I used to cycle a lot but car pooling to work put a big dent in that. We were in the Pinery Provincial Park on Lake Huron for a few days this week and we usually bring our bikes with us. Did fine the first day but the hill climbs the next day killed me... so out of shape. Now that my wife is retired I need to get back into cycling to work.
I have a Miele road bike that one of the in-law's tenants left behind. That was a score! Chrome-moly frame, elliptical front sprocket and Shimano derailleurs. It was missing pedals so I just had to buy those and later replaced the rear rim which was steel, so it's all alloy now. That was royal PITA, removing all of the spokes and gear cassette. Front forks are rusty and paint is battered so no-one knows it's a decent bike.
Thinking about some new bikes as well, though, better suited to hard pack trails. MEC has some really nice light weight bikes. The ones at the bike shops are crazy expensive, like $2k-$5k. I'm not entering a triathlon!
