Annoyingly , had to send this back.I purchased one a WK ago and loved it because its a great size , points up and out rather than down , space inside the medium is fab " for what I needed " - can add keys, medical cards , phone and energy sweets .Because I have two bikes , I thought, rather than keep changing them over I would get another for my other bike.This one came through and its poorly made , the strap piece that comes across to put the light in is not straight , and is a good 45 degrees out , which would mean the light would not site correct .This was a real shame , like it was stacked somewhere else !Other than that the first one I had (which is the same item )was fab .So always check your stitching !

Conozco bien esta marca siempre la he usado, este modelo en concreto es la primera vez, la he comprado por el tema de fijación a los raíles del sillín y poder dejar la tija libre ya que es telescópica, y aunque no lo fuese también la compraría ya que queda muy sujeta y te evitas las típicas marcas o roces que afean y desvaloran tanto la tija.Tiene un tamaño muy bueno para mí gusto 0'5 l según fabricante, en mi caso suficiente para quitar algo de peso de la mochila y tener más a mano lo más necesario.Es un puntazo también lo de la cremallera lateral lo encuentro original y cómodo también.En fin buena compra y estaba de oferta.Reconozco que no son baratas pero si las puedes encontrar en oferta vale la pena pagar un poco más por la calidad que tiene la marca.

Excelente calidad, lastima que es demasíado pequeña.

I have owned two Topeak wedge bags since 2013. Both previous bags were the "STW' version with the zippers on both sides. I mention those bags simply because I can comment on their durability and I would expect this bag to have a similar durability. Both bags were used for about three years before something broke. On both bags the stitching failed on the loop used to secure the seat post strap to the bag. I repaired the first one and used it for another year or so but simply elected to replace the second immediately with this bag. In all fairness, the second failure was likely do to my replacing the provided velcro strap with one made of a different material that was thinner, significantly stiffer and probably more abrasive. The loop failed shorty after I replaced the strap. I don't think there was a problem with the stitching and it would have probably lasted much longer if not for the replacement strap but I cannot be certain. Both bags were otherwise structurally sound, if a little rough looking. The fabric covering did fade and one of the front edges wore because I would brush it with my leg sometimes. Those bags, and this one, are large enough to extend beyond the edges of the saddle, so one might bump them, depending on how one rides. Never had any problems with the fixers or zippers. I have a road bike so I'm not getting the bag real muddy or anything that might foul the zipper. On this bag, the lining does stick out a bit in one spot and I have to push it in to be sure the zipper doesn't get caught. Have ridden in the rain, bags have been water resistant. Of course, I don't carry anything in the bag that it would matter so I don't really worry about it.I purchased the medium bag because it was the closest in size to the previous bags. This bag is large enough for pretty much anything most folks would need. In mine I have a spare tube, two CO2 cartridges, the inflater (small one), lever tools, allen wrench multi tool, some tube repair patches, caps for my Speedplay cleats, some spare valve stems, a couple of packs of wet wipes, and a small ziplock bag for bandaids, cash and the like. One might get a few more small items in there depending on how full one wanted to pack it. I don't think there is enough space to accommodate two tubes, but I have not tried.The bag does look a little lop-sided on the bike. Another reviewer mentioned this as well. You can see it in some of the reviewer pictures. It is due to the zipper being on only one side. I would prefer it to look a little more symmetrical, but I don't see it when I'm riding and it does not effect performance so its something I can live with. If that might be a deal breaker for someone, then they might want to look at the STW version. The zippers being on both sides make it look symmetrical. It also comes with some additional tools.Overall, I'm very happy with this bag. This bag's storage capacity is more than sufficient for my needs. I expect the durability to be good based on previous experiences with the wedge bags. Not sure if three years is great durability, but I think I may have been responsible for the failure of the last bag; it might have lasted longer. The stitching certainly seems solid so I'm giving Topeak the benefit of the doubt, plus it was starting to look a little rough anyway (faded and a little worn) though still perfectly functional.

Great bag. I really enjoy the rigidity of this versus the softer versions. It maintains it’s shape well. Has a nice reflective strip on it.

La bolsa me ha gustado y funcionado muy bien.Tiene el tamaño perfecto para llevar los accesorios que requiero.El que sea de carcasa dura, la hace perfecta y muy resistente.Cubre y protege lo que guarda aún bajo condiciones de lluvia.Se puede desmontar y montar muy fácilmente.Solo hay que considerar que esta se sujeta tanto del asiento como del tubo que soporta el asiento, lo que le da una gran seguridad y fijación, pero si requieres montar otro accesorio como una luz trasera, o una parrilla trasera, será complicado.

I was spoiled by the ICS Clip on the Fizik line of saddles, but recently got a different saddle not compatible with those clips. Velcro attached seat packs don't attach as securely, and if you're not careful with placement, the Velcro can catch on high dollar cycling clothing, causing premature wear. After some research, I found this solution and am very pleased with it. The clip installs on standard seat rails conveniently and the bag mounts to it quickly and easily. The size is just right for carrying essentials. A spare tube (700x23 w/80mm stem), CO2 Canister, injector and tire levers fit just right. There's also room for a mini tool, though I never carry one anymore. Without a mini tool, it's possible to carry a 29er tube. The bag is side opening, allowing easy access, and has a strap, and separate netted section for keeping things organized. Quality of workmanship looks great.
