I have a straight forward commute. With additional rides, I'm probably doing between 70 and 80 miles a week.
After using different mountain bikes for years, eight months ago, I was told it would cost £150 to repair my bike, so I decided to buy a single speed/fixed gear. The idea being that there's less to go wrong. Low maintenance - less expense.
I bought an SE Lager for £435. It's a lovely bike, and a very smooth ride.
However, after six months, the Thick Slick tyres lost all puncture resistance. I was getting a puncture a week!
I replaced the tyres with Marathon Plus for £60.
I've just taken the bike back to the shop I bought it from, to have some repairs carried out, and have been quoted £130!
I realise that I'd save a fortune if I learned how to carry out these repairs myself but that's just not going to happen.
I'm starting to think that I'd be better off buying a cheap bike, riding it into the ground, until it gives up the ghost, and then buying a another cheap one.
I see Muddy Fox Mountain bikes advertised for £150, or those Chinese Single Speed/Fixed Gear bikes go for under £200.
Moan, moan, moan...
