Equpiment Review: Bagman Saddlebag Support

After years of using a saddlebag without saddlebag support (and wearing holes in my Nelson Longflap as a result), I finally gave in this year and bought one, mostly because I had switched away from my beloved Brooks B-17 in favor of a plastic saddle that won't go bad in the rain. (This also saved a ton of weight)

Bagman saddlebag supports are apparently quite hard to find, but a call to Wallingford Bikes turned one up. I ordered one without the quick release (because Ti versions weren't in stock), but the one that showed up turned out to have the quick release feature instead (which weighs a bit more).

The support snaps onto the saddle rails with an allen screw, and installation takes no more than 3 minutes, even if you loc-tite the assembly. However, the Bagman has a fatal flaw, which is that the struts supporting the bag proper are mere rods that slip into a hole in the saddle attachment, which is then held entirely with friction by a couple of small screws (about 3mm in diameter) and a bolt.

Whoever designed the Bagman has never done a major bike tour involving rough roads or rough stuff, because even though I applied loc-tite to all of these screws, after about 15 days of rough riding (or 3 months of daily commuting on my Munich Commute) and the rods would slip out. The first time this happened it was in heavy Munich traffic, which was quite disconcerting. Fortunately, the design is such that you won't lose the small screws if that happens.

Since then, I've tightened the screws periodically, and just before any long tour. Even so, during this past tour, my bagman came loose in this fashion not once, but twice. The proper solution is to undo all the screws, mark the rods, and then put in divots in the rods to prevent this sort of motion in the future. But seriously, it's poor engineering to expect the customer to put in fixes for obviously bad design.

The quick release feature also turned out to be quite a bit of a mixed blessing. First of all, it truly is only a quick release --- putting the bag back in is just as laborious as the pins aren't precise enough for you to thread it through and already looped leather strap --- or at least, I can't do it. Secondly, the pins are basically tied to a screw tip which pushes back against springs. Guess what --- they unscrew themselves with sufficient bouncing on the saddle, and come off. If this happens during a tour when you happen to drop the pins and the springs, good luck! So on a tour you have to check these pins for tightness and periodically tighten them.

I cannot therefore recommend the Bagman for serious cycle tourists who are not mechanically savvy and willing to perform the modification. This is a pity, since I still think saddlebags are a better solution than panniers for light touring, but given my need for CPAP therapy, perhaps my days of light touring are past. The search for a better solution continues...

Bill at wallbike is a really nice guy. I used to be on the board of the Cascade Bike Club with him until he moved.

The Nitto saddlebag support that Grant sells also sucks. Similar problem--it's held up by friction alone.

The set-screws are actually M5 set-screws, despite how small they may appear. Replace them with M5 bolts of your choice. If the sides of your saddle prevent easy access, you may want to use hex-head bolts instead of socket-head (i.e. allen key) bolts. Regardless, you will be able to tighten these bolts to an appropriate torque, such that they never loosen. I don't use Loctite on mine and I've never had a problem.

My (Ti, non-quickrelease) bagman fell apart two days ago!

Just got a Nelson bag for my gf and was looking for info on bagman and came accross your review. I second that Bill at Wallingford is extremely helpful. On the problem with Bagman supports, it seems like this could be fixed by running the struts through the clamp and tapping a thread on the end to place a washer and stop nut. Is the clamp like a seatpost clamp?

You won't need to go that far. Just put a dimple in the end of the rod and then screw it as tight as you like with some big 5mm bolts. Pardo just made that fix for me last week, and we'll see whether the problem goes away. As Pardo says, it's a British product, expect to have to make the mechanical fixes yourself. :)
