Install the AERO pocket on the bike frame for aerodynamic safe storage. Designed at 15 degrees to optimize aerodynamics (reduces resistance caused by shaft distances and headset), the SLS3 AERO Bag puts gels, tools, electronics and other small objects at your fingertips. The bag attaches to the top tube behind the shaft using two rails systems and micro regulation straps. This system configuration makes the Aero Box extremely stable and safe and prevents the bag from slipping off the frame.

I used this during the IRONMAN 70.3 Eagleman, without any practice, I was able to easily open and close it during the race while holding 20+ mph the entire time. Plenty of room for all your nutrition as well. **Q: Will these top tube bags for bicycles fit all essential material for riding (CO2 cartilage, inflator, spare tube, etc)?** A: I've got a cartridge, a tube, a Portland Design Works Shiny Object inflator, tire levers and a multi tool in mine. That pretty much fills it up. **Q: If I only put gels in the bag, how many can I carry?** A: Each of these cycling bags for road bikes will fit at least 8 gels (it depends on the gel type and size, but assume 8) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Dimension parfaite *by A***E on 27 June 2023* Il faut couper les sangles mais dimensions parfaites et facile à ouvrir . Espace suffisant pour y mettre une douzaine de gels. Bon rapport qualité/prix ### ⭐⭐⭐⭐⭐ Perfect size, great quality, couldn’t be happier :-) *by N***R on 15 January 2018* ### ⭐⭐⭐⭐⭐ Buena accesibilidad y tamaño ideal para una bolsa de cuadro. *by C***N on 23 October 2018* Bolsa pequeña en tamaño pero muy accesible y suficiente para llevar algunas herramientas, barritas y una batería externa para el móvil. De hecho, yo la compré para esto último y me ha ido de maravilla. Ahora llevo el móvil conectado a la batería externa ya que al usarlo de GPS consume mucho y, de esta forma no tengo que preocuparme en toda la salida por larga que sea. Las correas de sujeción son largas pero una vez instalada, las ajustas y las cortas a la medida del cuadro y la bolsa queda perfecta. ## Frequently Bought Together - SLS3 Aero Top Tube Bike Bag - Small, Stable & Secure for TT and Triathlon Racing – Tri and Cycling Accessories - Premium Low Profile Design Reduces Drag - Custom Fit Bike Top Tube Bag - Profile Design Aerobar Bracket Riser Kit Black - Chamois Butt'r Original Anti-Chafe Cream, 8 oz tube --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/259648816-sls3-top-tube-bike-bag-aero-bike-bag-for-triathlon](https://www.desertcart.vu/products/259648816-sls3-top-tube-bike-bag-aero-bike-bag-for-triathlon) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-12*
