## Description

Stay energized throughout your rides with the versatile SLS3 AERO Top Tube Fuel Bag offering easy access to all your cycling necessities while looking like part of the bike. Mount the AERO Pocket to your bike frame for aerodynamic, secure storage. Designed with a 15 angle to optimize aerodynamics, (Reduces drag caused by stem and headset spacers) the SLS3 AERO Bag puts gels, tools, electronics and other small items right at your fingertips. This bag attaches to your top tube behind the stem using two micro-adjust rail systems and straps. This system setup makes the Aero Box extremely stable and secure and prevents the bag from slipping off the frame. Other systems on the market only have one micro-adjust rail system which causes the bag to be moving around. The main zip compartment keeps everything within reach. It's constructed with resilient 600D fabric for protection in wet weather and fits an iPhone 6, a clif bar and a couple of gels. You can also store a C02 inflator and canister, tire levers, spare tube or a multi-tool.

Review: 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
Review: 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.

## Questions & Answers

**Q: Can you zip / unzip this aero bike bag for top tube with one hand?**
A: Yes. 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)

*by A***O on 5 June 2025*

La bolsa es de buena pero los velcros de fijación son de mala calidad, aunque cumplen su función si parece que se van a deshilachar. Le agregué dos pedazos de PVC en los laterales (como mencionan en otro comentario) y si queda más estética y espaciosa al hacerla semi-rigida. En sí la bolsa es pequeña pero es lo que buscaba.
