That must be nice having a very light weight bike, mine is just a 7 year old brushed aluminium laquered frame just added bits to it over the yrs wheels, hydraulics, etc but also just bought new chain, cassette, and crankset and it rides like new and although 7 yrs old now is still very clean and has only 2 tiny minor scuffs 1 of which was there when I bought.
I would love a new one not because I need one but because I want one lol but funds wont allow at mo
You are very lucky too to have a partner who goes with you my misses is not interested in cycling full stop...come to think of it not intersted in any of my hobbies but hving said that we have an 8 month old baby so it would be difficult for her to go anyway and my older 3 kids are 20, 17 and 13 and also need looking after like babies too.....
But there is no doubt about it since I been using mine regularly I feel so much fitter and at 42 yrs young my low heart rate should be around 65 to 70 bpm but is 50bpm so pretty fit now and even my 2 older sons cant keep up they have to stop and eat and drink and recover at regular intervals.
