What a useful, thank-god-somebody's-making-it bag. Designed especially & specifically for bikes where the tire’s big and the saddle’s low and a full-sized saddlebag won’t fit. The Slimsucker slips into that gap, and despite its size designation, holds a Medium amount of stuff.

BUT it's not just for small bikes. Seriously, it's wonderful for mediums and bigs, too. When you just want more room than a BananaSack, but you don't need the room of a BagBoy, HappiSack, or Bagabond.

Dimensions - 11" x 12" x 6"

Other ways to determine whether it'll fit your bike:

(1) On a Brooks saddle, uneeda saddle loop-to-tire gap of at least 9 inches

(2) FYI, if you have a saddle height of 70cm (your PBH is 81cm +) and a 700c x 48mm tire or less, or fenders, this will fit fine. For skinnier 700c, 650b and 26' the saddle height can be even lower. 

(3) You can rest it on a rack or fenders,, always. It may compress some, but it's not a big deal and is still the most voluminous saddlesack we make or have seen that'll work on smaller bikes.

The Slim Sucker is wide enough for a 13-inch laptop, and ideal for long dayrides and two-day’s worth of groceries. It has no outer pockets, but it fits a Kangaroo pocket perfectly, for wallet-keys-phone-repair kit. With only one strap, it’s quick to get in and out of it (it pulls on a wooden dowel to evenly close the bag). Like it’s bigger kin, it has a corroplast bottom so a load won’t poke your tire, a tongue-flap to secure and totally waterproof the contents, and all the fabric, leather, brass, and stitching details are just as good.  Make your road bike more useful with one of these.

OUTER FABRIC: All Sackville bags are made from cotton we import directly from Scotland. It is more tightly woven than any waxed cotton made in America. The gaps between threads are so small it hardly needs any wax, and with less wax, it stays much cleaner. Normal-common-American waxed cotton is more coarsely woven, so needs a heavier coating of wax. The extra wax on the coarse fabric isn't as waterproof, and picks up and holds dirt, so after a couple of years, it looks like an old railroad tie coated with creosote.

Note: The fabric is tough, highly abrasion-resistant, but if you pack it with sharp things and rattle around on trails like that, a hole will magically appear. This isn't a defect, not an oversight, not a "bad run of fabric." It's abrasion. Pack it well but don't obsess. If you get a hole, fix it yourself with leather or fabric glued or stitched on. It's a damn tough bag, but it's not steel.

LEATHER: Tough, American top-grain leather tanned and sufficiently oiled to weather well with minimal upkeep. Every couple of years smear some leather goop on it. The best is Obenauf's (we sell it, so do others), but any will do.

OVERALL DESIGN: They sit flat, and there are two benefits. (1) The load doesn't tilt or tend to spill out. Even if you don't use the security of the inner tongue-flap or buckle down the outer flap, the raised lower lip of the lower jaw + a flat bottom holds your stuff in there; (2) You get more usable room directly above the tire. This is best explained with a diagram, which we don't have right now.

DETAILS: Simple, usable, with sufficient convenience for anybody. Two D-Rings allow for attachment of our removable Kangaroo Pouch pocket — good for wallet, keys, phone, and whatever else you might want to take with you into the store while your bike is outside.

Especially notice the bottom outer, sometimes in a contrasting color. The extra layer of fabric repels water and abraision from an uncovered tire. A fender or rack makes it unnecessary, but it's there just in case. The two webbing loops make it easy to snug the sack to a rack as a way to foil a thief with plans for a quick get-away; and reduce bag-sway (which is a theoretical issue more than a real problem, but saddlebag newbies tend to fear it, and so...we say don't).

Two loops at the bottom allow you to cinch a big bag off of a tall uncovered tire. Like, let's say you let a friend use the bag and they don't have a rack or fender but need to carry a big load, and their saddle is low. Run a stick or  pencil or rod or cord thru these loops, and use an adjustable cord or strap to hike the bag off the tire. Tie it off to the saddle or straps holding the saddle to the bag loops. Creativity solves all problems!

FANATICAL STITCHERY: Every stitch terminates on the inside of the bag. The ends of the nylon thread are melted with an alcohol flame, then smeared while molten. They won't show, catch, or unravel.

Capacity: There are too many ways to measure in cubic inches or liters. There are ways to cheat. Expanded and bulged? Flat sides and mathematically? It's too confusing. Unexpanded, this bag holds a lot. Expanded—with extended flap and maxed-out tongue, it's a monster.

Washing instructions: Let the rain wash it. If it doesn't rain, blast it with a hose for 10 seconds once a year.

behind the scenes: We list it as one word and as two, slimsucker, slim sucker, to aid searches. There might be a way around that, but this is how we're doing it for now.
