Hello,

I'm looking to buy a Klickfix truss (rated for 7kg) and a Freepack Meta II Klickfix backpack to use with my Mu P27. I've noticed however that the Klickfix attachment is made of plastic, and was wondering about it's strength.

I'm going to carry around 4kg on the backpack (mainly my lunch, laptop, and the weight of the backpack itself). It's well under the 7kg limit, but what is worrying me is that I have a notable descent in my commute and have to pass over a couple of speed bumps where I usually slow down to about 20kph.

I'm worried about the Klickfix attachment breaking over time due to the repeated stresses everyday. Has someone had good or bad experiences with Klickfix? I really don't want my laptop crashing into the ground... or me falling from the bike at high speed if the backpack falls over the front wheel

I bought a klickfix front basket mount for my friend's bike a while back. They seem to be made very well, with good plastic. I don't think it'd fail any time soon. I've also seen old klickfix mounts on bikes that have long lost the basket that it used to hold. The mounting adapter still worked fine.

I think you'd be fine.

Thanks, I have placed the order and I'm hoping to get them soon

I have a KF bar bag mount , Its fine, so is the one on the seatpost .. weight is supported by whole mounting block

the little tabs on the top edge just keep it on (Ortlieb bar bags work on KF mounts)

have their square plate mount (they make a backpack with a mount recessed in the back)

and their Wire support , those are featured on many Baskets and Bags in the KF Line..

the back pack has its own mount I see.. https://evobike.hu/sajatfiok/kepek/pb...cnfjltvkm.jpeg

I have a Klickfix Freepack Sport backpack and used it for several years attached to my Brompton while commuting. The Klickfix plastic adapters are extremely well made and durable, as is the Freepack. Never had a problem and I'm sure there were times when I really loaded it up.

I'd be more worried about the aluminium truss developing a crack than the KF plastic. Not saying they would, just that it's more likely.

had the old Dahon replicas break ..similar design . but NONE of the original klickfix

I have an 8 year-old Freepack City which I still use although it's a bit worn out. I also have a newer Freepack Meta II. Both are great for carrying the laptop + adapter + book and more stuff. The Meta is larger though. I use the bag on my everyday commute and it's great.

I had the Klickfix truss in the past but now have the Dahon one, it's made of metal (aluminium I think) and IMO it's more stable, but both are ok.

One of the benefits of the Klickfix system is that it is Ortlieb-compatible. I also have an Ultimate 5 bag that I can attach to the truss.

Oh, and by the way I also have some speed bumps on my route and the truss handles them quite well :-)

Well, I've finally got everything installed and I'm not quite satisfied.

The Klickfix adapter seems quite solid and handles the speed bumps without problems and the Freepack Meta II backpack is well built and has lots of useful features. However, I'm having some problems with the brake/shifter cables and steering.

The first problem is when the luggage truss is empty. Brake and shifter cables get caught in it when steering, making it dangerous. With the truss came a velcro strap to avoid this. However, With the strap fitted I can't lift the handlebars high enough to fold the bike, so I have to remove it everytime, and put it on again after unfolding. I think I can come up with a better solution, so this is not such a big problem.

The second problem is that the backpack is really hard to attach, as you have to tilt it backwards for it to "click" in the luggage truss. When tilting it backwards it strikes the handlebar post so it's really difficult to attach without folding the stem. Moreover, when attached, the brake levers hit the top of the backpack when steering, limiting the steering ability (and I'm worried about damaging the backpack too). This is not a big problem when riding in most conditions as it occurs mostly in tight, low speed maneuvers, but I don't like it and I'm worried it will damage the backpack over time. The only solution I've found is to raise the handlebars at their maximum position, where they barely clear the backpack. However, this position is really uncomfortable, especially when climbing, which is something I have to do on my daily commute.

Hmm... You might want to consider attaching your backpack to your seatpost instead of the handlebar stem and using klickfix's extender (see below). This is how I had mine set up on my Brompton. I preferred the backpack up higher and behind me, as I felt that way it did not add drag. Only drawback is that with the adapter attached to your seat post you won't be able to lower it all the way, just a few inches less.

Thanks. This is the option I am considering now. I think I'm going to keep the truss anyway to have even more carrying capacity.

I originally thought the luggage truss was better as it allowed better weight distribution (the weight of the backpack sits lower) and the fact that the bike doesn't fall over when the bike is on the kickstand. I don't care at all about drag when commuting as I usually ride at a slow pace to avoid sweating.

Maybe there's a way you can use the extender on the truss.

Mmmm... I don't think I can use the klickfix extender with the Tern truss, but I'll have a look at it.

Thanks!
