Happy Holidays to All!
Brevet Bag 1.0 on the left & 2.0 on the right.
A vinyl wallet or smart phone will fit into the zippered pocket.
Small accessories fit in the mesh side pocket (Large Century Bag shown). It is secure with a hook & loop closure (with the loop on the exposed part so it does NOT snag your clothing)
Optional Fuel Box holds real food or tech food for eating “on the run.”
The Medium is 1/2" wider than the Small. The Medium & Large and about the same width, but the top edge is shaped differently.
Optional fuel box fits in any of our top tube bags.
Because of the height of this bag, we provide an additional stabilizing feature: a piece of rubber-type fabric on the rear top tube strap.
The bag will hold one or two tubes with other tools.
The zipper opens in such in a convenient manner for GPS or light battery cables.
Placing a small battery in the mesh side pocket enables powering of a GPS (or light) for longer rides. (Large size shown).

Please follow the instructional captions in the following photos.
1) On most models 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 precipitation 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 Top Tube Brevet Bag

Reintroduced, version 2.0 ~ Our largest top tube bag.

This bag is similar to the original Brevet Bag, but is more ergonomically tapered. It is designed, just as the first version, to hold a U.S. brevet card in the zippered outside pocket. This version does not have an internal divider however as the original did (according to a survey, most owners of the original version found it not to be a useful feature). 


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.

  • Available in only color scheme: black with a dark gray accent.
  • 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 exterior of the bag constructed of rugged 400-denier Nylon Pack cloth & 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 (most other manuf. 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.
  • It will hold one or two tubes, two CO2 cartridges, a small tool and a couple of tire levers.
  • 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
  • Closed-cell foam padding on bottom for protection of electronics against vibrations of road or trail.
  • Included is a Fold-over Poly Envelope (4916), which fits inside the outside zippered pocket. 
  • Because of the extraordinary height of this bag, it has an extra stabilizing feature: a piece of rubber-like fabric on the rear top tube strap.


  • 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 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.
  • Shorter cyclists (~ < 5' 8") may find when they dismount that they catch their thigh or crotch on this bag.

Optional Accessories

  • The main compartment is sized to hold our exclusive fuel container (# 2451) — no more messy food in your jersey pockets
  • The outside zippered pocket is specifically designed to hold the optional Liberty Mountain Waterproof Wallet (# 4915)
  • Top Tube Extension Straps for tandems or recumbents, which have a larger diameter top tube (# 2446)

Phone Compatibility

This bag will fit phones up to 183 x 95 mm (7.2 x 3.75" or slightly larger) in size. These specs are for the Large Century Bag, which is a tad smaller than this bag. 

  • Samsung Galaxy up to S5 and Note 4 with a “jumbo-sized” case
  • iPhone 6+, 7+ or 8+ with most large cases, like an Otterbox Defender box

For smaller smart phones (i.e. iPhone 5, 6 or 7 and the X) choose the Medium Century Bag instead (# 2006).

Concealed Carry

This bag will fit smaller handguns that measure from the barrel to the bottom of the handgrip (measuring diagonally) up to approx. 170mm (6.6") in length. A Glock 21 (45 auto), for example, is much too large for this bag.

Independent Product Review

See this review from Bicycle Times magazine.

Brevet Cards & The Brevet Bag

The current version of the X-Large Century Bag is almost as tall as the Brevet Bag, but the outside pocket is a tad short to hold a brevet card. This model, on the other hand, is specifically designed to hold a brevet card, inside an eoGEAR Fold-over Poly Envelope (which we sell, SKU # 4916).

Richard’s Recommendation

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


    Weight: 127 g (4.5 oz.)
    Volume: 1.3 L (79 cu in), with the sides of the bag slightly bulged out
    Inside Dimensions (bottom of the bag at the widest point): 12.7h x 21.5w x 4.4d cm (5h x 8.5w x1.75d"). Note, this bag is slightly wider at the front increasing the depth to about 5.0cm).
    Outside Dimensions: 13.2h x 22.0w x 5d cm (5.3h x .875w x 2d")

    This bag attaches to a top tube with a circumference up to 18cm (7"). If you using a tandem or recumbent with larger-than-typical tube size, then purchase our optional Top Tube Bag Extender Straps (# 2446).
