I've done some long distance riding on it and some climbing centuries and doubles as well. I am looking to lighten it up before RAAM June 2015. We are doing 4X tandem relay.
One thing in particular I need advice is in converting the triple to a double. Currently I ride a triple with a 55/39/28 Sugino and 11-28 cassette. I hate the triple and since this hasn't been my primary bike I only had to deal with it every few months. But I will be riding this bike more regularly between now and June.
So my questions are:
how much lighter are 2X cranksets than 3X?
What brands make quality light 2X cranksets?
Does someone have a link to a chart with verified weights of these cranksets?
There are more questions I want to ask but let's start with the crankset.
To be honest I was a bit in "shock and horror" as I read your post. Unless you are a 120kg/500 watt output uber competitive team, I can't see how the loss of 50g in a chainring is going to make a heap of difference? Lose the breakfast 3 days running before the comp and this will have more of an impact.
