Last month, my LBS had their big, annual blowout sale, and I scored some Trek Interchange panniers for my commuter (Surly Cross Check, if anyone's curious). I'm a pretty aggressive rider on my commute - I'm often up off the saddle sprinting to keep up with traffic, merge, whatever. When I do this with the panniers, though, I have problems with them swinging around, falling off, etc. Today, a bungee cord that was hanging out of the mesh pocket on the back got caught in my spokes, and pulled the pannier into the wheel!

They use a plastic knob that's supposed to hold them to the side of the rack, but it doesn't seem to work well, especially when they're mostly empty, with a single heavy item (like a lock) flopping around in the bottom.

My question: is this an inherent limitation of all panniers, or did I just get crappy ones? If it's an inherent limitation, I'm going back to a messenger bag or backpack, because I don't have a relaxed, Copenhagen-style commute. Riding less aggressively isn't really an option.

If it's just that I have crappy ones, what are some better (more secure) ones I could use? I'd lean strongly toward Vaude, because I can get a deal (their distributor sponsors my club), but I'd like to hear if anyone has some real input.

Question- do you have a matching Trek/Bontrager rack that utilizes the "Interchange" system?

pretzelface

Yeah, it's the "Interchange" rack. I don't see exactly what differentiates it from any other rack, other than having the little tab on the pannier that clips to the top, though.

Then again, I'm a total noob when it comes to racks and panniers (otherwise I wouldn't be asking!).

That's a common issue with Trek Interchange panniers. I personally know two people who have crashed because this very same issue. I'm very surprised their engineers let a design like that through, and even more surprised their lawyers haven't made them remove them from the market. Maybe someone should phone Ralph Nader.

I've never heard of the problem with others.

Although I have had a bungee leap out of my open-top grocery pannier once, and wrap itself around the cassette. Pure rider error, that one.

Is there anything bad about the rack I should know about?

No, some panniers can be installed very securely. I think Ortlieb panniers have the best pannier quick lock system and panniers overall, but it looks like Vaude have cloned (or licensed?) Ortliebs attachment system (they call it DMR instead of QL), so they are worth looking into if you can get a discount. The "Aqua Pro" series is the one I would buy because of the simpler and faster lid system.
No personal experience with Vaude, but my Ortlieb panniers simply can't fall off once they are secured correctly when put on. Even if the lower attachment wasn't put on correctly, the top attachments locks the pannier safely to the rack.

If you don't carry that much consider getting a front version (the work just as well on a rear rack), since they are smaller and more aerodynamic.

A good rack is also essential; get one that support the pannier so it can't swing into the spokes. This Topeak rack is an example on a decent rack: https://www.topeak.com/products/Racks...tDXTubularRack

Don't be ridiculous. Of course it is. You just don't want to hear it.

There are more secure panniers out there, but be prepared to spend more on them.

Care to rethink that?

Until you can find a way to cinch down the bag securely, you might just wrap a bungie around the bag and rack to keep it from flopping around.

I ride somewhat aggressively as well and my panniers --empty or full-- always stay in place, so the two are not mutually exclusive.

Ortliebs... depending on what you have to haul, the classic Front Rollers (small) or Back Rollers (large). These things are virtually water and dust-proof.

If the real problem is the rear of the pannier swinging into the spokes, then a better rack is the real answer. Racks with a bar further back and down to prevent the pannier from hitting the spokes will help with any pannier.

I have this rack on my LHT:

I'm using some cheap panniers, and haven't had any problems. On the downside, your interchange panniers probably won't fit.

I used to carry my laptop in interchange panniers on an interchange rack. I dropped that laptop in traffic several times, and wrecked fenders twice due to the pannier hitting the spokes. The laptop has survived, but I won't use that pannier/rack combination again.

SlimAgainSoon

I'm new to panniers but just bought a set of Ortlieb Backrollers. Nice design, the way they fit onto the rack quickly and securely.

I don't know what you would have to do to knock off one of these. Certainly more than aggresive riding.

You need a rack with a dog-legged rear stay like this. https://www.rei.com/product/780549 I have a similar Radical Explorack that cost about $40. With my previous rack I swung the panniers into the spokes several times when making sudden swerves. I now use a trunk bag on top of the rack because I used to carry too much in panniers. I keep the U-lock permamently at work.

tjspiel

I've got limited experience with panniers. I can't imagine how mine could swing into the spokes even though my rack has no dog-leg. Mine have a stiff sheet of plastic against the inside wall though. I'm assuming some panniers don't have anything in particular that keeps their shape?

Another vote for Ortlieb.

I'm a pretty aggressive rider as well, lots of sprinting and holding or pushing my way into lanes when I need to, and the set of Ortlieb Front Roller Pluses I experimented with a for a month or so on the rear rack on my Giant OCR never came off and never felt even slightly loose. Rock solid.

I ended up not liking panniers for other reasons, but when I get my touring bike (any day now) I plan on going Ortlieb.

There are several effective pannier mounting systens: Ortleib, Rixen&Kaul, Vaude and others.
Some are quicker to release than others, which is a consideration for commuters rather than tourists.
Generally they are all better than hook and elastic.
The bad mounting systems have hooks which, if the mechanism snaps, cease to act as hooks. This is a Bad Thing since you pannier will pivot down into the wheel.
The anti-sway devices at the bottom should have a good length of hook to get a grip of the lower rack leg.
As stated, with a good stiffening on the back and base, the dogleg strut is not required.

I have an Arkel Bug that I attach to a Soma Deco rack on my Crosscheck. It was pricey, but it's a very solid pannier. I haven't had any issues with it slipping around.

I think the biggest factor in stability is the attachment to the side of the rack. On the OP's panniers, that's accomplished with a plastic knob. In my experience, those tend to slip around and off with unstable loads. I had similar problems when I used some old REI panniers that were set up like that. However, the position of the knobs was adjustable, so you might be able to move yours around to get them where they are a little more secure.

The Bug, OTOH, is attached to the bottom/side of the rack with a hook and bungy. Much more secure.

Riding aggressively shouldn't be an issue if the panniers are properly attached.

I've got a CrossCheck with Axiom Streamliner rack (narrow mounting) with Ortlieb front packers or rollers. I'll strap a bungie from the bottom strut of the rack over the pannier to the top to keep it flat when unloaded (otherwise it kind of inflates into full size) and loose items like a lock from bouncing around. Most of the time I ride with just the left pannier. Absolutely solid. The only time it's noticable is if there's a lot of weight, then it's like riding with a lot of weight but it doesn't flail around.

https://www.axiomgear.com/products/ge...reamliner-dlx/

I installed it with flat ss straps common to Blackburn and others because the Axiom mounts stick down to far into the fenders. The narrow rack is very, very stiff.

WillynHook

Another vote for Ortliebs. They are very secure on my planet-bike eco-rack, don't bounce around, waterproof, and fasten every-which-way possible to the rack and to each other. Maybe an image helps?

Cheers!

I like panniers better than a rack-top trunk bag when I'm standing out of the saddle for power. The pannier puts the weight lower on the bike so it doesn't feel so top-heavy when my hands are doing the work of keeping it upright.

Commodus

I looked at all of them and came down to Arkel VS Ortlieb. When I compared them side by side at my LBS, the Arkels seemed to me to have much better attachment system.

So, I recommend an Arkel bag! They have lots, whichever fits your size needs.

RI_Swamp_Yankee

Detours Uptown have a ratcheting hard plastic strap that hooks to the bottom of the rack. It ain't going nowheres once it's locked on. Relatively cheap, too (compared to Ortleib and Arkel, anyhow.) Make sure you take it for a test ride... heel strike may be an issue if you have big feet and short chainstays.

pretzelface

Thanks for all the recommendations - as I said, I'll be going with Vaudes, since I can get them at a deep discount through my club's Magura deal, and buy a nicer rack if necessary. I'm not ready to give up and go back to the messenger bag just yet!
