Steep discounts on Amazon right now for small size Serfas Speed Bag seat bags in orange and green only (subject to change at vendor whim).

These are excellent seat bags. You'll be pleasantly surprised if you've only checked out the more commonly seen wedge bags from Topeak, JandD, etc., for general cyclists, or the Arundel, Lezyne and various ultra-compact bags more popular with roadies. The two discounted colors are a steal, especially if you're already an Amazon Prime subscriber.

I bought the orange for just under $7, and the price dropped a few cents more since then. The green was available for just $8.95 last time I checked, down from $12 earlier this week. The gray/black and red in small, and all medium size bags are the usual price, around $22 small/$24 medium, full MSRP. Serfas products aren't often discounted so they're usually priced the same whether it's Amazon or your LBS. The exceptions are for discontinued items or stuff that moves very slowly.

Presumably nobody wanted orange and green. I don't care. Some days even my socks don't match.

A bit about the bags...

I've had the medium size expandable Serfas Speed Bag for about a year, swapping it between my hybrid and road bike. At times it's been stuffed to the gills, even with the bag expanded on all day/night rides, to accommodate: my Topeak RaceRocket HP (a snug fit) when the rubber band retainer broke on the bottle cage mount; a largish USB battery to recharge all my stuff; two or more energy bars; spare tube, multi-tool, levers; Lezyne patch kit (barely takes any room -- those self sticking patches are excellent); tube of glucose tablets for emergency bonks, with a few ibuprofen, asthma pills, etc., stuffed inside a baggie inside the tube; couple of small Mylar single serve packets of DripDrop or other electrolyte powders; Missing Link for the chain. If I'm not wearing a jersey with pockets, I might also be able to stuff in a small wallet with just my ID, debit card and cash, my keys and, if I omit an energy bar, my little iPhone 4s.

Despite the abusive overstuffing, nothing has torn, worn, frayed or shredded. The zippers still work perfectly. These are really well made bags. And exceptionally well designed. I compared every wedge bag I could find and nothing else was quite as good.

Features:

• The bag has top and bottom stiffeners to retain the wedge shape.
• Tough dual zippers (and a single floor zipper on the medium expandable bag).
• Two slip pockets inside: one mesh pocket in the flap lid where I keep my Lezyne patch kit envelope and Missing Link; another along the right side, just enough for a baggie of first aid supplies, a Mylar envelope of electrolyte powders, etc.
• A snap for keys in the lid.
• Reflective stripes all around that really work.
• Good quality Velcro/hook-and-loop straps: one on each side for the saddle rails; one for the seat post.
• A fabric belt loop for a taillight. It'll hold my Cygolite Hotshot securely, but not the Planet Bike Rack Blinky, which lacks the retaining nub of the Hotshot.
• A couple of ballistic nylon loops on the outside lower corners. Not sure what they're for but conceivably a spare folding tire or something else could be secured there with bungee cord or zip ties. Or the loops could be zip tied to the seat rails to eliminate any bag wiggle.

The small bag will hold two Presta tubes if rolled tightly, and a small multi-tool. I usually carry a single Presta tube and a plastic tube with glucose tabs, asthma meds, etc., or an inhaler, since I need those more often than I have flats.

But the medium was larger than I needed for most of my 20-30 mile fitness rides on the road bike, so I'd planned for awhile to get the small. I was just hard to swallow the $22 MSRP for the small bag. But at less than ten bucks? Heck, yeah. Might even buy another in green just to clash with my red bike.
