eoGEAR Ultra Top Tube Bag


This top tube bag will attach to nearly any bicycle: road, mountain, urban, tandem*, recumbent*, gravel grinder or cross.
*Tandems may require a pair of extender straps for the bottom Velcro-like straps as the top tubes of these bicycles are larger in diameter.

  • The main zipper can be operated with one hand while riding.
  • In addition to the main compartment, there are two pockets, one on each side of the bag: an exterior mesh pocket with quick-access Velcro closure for small accessories and a zippered fabric pocket for cash, I.D. etc.
  • The sides of the bag is constructed of rugged 420-denier Ripstop Nylon fabric (with a water-repellent coating on the inside of the fabric — we don’t use cheap polyester fabrics like some imported bags). The bottom uses a combination of smooth 400-denier Nylon Pack cloth and SlipNot, a rubber-like fabric. 
  • The main compartment has heavy-duty #8 water-repellent zipper (unlike most other manufactures which use a smaller, less durable #4 or #5). It opens from the front, so you can use it for stowing an external battery packs for powering your light or GPS.
  • The main compartment also has two large strips of Velcro loop on the inside and a corresponding moveable/removable divider for organizational purposes.
  • The bag attaches with three hook & loop straps (we don’t use elastic that will stretch out over time).
  • Reflective strips on each side for use in dim light or night riding.
  • 3mm closed-cell foam padding on bottom for protection of electronics against vibrations of road or trail.


  • Some cyclists do not like having a bag on the top tube as it may interfere with their knees, especially while standing up to pedal.
  • We have had isolated reports of paint rubbing off a bicycle which was caused from the straps on this bag. You may want to pre-tape your top tube first.
  • Shorter cyclists (~ < 5' 8") may find when they dismount that they catch their thigh or crotch on this bag.
