S/Line Pro Frame Only vs Antenna Only: Which Part to Buy
By Alpine Outfitters | Published: 2026-11-02
Category: Comparisons
Replace only the worn stainless steel antenna or add a second S/Line Pro frame for another bike. Compare the two parts and pick the one that matches what's missing.
Quick answer
Buy the Antenna Only if your S/Line Pro frame is intact and the stainless steel antenna is bent, lost, or worn. Buy the S/Line Pro Frame Only if you already own the antenna and want to mount it on a second bike or replace a damaged frame.
The two parts are sold separately on purpose
The S/Line Pro system splits into a frame that stays on the bike and an antenna that does the visible work. Selling them separately means you don't have to replace a perfectly good frame just because the antenna took a hit, and you don't have to buy a second antenna just to set up another bike.
That split is also the main source of ordering mistakes. Check which half is actually missing or damaged before you add either item to your cart.
Where the trade-off shows up
The Antenna Only costs less and solves the most common failure: a bent or lost antenna. But it assumes your frame and its quick-release notch are still in good shape. If the frame is cracked or the quick-release screw no longer holds, a new antenna won't fix the mount.
The Frame Only costs more and assumes you already have a stainless steel antenna to move over. It's the better choice when you want to practice bikejor or kickbike with more than one bike, because the quick-release screw lets you move the antenna portion between frames instead of buying a complete setup each time.
Check compatibility before you order
The antenna has a notch designed for the S/Line Pro quick-release system, so it pairs with the S/Line Pro frame. The frame listing does not include the stainless steel antenna, and the antenna listing does not include the frame. Neither listing supplies a full set of frame fit dimensions beyond the 10 mm ionized aluminum frame, so if your bike has an unusual tube size or mounting point, confirm fit with Alpine Outfitters before ordering rather than guessing.
Trade-offs to weigh
- Antenna Only: lower cost, narrower fix: Choose it when the frame is undamaged and only the stainless steel antenna needs replacing. You save money, but you get no frame, no quick-release screw, and no second mounting point. Inspect the frame and quick-release screw before ordering; if either is compromised, this part alone won't restore the setup.
- Frame Only: more flexibility, higher cost: Choose it when you already have an antenna and want to move it between bikes or replace a damaged frame. You gain a second mounting option, but you must already own the antenna or buy it separately. Count your antennas before ordering: one frame per bike, one antenna to share.
- Buying both: only when nothing is reusable: If both the frame and antenna are missing or damaged, ordering both parts together is the only way to get a complete S/Line Pro setup, since neither listing includes the other component. Check the cart shows both items before checkout; a single part will not complete the system.
