Holds everything you need for road riding. Secure once installed but I feel like I have to tighten it down occasionally, maybe because it's still new or maybe because it loosens on its own. Not easy to move from bike to bike. Not super easy to get things out once installed. It does seem highly durable and well made.
It's sleek enough for my roadie sensibilities.
For what it's worth, in +30 years of being a 'roadie', I'm not sure I've ever found a saddle bag that I would call great. But I can't bring myself to call this one great either and it's quite pricy.
Mounts easily onto my Salsa Journeyer using the given bolt spacing and the bag length is perfect for wrapping around the stem. I took a star off because of difficult packaging of the instructions to the bungee strap and no bolts to mount the bag. The bag is made of soft material, so I could see someone over stuffing it and possibly causing knee issues if the bag bulges out. Although I have a 60 cm long wheel base bike so it is not an issue for me as my knees come up near the end of the bag. The bag width is about the same as my top tube, which is what I expected. Just enough for my carrying purposes (bars, suntan lotion, day-use stuff).
I'd been using the old style Ortlieb mini handlebar bag. While it's satisfactory for most of my purposes, it had several drawbacks, chiefest of which was that by using the front of the handlebar, you have to find alternative locations for your front light. When you add up the bag, the bag mount, and the additional accoutements to mount the front light, it's actually substantial weight. On the tandem it doesn't matter, but on my single bike I really would prefer as light a setup as possible, while still making it possible to mount a radar tail light.
The only model I could find that fit all those requirements was the Ortlieb Saddlebag 4L. I ordered one and discovered to my dismay that the mount didn't fit the Ritchey WCS saddle! Fortunately, Pamela Bayley had sold/given me a smaller Ortlieb seatbag and that one came with a mount that worked. (I would later replace the screws that came with the newer bag with ones that work) Since all Ortlieb saddlebag mounts are cross compatible it was no issue to use them. My complaint about this design is that it's unnecessary --- I would much rather have had velcro wings which would have been less finicky.
The saddlebag slides onto the mount, and ties to the seatpost using a velcro strap. I was worried that I would feel the saddlebag with my thighs while riding, but to my surprise this turned out to be a non-issue. The drybag style flap clips off to the side and by tightening the straps it becomes narrow enough that thighs clear the saddlebag with no problems. One disturbing thing about the bag is that invariably there's sufficient air in the saddlebag to make it bulge a little, so sometimes it takes a couple of tries to get the air out. A valve would have been useful though that would have increased the weight. As a result of this air, sometimes that bag will rattle especially if it's not completely full.
When I go on a really lightweight ride, I replace this saddlebag with a mini bag that uses the same mount and has much less volume. It's little enough effort to switch that I do it as a matter of course. But for bay area riding the 4L bag is what you want: you can put in a windshell, arm and leg warmers, and snacks and tools for an extended ride while still having room for your radar. If you pack really light it might even suffice for an overnighter, though that's not in the cards for me as I would need to pack a CPAP machine and this bag just doesn't have sufficient volume for that.
For commuting, this bag will NOT fit any laptops. But bikepacking style saddlebags won't fit any laptop anyway. For carrying a laptop you still want the traverse style saddlebag.
The bag is a little expensive but it did everything I wanted it to do. Recommended.
To get the catch out of the way, this bag is a pain to transfer between bikes, because the key to its (excellent) performance is the long, broad velcro strap which must be carefully threaded through the seat rails and the loops on the bag then cinched. It takes too long to move it from one bike to another, for that you want the Ortlieb. But, once this bag is on, it isn't going anywhere, or rattling, or otherwise calling attention to itself. And the lid provides the perfect surface for sewing on a Garmin mount for your Varia radar at the proper height (the bag wasn't watertight anyway!). And the multitool has its own pocket which means you can get at it (fairly) easily w/o opening the bag, you may have to loosen, not undo, the strap. An unsung hero of the seatbag pantheon!
