SILCA Mattone Grande | Bicycle Seat Bag secured by BOA Capture System | YKK Waterproof Zipper | 77 Cubic Centimeters of Storage Space | Bike Saddle Bag

Admittedly I am a fan of Silca products, typically very well designed and quality build. This is the best seat pack I've used, I have two, one for my gravel bike and one for my road bike. I prefer the "grande" as it's got about the perfect amount of space in it for my needs. Holds tools, spares, inflator, waterproof in all but perhaps the most extreme conditions. Attaches easily and securely, doesn't flop around when you are climbing out of the saddle. Unobtrusive, doesn't spoil the looks and the lines of a nice bike.

This bag is well made and holds 29” tube, small zip ties, tools and more. Tools do not clank around. Fastener is awesome as it cinches up nice n tight. No strap to go around seat post, so when post is dropped, bag does not interfere. Although a bit pricey, it’s worth it as you will not find anything to compare in quality and convenience.

It is the perfect saddle bag for long rides that fits securely under your saddle. I pack 2 tubes, multi tool, 3 CO2 canisters, inflator, chain links, money, and 3 tire levers.

It fits tightly under the seat. It is surprisingly roomy & holds a lot of stuff. Only drawback is that it is not very convenient to access stuff while it’s on the seat post.

I wasn’t sure which of the two sizes to purchase and initially went with the original Mattone…which was too small for my liking. I ordered the Grande and it’s perfect. There is nothing bulky about it IMO, and I can fit everything I need inside for pretty much any ride I would go on that didn’t need a change of clothes. I keep a multitool, two CO2 cartridges and a regulator, a tire lever, tubeless sealant, tire repair kit, and have room for keys, cash, and card. It fit’s perfectly behind my seat with room for my radar/light on the post. After reading some negative reviews about the zipper I decided to put on some zipper wax from my SCUBA kit. Seems to work fine for a waterproof zipper.

Stylish and works well

Made very well. Perfect size

After repacking it a few times I was able to get everything I need into the bag. Installing it through the seat rails was a bit of a pain, but once I got the hang of it, it was easy. The Boa tightens up really nicely and makes the bag fit snugly under the saddle.

Bel article en termes d'esthétisme, qualité et facile à installer. Système de fixation et pratique avec le Système Boa. Acheté la petite et la grande du coup ! Top 👍

Alles bestens - gerne wieder Tasche passt perfekt unterm Sattel und lässt sich lässig festziehen, geräumig ist sie ebenfalls

BOAダイヤルのお陰で装着しやすいかも。と思ってる場合は要注意です。我が家の場合は4台中1台にしか装着できませんでした。まずサドル後端にセーフティライトを付けてる場合は装着できません。ベルト長が足りないためです。例えば、スペシャライズド、トレック、フィジークなどのサドルにスマートにセーフティライトを取り付けてる場合がそれに該当します。また、サドルレールの後方に余裕がない場合、サドルレールとサドルバッグに隙間が大きく開く場合はベルトが届けば装着はできますが本体のベルトループに負担がかかるのでBOAを強く締め付けない程度に優しく取り付ける必要があります。目一杯締め付けるとベルトループが千切れます。つまり、サドルレールとサドルバッグを極力近づけて装着できない場合は、ベルトが届かない、もしくはベルトループに負担が掛かるなどの問題が起きてしまい装着が困難になる思ってください。またサドルバッグをフルオープンにするにはサドルから外す必要があり手間がかかります。ただ、サドルに装着したまま半開きもできますし、そのためのポケットもあります。スマートなサドルバッグではありますが、装着条件が厳しかったり、取り出しに手間が掛かったりして完成度としてはイマイチです。それでも様々な条件がクリアできた場合は他社のサドルバッグよりスマートな外観を手に入れる事ができるので、見た目を重視する場合は購入の候補に入れても良いと思います。価格も含め、万人におすすめ出来るとは思いませんが、自分は買ってよかったと思っています。

I'm a big Silca fan. I like the products and trust the brand and its philosophy. That's why I didn't think twice to buy this smart seat bag for my road bike.Unfortunately, on its first outing, we were caught in a thunderstorm, which we rode through. The bag sadly let in a lot of water and all my items were wet. I diligently dried everything but unfortunately, the zip is now catching and doesn't open or close without catching in several places.

Très pratique et surtout etanche
