BlackburnGrid Seat Bag(Return to Product Page)

Blackberne products are always high-quality. This bag is well-made and had a great price point.

This is the largest bag of this type I could find.

It holds the required tools, phone and keys.

...love it, fits nicely with my Brooks Seat

Just enough room for my use. I can get a multi-tool , patch kit, tire levers, wallet, keys and a compact pump. Couldnt ask for more. If youre a gram counter this is not for you, but it just suites me.

I like the reflective side panels , they really show up .

Even the small size option is roomier than my prior bag. Add that to the easy access zipper panel and secure attachment strap and it stays on securely even on rough gravel and mountain descents. Reflecting side panels are a nice touch too.

Looks good, doesn't bounce around.

Enoug space for the very basics

Great Products

Everything I need is in the bag .

Its a good bag. Hold emergency repair kit and a multi tool. Only issue I have is color fading away within couple of month. My bike stays in garage, and only when I ride its in the sun

Blackburn does it again, great product, great size, nice reflective material, attractive and versatile. I have one on every bike I ride. Buy one, or two. You can't go wrong.

Easy to mount under your bike seat, but is smaller than I'd prefer. However, it does carry almost everything I need when out and about. (The rest goes into my pockets.)

Zipper hard to work

I should have gotten larger size

Fits everything I need to bring with me on my rides. Very well made.

I bought this seat bag for my spouses gravel bike. The quality and function is perfect for what she needs it for. At Plenty of storage covering all essentials for emergency repairs.

It holds my new larger cell phone, a energy bar and some bike tools

Small is Just enough for essentials. I fit 2-CO2 cartridges, inflator, multi tool, pressure gauge,tubeless tire plugger, 2 tire levers, mini jack knife, shock cord, and small plastic bag. I'm sure you could substitute a spare tube for the pressure gauge and one CO2, but I prefer to carry spare tubes in my jersey pocket.

Retention strap is simple, and keeps pack stable. Easy to attach and remove. Reflective side panels are a nice touch.

I purchased this seat bag to replace a Blackburn bag I've used for years. I shopped other brands but decided on buying a Blackburn bag again. I went with the large size, its a bit bigger than I need but still not too large. The water resistant material, practical inner design and great zipper all are nice features. This bag also secures tightly - no worries of it becoming loose. In use for a couple months, no complaints. Great looking bag as well.

I use a saddle bag for my MTB w/ dropper and while not a popular choice, I like to place my mobile phone plus a tube (a very light Tubolito 29). The Grid, Medium size fits both perfectly and does so in a svelte package.

The seatpost loop, according to Blackburn, is optional for this model. I use it with the dropper for added security, and hence lose a bit of usable drop for this bike, but that is worthy tradeoff for me
