eoGEAR Rolltop SeatBag™ 10.0
For years we have been struggling on how to make a high-volume seat bag that will fit on smaller bicycle frames—finally, this design accomplishes this!
This bag is similar to the Rolltop SeatBag™ 9.0 except:
- It is designed to provide more clearance above the rear tire, thus working with smaller bicycle frames.
- The opening of the “roll top" seals with Velcro.
- It has slightly more volume (10 liters vs. 9).
- It uses a seatpost attachment system that has no moving parts.
This bag is part of the eoGEAR SeatBag family — a system for the self-sufficient cyclist or randonneur. It features an easy-to-use roll-top “dry bag style” opening with one large compartment and three additional outside 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 as the necessary hardware is already attached.
- The bag is very compressible — on some rides you need to add or remove layers of clothing (i.e. swing season rides or night riding) and the bag squishes down, so the remaining contents don’t rattle around, similar to an internal-frame backpack. Near the bottom of the bag is a pair of Velcro-like straps that squish down the bottom of the bag, providing more clearance for smaller bicycle frames, down to approx. 50cm.
- Two pockets: one flat mesh pocket and a gusseted zippered pocket on the back side. The gusseted pocket uses heavy-duty #8 water-repellent zipper.
- There are extra D-rings for attaching additional gear or apparel.
- The rear of the bag accepts a Reflective Triangle (though because of the angle of this bag it may be be totally effective).
- The bag attaches in three places: first, around the seatpost with a German-made “SKS Anywhere Adapter” Velcro-style strap (it has no moving parts to fail), and then secondarily to the rails of the saddle with two nylon straps. The bag attaches to either Brooks or Rivet-brand leather saddles, or most tech/racing saddles, without additional parts. It is designed to work on either round or slightly oval posts. We have yet to test this on very narrow aero seatposts.
- The bag is reinforced with a stiff HDPE framesheet which give the bag shape and prevents it from sagging and then touching the rear tire.
- 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.
- 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.

An Equinox Horizontal Pack Pocket can be attached on the front side of the bag, under the saddle. It will yield almost a liter of storage space: ideal for crushable items like a pair of glasses, an extra tube or a very lightweight vest. (This may rub the back of some peoples thighs...experimentation is advised).
Rear Tire Clearance
You must have at least 18cm (7") from the top of your rear tire (or fender) to the bottom rails of your saddle, unless you opt to use the sewn-in compression straps (it reduces the volume of the bag by about 1–2 liters) in which case you can get by with 14.0cm (5-1/2") of clearance. See this page for more info on tire clearance of various saddle bags.
When attaching the bag to your bike, first attach the clamp/strap to the seatpost and wrap it around twice. Be sure that it has LOT of tension on it. About half the weight of the bag should be on the seatpost. This adapter is made from Delrin...it looks like plastic and has a rubber lining, so it can safely used with carbon-fiber posts. I have used it on three of my road bikes, all of which have carbon-fiber post for several years now...no problem.

Rants & Raves
“Thanks for a terrific product! Finally a bag system that holds as much stuff as a rack, but without the rack! I really like that the bag doesn’t rub against my thighs, even though I mount the bag on the front of the board.” (D.W. from Davis, Calif., Sept. 2011 regarding the RandoBag 6.8).
