I've owned several mini pumps over the years and never enjoyed using any of them, they have all been worthless garbage! After a little research, I pulled the trigger on the Lezyne Grip Drive HV in the medium size. I just got done testing it on a fully deflated 26x2.35 mountain bike tire, and was easily able to pump it up to 25 psi without much fuss! This will make trail side repairs much faster and way less stressful! Just a well made and well thought out product, im very happy with my new pump!!
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.
Found out the hard way that you absolutely need this to install SRAM 'stealthamajigs'. Be generous; give the barb a good coating and put plenty on the little red guy and the 8mm nut threads. Tighten to 8 nm, which is a goodly amount of torque for something that small, and no tears. Skip one of these steps and you might not have a leak, but you'll be asking for one. That said you'd have to repair about 10,000 brake lines to ever use up the jar, assuming you never forgot to put it away properly and didn't pollute the whole batch. A little foil packet would make a lot more sense.
