BlackburnGrid Seat Bag(Return to Product Page)

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 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

If you ride a Cannondale with the integrated "Smartsense" lights, size medium fits perfectly under the tail light.

Can carry 3 inner tubes & tools for long rides. The bag does move slightly while riding

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.

Got it within a few days. Just what I expected

Sleek and roomy. Simple to securely attach.

Well made

Bought this bag it fits very well on seat frame has plenty of room for tube co and tire changers and a couple of snacks

Well made; zipper seals out moisture, dust; would recommend this to anyone shopping for a seat bag

love size of bag

Perfect size for tire changing tools

Saddle bags seem to be a dime a dozen these days, with options coming from every corner of the world at an array of prices. This bag however, is the 5th I have purchased, and the best of any I have tried.

Highlights:

Straps are excellent, very strong, easy to take on and off, and effectively compresses the bag down if it is not filled to capacity.

The material is strong, and the "reflective" aspect of the black sides is present, though placed above my flashing taillight I'm not entirely sure how much it matters. Either way, its a cool bonus feature.

It is waterproof, as much as I can tell. I got caught in a torrential downpour, and everything in the bag was dry as a bone afterwards.

There aren't very many choices for a 1 1/2 liter pack and I like this one better than the only other one I was able to find (which was too long and skinny). The large size doesn't look or feel large on the bike but holds a lot. It holds a phone very nicely on the internal shelf (keeping it away from everything else in the bag). It's hard to find a bag that's the right size and shape to hold a phone but this one does. It doesn't have a key clip so I added my own. If you have a problem with the velcro rubbing on your shorts, it's probably because you have the grippy side out. All you need to do is reverse it so the fuzzy side is out.

This is my second Grid Seat Bag, the first becoming unusable after the zipper did not track anymore. That being said, I got 8 years of service out of my first bag, so expecting the same here. The bag is ideal for most of my rides (I use a bar bag on long rides, however). Solid construction. One thing I do is to pack the bag and then cinch it down.

I selected for a minimal size bag and fit a road tube, repair kit, air canister, tools and a bag with napkins, wipes, band aids and duck tape. There is still room for a wallet or cable lock. Bag is light and is water resistant with sealed zipper.

Works fine, very basic. Medium too small for cell phone in protective case. But holds patch kit, tire irons, basic tool kit, snack bar and keys and fits very well beneath the seat. Haven't ridden in rain yet, but looks like it will keep things dry for awhile.

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

Medium fits a tube, tire levers, couple CO2 cartridges and few hex wrenches with a little bit of room to spare. Not going to fit a smart phone in this. Would not want to go any smaller.

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