    Great Toolkit Bag

    Posted by Barrett on Apr 19th 2021

    I use this bag to hold a small tool/repair kit and my bike lock; a very convenient place for such things. It's big enough to hold all of that and a spare inner tube and a pair of tire levers, but not so big it rubs up against the tires, even with the seatpost all the way down.

    Perfect Seat Bag

    Posted by Ben Johnson on Aug 24th 2020

    This seat bag is awesome! I love the size of it. It's perfect for packing a lunch or for throwing in an extra layer for those days when you aren't sure what you are going to need. The light loop is in a great location for adding a rear light. I was able to get the leather straps tight on my seat post and saddle, where it doesn't move around much. When looking for a seat bag I couldn't find one that was similar in size to this one (usually they are too big or too small). But Frost River did it right again with this right sized bag!

    Nice vintage touch to my vintage bike

    Ordered this for my Eroica Bike and Ride and it matches the Brooks saddle exactly like the picture. I only wish I ordered the larger bag. It secures all the contents well.

    An Excellent Midsize Bike Bag

    Posted by acmastering on Jul 19th 2017

    Aside from the great vintage looks, this seat post bike bag carries just about everything you'll need for your ride. I have all my biketools in there, suntan lotion, wallet, phone, zefal bike pump and snacks! I've only had the bag for about 3 weeks but so far I'm very pleased with the design and attention to detail that went into the design and make of the bag. Great job Frost River!
