Any front rack that mounts to the brakes bosses is going to be a little fragile. I would never put more than about 5-7 pounds on that kind of rack. Its a great rack for having an extra space to strap light stuff light a sleeping bag, one man tent, or thermarest. I would not used it to haul anything dense as brake bosses are just not designed for it.

If you want something more substancial but short of a FULL front rack like the jannd extreme or sulry nice right, you should consider the Nitto min front racks. They make several different version. The one I have uses padded hose clamps to mount directly to your front fork blades without mounting mounts. Would that solve the mounting problem with your bike?
