, tightening bolts evenly in a cross pattern so the gaps stay equal top and bottom. Uneven clamping is the most common cause of a bar that creaks.
Set your lever position before you tape. The flattened tops and 10-degree ramp are designed to put the hoods in a specific relationship to the bar — find the spot where the transition from tops to hoods is smooth under your palm, then check it from the drops before committing.
Full documentation and torque values are available in SRAM's service hub for this model.
Bar tape is not included.

FAQ
Rider-owned in Phoenix, AZ since 2009. 5-year frame warranty on steel, aluminum & titanium · most in-stock bikes ship in 1 business day · 4.8/5 from 16,000+ reviews.
How does my bike show up, and do I need a shop?
That depends on how you order it:
- With Pro-Build (select models: $79.99, or $129.99 on Carbon Road). Our mechanics in Phoenix face the frame, set up and bleed the hydraulic brakes, index the drivetrain, cut the steerer to our stock length and torque-check everything before it goes in the box. That's the shop work that usually runs $150–$300 locally. You bolt on the bars, seatpost, front wheel and pedals, set your hoods and wrap your tape: about 20–30 minutes with a hex set and a torque wrench. Pro-Build adds a 1–2 week build queue.
- Without Pro-Build. Your bike ships mostly assembled, but it needs a full assembly and tune by a professional mechanic before it's ride-ready. Carbon, titanium and AXS builds that skip Pro-Build arrive unassembled with an uncut steerer, so your shop can build them to your exact fit.
Either way, a professional build is safer, rides better, and unlocks our better warranty tier (see below).
What does the warranty cover?
Every State bike comes with our Standard Limited Warranty against manufacturing defects for the original owner. No registration required.
- Steel, aluminum & titanium frames and forks: 5 years
- Carbon frames and forks: 1 year (2 years with ProBuild Advantage)
- Non-consumable parts (cranks, wheels, hubs, bars, stem, seatpost, pedals): 1 year
Not covered: wear items (tires, tubes, chains, brake pads, grips, bar tape, saddles, spokes, paint), rust on RAW finishes, crash damage, and labor or shipping costs. Full warranty details
What is ProBuild Advantage, and how do I get it?
It's our "you did it right" warranty tier for bikes that were professionally assembled and registered within 30 days of delivery. You get everything in the Standard warranty, plus:
- 2 years on carbon frames and forks, instead of 1
- Priority claim review: ProBuild claims go to the front of the line
- Faster help with shifting or braking issues, without the "did you tighten that bolt?" back-and-forth
- Shipping perks on approved warranty replacement parts
- Discounted pricing on a replacement frame or bike for up to 5 years from delivery, if a crash wins
To activate it: add Pro-Build when you order, or have a local shop assemble your bike and keep the receipt. Then register your bike within 30 days of delivery with your serial number (engraved under the bottom bracket shell) and proof of assembly. If you ordered Pro-Build, our mechanics already did the build. You just register.
When will my bike ship?
Most in-stock bikes ship within 1 business day, and you'll get tracking as soon as yours is on its way. Adding Pro-Build puts your bike in our build queue for 1–2 weeks before it ships. Shipping is calculated at checkout from your location and the size of your order, and bikes go out by UPS or FedEx Ground.
Outside the U.S.? We ship worldwide, and duties and taxes are paid at checkout, so nothing is due on delivery. Shipping policy
What if it's not right? Returns & exchanges
You have 30 days from delivery to request a return or exchange. Bikes need to be unused, in like-new condition and in their original packaging.
- Refunds: a return label fee is deducted ($45 for complete bikes), and original shipping isn't refundable.
- Exchanges: issued as store credit. The return label fee applies here too.
- Package Protection Plan (add it at checkout): covers loss and damage in transit, removes return label fees and deductions, and extends the window for exchanges and store credit to 60 days. Refunds stay at 30 days.
Pro-Build and other service work can't be refunded once it's done. Final sale, clearance and limited-run items can't be returned, and neither can international orders.
Can I pay over time, or use HSA/FSA funds?
Yes. Financing with Bread Pay splits your bike into monthly payments, and you can pay it off early with no penalty (subject to credit approval). You may also be able to use pre-tax HSA/FSA dollars through Truemed. A short intake at checkout checks your eligibility, which depends on your plan. HSA/FSA guide
Which size do I need?
Geometry charts, size guides and full build specs for every model are on our Size Charts & Specs page. Between sizes, or running a tall stack or long stem? Get in touch before you order. Pro-Build cuts the steerer to our stock length, and that can't be undone.
Can I see one in person or get it built locally?
Use our dealer & shop locator to find a shop near you for a look in person, assembly or a tune-up.
