Bike mudguards may save you from water/rain/dirt sprays shot up by the tires. Thankfully, no dirt marks on your back and front during/after the commute. But the dirtier parts such as the drive train and chain are still open to scrutinizing your clothing in ways that you’d squirm at the stubborn grease marks for years to come. And it goes without mention, using a bicycle chain board/guard also add life to the bike chain and the crankset that comes in contact with the dirt and sand.
SKS Chainboard made from shock resistant plastic elements and SKS-Chromoplastics-Technology(identical to SKS mudguard construction) is extremely lightweight yet rugged, thus, offering higher stability.
For installation, crank and bottom bracket have to be disassembled. You may need some external/expert help to get the SKS bicycle chain board installed on your bike. It’s suitable for trekking, hybrid, cross and mountain bikes with front derailleur as well.
