Hi everyone,
Just wanted to update you after all you help and advice, both bike-related and relationship-wise, lol!
Well, you guys gave me a great boost and as a result I turned into some super-assertive ninja and told my partner to back off and I'd be choosing and buying my own bike without his input!
Lots of online research and solo shop visits followed, followed by a false start on a joint visit to a shop where he was told he could come in and look at the men's bikes, but leave me alone in the women's department. Of course he couldn't resist joining me, but as soon as I heard him sucking his teeth behind me and muttering 'ooh you don't want that one!', I aborted the visit instantly and calmly walked out - I think that's when he knew I really meant business!
By the time I had narrowed it down to two bikes, he was ready to come with me and actually LISTEN objectively to the very experienced cyclist salesman. Some of his objections to a particular bike were addressed during the conversation and he actually learnt some stuff he thought he knew, woooo!
Anyway the upshot is, I'm the very happy owner of a Giant Liv Invite 1 - a cyclocross bike. T'is a beauty! And what a difference!! I'm soooo much more confident on it - still terrified on the road but no longer terrified of my ability to control the bike. Ancient muscle memory kicked in and I just feel at home on it. Now I feel I can progress at last and enjoy cycling like I used to years ago. And my partner...? Thinking of buying a cyclocross bike for himself as mine seems such fun and flexible! Lol!
Thank you all for your encouragement and advice - much appreciated.
