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
