Not one to write reviews but this is great...my old Trek 728 roadbike I bought in '82...the frame&fork is the soul of a bike and it has soul... I wore out and replaced everything else until it is now a great single sprocket (Shimano Nexus 7) Brooks saddle and fendered flyer, racks and baskets front/back, aerobars...but the chain needed protection from the elements, as it needed all these years. I looked - chainguards just aren't around because they aren't appreciated for their utility and other aesthetics. Getting an oily trouser leg is an issue, but just about any fool can avoid that...but a bicycle chain is exposed, high maintenance, has lots more moving parts than all the rest of the bike and should be protected from road grit or it'll get chewed up. I just replaced the rear sprocket and front chainwheel with a 48 tooth and saw this German SKS chainguard from Niagara might fit...it fit beautifully and my ride just went up one full level. I am ecstatic. Thanks.
