Ride your full-suspension mountain bike long enough and you'll eventually need to replace the DU bushings on the rear shock. With the right tool, the job is actually a lot quicker and easier than you might imagine. So at the next hint of play or creaking at your bike's rear end, grab some fresh bushings and the DU Bushing Service Tool from Abbey Bike Tools and you'll have new bushings in your shock and be back on the trail in no time. Abbey crafts this compact tool out of stainless steel and it allows you to remove and install 1/2 x 1/2-inch bushings into your rear shock's eyelets without resorting to archaic and potentially damaging hammer, punch, or vice methods. Using this tool just once will pay for itself.
