On my bike the rears are almost worn down after only 100 miles or so, the fronts not so much.
I use the clarks blocks, and have found them excellent. Probably done around 4000 miles on a set now. They are getting down but still ok.
Totally agree, yes you can cycle on a budget.
But.......,buying better stuff over time usually results in the same outcome, you just don't feel like you are spending so much at once! I dread to think what I've spent over the last 18 months on my road bike with accessories, upgrades, garmin, clothing etc, probably easily over £1000 with the bike being only £400 of that, and I'm a tight git, I just can't stop myself.
Actually probably more like £1200.....
Then there's the TT bike and wheels I bought a little while ago for another grand.
Oh dear.
But also
I think you would call it mixed emotions.
