I am in the middle of a cold weather tear down / deep cleaning of my Clem L. This project started with ordering a new chain & large chainring to replace worn units. I start taking things apart and am unable to stop. Bottom bracket felt crappy so took it out and everything was just really dirty so I did not stop until I had a bare frame. In the process a couple of interesting things were discovered. First item pertains to the new chainring for my Silver wide / low crank. Its aluminum of course as described by Riv. What is interesting is the original was steel and a relative boat anchor! This discovery led me down a rabbit hole of weighing everything. I have never been a weight weenie even less so since getting my Rivs. But, armed with a very accurate scale and a driveway covered in snow I started taking notes... That aluminum chainring saved me 85 grams weighing in at a scant 58.5 grams vs the originals 163.5. Held in ones hand that felt like at least a pound. I am curious about when Riv started making the larger rings out of aluminum? The size 52 Clem L bare frame with headset cups installed weighs 2,932 grams or 6lbs. 7.4 ounces, topping my list of things I did not need to know. The bare fork is 1,063 grams or 2lbs. 5.5 ounces. I feel certain the fork on my large Gus is twice that! My 650b cliffhanger wheels built with 36 hole deore hubs shod with Simworks Homage tires mounted with tubes come out to 4lbs. 7.1 ounces rear and 4lbs. 0.3 ounces front. Cassette and q.r. skewers not included. I will be weighing everything else before assembly but probably will not bore the group with the details. I will say this; I am very interested in why my Gus weighs at least 32lbs. while another guy's weighs 26! I must find out why.:)
