The optional 2.5 Add-on Pocket can be added to the back for additional capacity. It attaches in four points.
The inside of the bag has an aircraft grade aluminum plate (i.e. stiff, but light) which gives the bag unmatched stability.
Included is an elastic strap which you can slip over the saddle while packing, yielding a more upright position of the bag.

eoGEAR Rolltop SeatBag™ 9.0


This new saddlebag is part of the eoGEAR SeatBag family — a system for the self-sufficient cyclist or randonneur. It was introduced in July of 2017. This bag features an easy-to-use roll-top “dry bag style” opening with one large compartment and additional pockets. The available colors are black with gray accent side panels or black with red accent. Other colors by request for an additional fee. Unlike the eoGEAR RandoBags, this bag does not require a separate saddle bracket or adapter — the necessary hardware is already attached.

  • The bag is very compressible — once you have removed a lot of the contents, i.e. clothing (i.e. night riding), the bag squishes down, so the remaining contents don't rattle around, similar to an internal-frame backpack.
  • Three pockets: two side mesh pockets and a zippered pocket on the back. 
  • There are two pair of D-rings for attaching additional gear or apparel. One pair is on top near the saddle and another pair is on the rear zippered pocket.
  • The rear of the bag accepts the Add-on Pocket 2.5 and/or a Reflective Triangle.
  • The bag attaches with the German-made SKS Adapter around the seatpost (only works on round posts) and two Velcro straps that attach to the rails of your saddle. It attaches to either Brooks or Rivet-brand leather saddles or tech saddles without additional parts.
  • The lower body of the bag is reinforced with a stiff HDPE framesheet, supplemented by a small piece of 7071-T6 piece of aluminum. This design greatly minimizes the side-to-side sway that is often seen on other large saddle mounted bags, especially when one stands up to pedal.
  • It is constructed of a combination of 6.5 oz. 420-denier Nylon Diamond Ripstop and 420D pack cloth. Both have a water-repellent coating on the inside of the fabric — we don’t use cheap polyester fabrics like some imported bags.
  • The pocket uses heavy-duty #8 water-repellent zipper.
  • Gray-colored webbing used for the compression strap for easy of use in dim light.
  • Reflective tape on the sides and rear of the bag.
  • We received one report that with a smallish road frame (52cm) with the maximum saddle set-back, that one’s legs may brush against the bag of the bag.

Rear Tire Clearance 

You must have at least 17cm (6-3/4") from the top of your rear tire (or fender) to the bottom rails of your saddle. For more details description, visit this page. Frames smaller than 54cm may not work with this bag as the bottom of the bag may rub on the rear wheel. Choose instead, one of the RandoBags, i.e. the RandoBag 8.2 with a Highboy or Supersize bracket.

 Differences Between the RandoBag 8.2 and this, the 9.0 Bag 

  • The 9.0 has more pockets for better organization than the 8.2. The zippered pocket on the 9.0 is larger than the 8.2 pocket.
  • The 9.0 has two mesh pockets instead of one, with each side.
  • The 9.0 has a more trim bottom, providing more clearance above the tire than the 8.2.
  • And lastly, the biggest difference is that the attachment hardware is sewn in, so there is no need to have a separate bracket (but consequently the 9.0 will not attach to the Supersize L Bracket, for those with REALLY small frames, i.e. 50cm).
