My Chain Tensioners

Here is a Cycletherapy creation that I used a couple years ago. It is a pair of Profile Chain tensioner s in anodized blue. The original washer has been replaced with a Surly tuggnut qr washer (if needed). It needs to be sanded a little bit around the edges so it would fit into the chain tensioner s.

Part - Weight - Material
Original Washer - 4.1 grams - Steel
Surly Washer - 2.6 grams - Aluminum
Chain tensioners - 21.3 grams - Aluminum
