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 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 Large Century Bag / Crazy Quilt (assorted colors)

Note — this size of bag is also available in “regular” colors as listed here.


This top tube bag will attach to nearly any bicycle: road, mountain, urban, gravel, cross, tandem*or recumbent*.

*Tandems of “bents” may require a pair of extender straps for the bottom Velcro-like straps as the top tubes of these bicycles are larger in diameter.

  • For this wacky color scheme, we take scraps of fabric, that otherwise might get tossed, and hand cut them for use in this bag (aka upcycling). The color mixtures are totally random as determined by our stitching crew (which happens to be prisoners at a sewing shop in the nearby Utah State Prison). This hand cutting does requiring more labor, hence the increased cost. For roadie use, we like the  bright colors and increased visibility which most of these bags will provide!
  • 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 (unlike most other manufacturers 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.
  • This bag 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).
  • Available in various colors
  • 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 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.

    Optional Accessories

    • A Spacer Pad provides some space between the bag and bolts of your stem. Some people find the steering is smoother with this, but it is strictly optional (# 2459).  If your stem sits really high on the fork, with a bunch of spacers, then a Spacer Pad is not really needed.
    • 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 Vinyl Wallet (# 4915)
    • Tandems or “bents” may require a pair of our #2446 Extension Straps for the bottom Velcro-like straps as the top tubes of these bicycles are larger in diameter. 

    Phone Compatibility

    These bags fit the following: standard sized iPhone X, 11, 12, 13, 14, 15 etc. and many Samsung Galaxy S-series phones all with a “normal-sized” case or many larger “max sized” iPhones w/o a  case.*

    Large Century Bag, version 3.0:
    The maximum size smartphone, including the case, that will comfortably fit in this bag is 160mm x 80mm (6-3/8 x 3-1/8"). 

      Large Century Bag, version 4.0:

      The maximum size smartphone, including the case, that will comfortably fit in this bag is 165mm x 85mm (6-½ x 3-3/8"). A phone up to 183 x 93mm (7-¼ x 3-⅝") will fit, but only if it is stowed at an angle and the phone requires a little work to insert or extract. 
      Otherwise, we recommend the X-Large Century Bag instead (SKU # 2008).

      *A slim or “minimalist-sized” case is one that adds 8 to 10mm (up 3/8") to the total outside dimensions of a naked phone. 

      Independent Product Review

      See this review from Bicycle Times magazine.

      Richard’s Recommendation

      On longer brevets or double-centuries, where one is frequently riding in the early morning or evening hours which 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.


      Weight: approx. 88 g (3.5 oz.), some will weigh more due to the heavier “upcycled” fabrics that are used.
      Volume: 870 ml (50 cu in)
      Inside Dimensions (bottom of the bag at the widest point): 
      10.5h x 20.5w x 4.4d cm (3.9h x 7.3w x 1.75d")
      Outside Dimensions: 11.5h x 21.5w x 4.7d cm (4.5h x 8.50w x 1.85d")

      This bag attaches to a top tube with a circumference up to 18cm (7"). If you are using a tandem or recumbent with larger-than-typical tube size, then purchase our optional Top Tube Bag Extender Straps (# 2446). An extender strap can also be used on the stem strap of any our top tube bags, but typically that strap is more than long enough for the common 1-⅛" (28.6mm) threadless stems.
