Topeak Aero Wedge Pack Bicycle Bag with Strap Mount

A well made, nice size for your road bike. Will hold a replacement tube, CO2 cartridge, and “tire irons” no problem!

The wedge under your rear bicycle seat has a humble function--to transport the stuff you need to get back on the road in case you get a flat or another mechanical problem.You wouldn't think making one would be rocket science, but, in fact, these items do actually differ significantly one from the other. Most I've used are decently well made, but the difference is in the little extra things you might not have thought to ask about before you pick one up!PROS*Perfect size. Like Goldilocks: not too big ,not too small, just right! A small-size pack is not going to hold everything you need and a larger one is not going to fit neatly under the seat. When packed carefully, this holds: two extra tubes (when I ran over some briar thorns in California and instantly created Swiss cheese out of TWO tubes I realized, really, you need two!), patch kit, three tire irons, a multi-tool and $20 extra cash.*Attachment to the top portion of the seat uses velcro strips and buckles rather than a plastic "T." At first I liked the plastic T design, but I later realized this design can be very easy to install under some seats and a pain (possibly even impossible) under others. I would rather have one that won't create an issue if I switch it to another bike or get a new saddle.*Two nice elastic rings under the wedge for additional storage. I use it for the Lezyne Pressure Drive Hand Pump. Wow, amazing...you don't need a pump on your frame if you use this combination of products!*An attachment point on the rear for a light. Since I occasionally ride at night (sometimes unexpectedly if my ride goes longer than expected) this is a MUST HAVE. I simply put a red flasing LED light on the back of my wedge pack and if I need it, I switch it on. Really, there's no reason a wedge pack should ever be built without this attachment and thank you, Topeak, for understanding that.*Zipper appears strong and I expect it will take abuse. I abuse it by riding in rain, packing bag tightly etc. I will post if it ever breaks, if not, you can figure it is still going strong!CONS*Doesn't come in pretty colors. This replaces a really pretty blue one which matched my bike...but that saddlebag didn't have many of the features of this one, so out it goes.I also want to give a tip for those who were disappointed that wallet, cell phone and keys don't fit in this along with your emergency supplies. The purpose of this bag is not to hold that stuff. It's darn inconvenient since this type of bag is not designed to be easily opened to pull out one or two things and it's not designed for easy-off, easy-on if you go into a store. What you want is something in the handlebar bag family, for example, I have this one: Sunlite Handle Bar Bag, 2011 Model, Small, Black. You can put your wallet, keys, a snack and cell phone in here. If you have to lock your bike and go inside, you take it off in just a few seconds and carry it with you.

I've had this back strapped to my bike for three years now. I purchased the one with two straps because I wanted to avoid the plastic clip. This is a great pack and holds a lot. I like the cornucopia shape; the large opening makes it easy to use the pack. The velcro straps work well keeping the pack attached to the bike. I don't have any problems with it moving around or rubbing against my legs when I ride. The back of the pack has a strap sewn onto it so you can attach a light/reflector if you wish. In my pack I have a spare inner tube, a large multitool, an innertube patch kit and two tire levers. There is a mesh pocket on the rear flap that is great for holding small extras. I put a spare battery and a work gadget that is a bit smaller than a lighter. I also can fit my Razor phone in here too. I commute to/from work fairly regularly so I open/close it often. The zipper is very sturdy. I have yet to try it in expanded mode.This pack is well constructed and roomy. The large mesh pocket is very nice feature. I highly recommend this pack.Edit: I'm taking away one star because this is not waterproof. I rode home on slightly wet roads and noticed there was wetness inside when I took out my cell phone. I still like the pack though; it holds a lot.

I bought a similar bag here on Amazon. It busted a seam after little use. This one appears to be much better constricted. I found no problem with the seat post attachment that earlier reviews mentioned.

Purchased this under-seat pack after the zipper broke on my previous saddle bag.Installation is quick and easy. Though it does seem the seat-post strap Velcro isn’t stuck to itself much. Despite this, it’s remained attached without issue. It does have a tendency to slide down the post, causing the bag to tuck further under the seat, making it difficult to access the zipper. Putting a bit of rubber on the inside of the strap would likely solve this. The straps that attach the bad under the seat are a bit long, though a remedied that with the help of a little zip-tie to hold them coiled up.The pouch size is great. It holds my phone, wallet, and keys when I ride, along with a tire patch kit and multi-tool. I would note that the current iPhone 14 Pro Max is about as big of object it it’ll fit (without opening up the saddle bag extension). It’s just the right size to carry the things I need along for the ride, without weighing me down.It’s a great saddle bag that’s just the right size for everyday riding.

My use: I mountain bike in Colorado, and ride my street bike to work. This fits my sunglasses and clear eye protection in protective cases, keys wallet and phone, 3 Kind Bars / similar items, compact bike repair multitool and tube repair kit, but it appears very compact, air streamed. It's compatible with my rear wheel rack. I haven't used it in the rain or cold yet, but the design looks good for both. Three clips to install or remove from the seat frame make a nice win-win of secure attachment and ease of use. Probably one should empty it or unclip and take with them in urban areas since anyone could do those steps. Zippers seem excellent quality. Materials seem stout, not likely to rip or break. Expansion zipper is a nice feature I have not needed for the few things I stow. Perfect for rides that don't require stowing change of clothes or picnic or a second water bottle or items for work other than a flash drive.

Medium is the perfect size seat bag for most road bikers who don't want to keep their jersey pockets stuffed with gear. Downward angle of pouch makes loading easy. Strap along back allows using clip-on style rear light without the hassle of a dedicated light bracket. Has held up well over several thousand miles of riding.

Modèle M acheté pour pouvoir loger une mini pompe. Elle rentre parfaitement à l intérieur sans ouvrir le soufflet. La pompe mesure 18 cm il ne faudrait pas plus mais elle rentre sans forcer. Le petit passant sur l arrière est idéal pour fixer le support d origine du Varia sans élastique avec des colliers nylon. L angle de la pièce couplé à l angle de la sacoche est parfait pour la visibilité et la détection.

Finalmente un borsello sotto sella che si aggancia senza lo strappo, che dopo poco si allenta. L'unica pecca è l'occhiello aggancio al tubo sella , che non gira attorno bene . Per il resto, capienza media x una camera d'aria e attrezzata.

A snazzy little bag, it fits below my saddle easily using two straps and one velcro strap around the seat post. I managed to attached my ass saver underneath it too. The rest light attachment point is stable. There is room inside for a spare time, multi tool, tape, puncture repair kit with tyre leavers and space for some snacks and my keys. You can also extend the size with the zip on the side. It feels very solid and the zips feel sturdy.

Sサイズを持っていたのですがもう少し容量が大きいもが欲しくて購入しました。サイズ感は思っていたものがちょうど入って良かったです。容量調整ができるところが良いです。ジャバラ状になっておりジッパーを開けると容量がアップします。あまり荷物がない時はジッパーを閉めればコンパクトになります。ライトの取り付けも可能なのも良い点です。

This bag is very versatile and provides heaps of storage room. In its standard layout it easily houses a spare 29" tube, 3 tyre levers, a valve removal tool and a multi spanner toll and still has room to spare. But if you need to carry anything else it is expandable to allow more items to be carried. Added to this is the reflective safety strip across the lid and a mounting point for my tail-light. All of this adds up to make this a great seat bag.
