Review on SILCA MATTONE Bicycle Seat Bag with BOA Closure System - Full Waterproof YKK Zipper for Convenient On-Bike Access by Adrian Allen

I've been looking for a saddlebag that fits a 29" mountain bike tube and this one fits. However, I would like to point out that that's all you'll put in there, if that's your camera size, I tried putting 2 tire levers in there and eventually closed it, but only after it was forced, probably not a long-term use . Durability. But you can also put a credit card, cash or a key in there. The way it attaches to your saddle is snug and secure, it doesn't feel like it's going anywhere while you're riding some trails.
