Best Seat Wedge (Bag) Ever!
I've had a lot of these over the years. This is best, hands down! I love the one strap that attaches to the seat rails -- it's so easy to install, adjust and remove. They even put a small patch of hook/loop material, so that the strap on each side won't move before snapping the buckle. Very well thought out! It has plenty of space -- not too big or small, so works for my road and MTB. If I could offer one thing, many seat posts have a bolt , securing the seat, but the bolt head rests on the top of the seat bag. I'm noticing some friction wear starting. The wear is minimal, so far. I'm buying another one, so I don't have to keep moving it from bike-to-bike!
Secure, compact, stylish under seat bike storage
I had a heavy jangly load carrying: keys, cell phone, Swiss Army knife and glasses in my pockets. It’s high quality and very secure under seat storage. Has seat tube and under seat Velcro attachments. The zippered flap must be pulled up to open - eliminates accidental opening from vibration. It’s a little hard opening the zipper going around the corners and seat bottom interferes. outstanding color , went with rustic gold.
Perfect under saddle bag
This pack is a great bargain. Essentially the same as Topeak’s bag at a fraction of the cost. Actually, this one is better. Less bulky padding. Plus the Topeak one has a screw-on mount into which the bag snaps. But over time the screw can loosen and fall out unobserved. This one has simple Velcro strap mount. Easier and more secure. Holds a tube, patch kit, a couple of CO2 cartridges and inflator, multi tool and for me, a pair of cheap reading glasses.
Well made, great materials.
Exactly what I needed. Excellent attachment under the seat. Just enough for a multitool, tire irons, patch kit, and a spare tube. Could easily put a few more small items inside. Excellent quality product. Very happy with it.
Perfect Small Pack for Under Seat
This was the perfect small pack to fit under my seat without hitting my back wheel. It is just large enough to fit my keys (to car and Thule bike rack) and one or two other small items (e.g. license or map) to support my bike ride. It is not large enough to put a phone or bike gear in, for riding or maintenance, but it was just what I was looking for, for day rides of 10 to 25 miles, so I wouldn't have to cram keys or a snack into pant, shirt or jacket pockets. And the price was right, about $15 on sale.
Decent bag and great price.
Once I figured out how to attach it, I'm pleased. Wish it was just a little bigger but the price was right and it looks good on my 1995 Rockhopper gravel bike. Holds a tube, CO2 inflator, patch kit, levers, bike multi tool.
Small but usable pack
I bought this product to hold my lock and hopefully some other items. It holds the lock; not much else. It's a good item for the cost but not practical as the only pack for even a short trip.
Small junction seat bag
Perfect size to put things , nice color
Nice looking bag at a good price
Nice quality bag. Good looking and functional. Can clip a light on the back. Small, but works well on a road bike to stash a tube and a few things. Easy to attach to seat. Good purchase.
Good Value
Good value for the price. Needed a smaller bag to fit above a trunk bag and this literally fit. Carries just the basics, tube, tire irons, patch kit, multitool.
