Additionally, without a lot of maintenance, winter will destroy your bike.
I got my current year round bike in aught 7, it's a specialized tri-cross elite.
I need a new bottom bracket not quite every year, I'm on my 3rd front rim, 2nd back rim, and I get a new chain and rear cassette every year. And 3rd or maybe 4th set of brake/shifter cables, but I don't treat my bike as well as I should. My repair total this spring was something like 800 dollars, should have just bought a new bike for it, but it ended up being 3 seperate repairs over a month.
I'd say I average about 300-400 a year for repairs, but it's also a bike where every part is 50+, and I have a shop do the vast majority, so I'm paying labor as well.
