FlexDin Bicycle Triangle Frame Tool Bag Aerodynamic Design for Road Racing/Touring, Cycling Under Seat Road Bike Top Tube Pack Pouch Waterproof 0.6L Black

Awesome fit for mountain bikes without a lot of space in the middle of the frame. Most triangle bags took up too much space, and saddle bags aren’t a good option when using a dropper post. This fit exactly what I needed but not much more. Inside the bag I’ve fit:-29er tube-Pedros tire lever pair-CrankBros multitool + case-Topeak D2 digital pressure gauge-couple nitrile glovesIt’s a tight fit and I had to move the mini-pump to the frame so I had some extra space in the bag to zip it. The larger bag would be nice so I could also stash some additional items and nutrition, but I doubt it would fit in the frame. Quality materials and zipper, could see this lasting for years.For reference on the frame, it’s a 2018 Marin Nail Trail 6, Medium 29”.

It's been easy to use but the velcro belt is way too long and I have to cut it as it bothers me while riding.

If you’re looking for a small good slimline bag, this is it! Not a whole lot of space, but excellent quality and fits perfectly!

Great fit and quality

Just as described

fits good

This is a nice bag to hold all your small heavy items like multitools, etc. I'm glad I bought it. It fits nice and snug - doesn't slap around at all.
