Optional Fuel Box holds real food or tech food for eating “on the run.”
The bag will hold one or two tubes with other tools.
Optional fuel box fits in any of our top tube bags.
The zipper opens in such in a convenient manner for GPS or light battery cables.
If you find the straps to be too long, fold & pinch them underneath as (medium bag shown).
The Medium is 1/2" wider than the Small. The Medium & Large and about the same width, but the top edge is shaped differently.

Follow the instructional captions in the following photos.
1) On most models (not on the small size) the stem strap can be adjusted vertically. For more stability, set it to the highest position your stem will allow. Be sure the doubled over portion of the strap is facing inward (see the next photo for clarification). 2) Cinch down the other straps—in particular, the rear strap should be VERY TIGHT. 3) The Cord Port enables you to run a USB cord from the inside of the bag to your GPS, while keeping the weather out.
The Spacer Pad can be added to any top tube bag stem strap. Gently slip it over the ends of the straps (you will need to rotate the nylon rectangular loop sideways) and snug it up so it is flush against the bag. On models with an adjustable height daisy chain, be sure the doubled over part of the strap (highlighted) is facing inwards.

eoGEAR Small Century Bag


This top tube bag will attach to nearly any bicycle: road, mountain, urban, tandem, recumbent, gravel grinder or cross. This model is just a tiny bit smaller than the popular Medium Century Bag (by about 12mm or 1/2") — also, it does not have the side pockets that the larger bags have.

  • Attaches to the top tube and stem of bicycle
  • One compartment which will hold most “standard sized” smart phones, even with a beefy case on them (iPhone 4 or 5 and most Android models)
  • Main compartment is sized to hold our exclusive fuel container (# 2451) — no more messy food in your jersey pockets
  • Zipper can be operated with one hand.
  • Exterior of the bag constructed of rugged 400-denier Nylon Pack cloth or 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 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.
  • Bag attaches with three hook & loop straps (no elastic that will allow bag to flop around)
  • Reflective strips on each side for use in dim light or night riding.
  • Light 4mm foam padding on bottom for protection of contents 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 while standing up to pedal.
  • We have had isolated reports of paint rubbing off caused from the straps or fabric on this bag. You may want to apply a piece of clear frame protection film or ISC so-called “helicopter” tape to your top tube.
  • This bag is version 1.0 and the eoGEAR top tube Spacer Pad will not fit on it. A later version, 2.0, will accept a Spacer Pad. 

Phone Compatibility

This bag fits the following: all flip phones, smaller iPhones, Samsung Galaxy S, 3, 4 or S5 all with a “normal-sized” case. A Samsung Galaxy Note 3 or 4 with a very small, minimalist case will fit.* The iPhone 6+ will fit, but it is very snug and not recommended. A “minimalist-sized” case usually means it adds only 1 to 2mm to each of dimension of a naked phone. Or, in other words, a phone & case up to approx. 153mm x 80mm (6.0 x 3.1") is the maximum size that will fit in this bag.

*These phones with a very minimal case fit inside this bag— only when tilted at a slight angle. One must exercise care when closing the zipper so it doesn’t catch the corner of the phone and scratch it. Otherwise, we recommend one of our larger Century Bags.

Richard’s Recommendation

On longer brevets or double-centuries, where one is frequently riding in the early morning or evening hours, it necessitates wearing a jacket covering your jersey pockets — this bag serves as a practical substitute for stowing and accessing the gear or food that is commonly kept there.
