Hello there.
I've had mine since 2013, and I've never serviced it - but mine's v. low mileage - I'm still on the original brake blocks! On its second chain & sprocket.
I think it all depends on how much exposure it gets to road salt and the like.
Where are you studying btw - is it The Morley?
Just joined your silly clown bike club, and if you see me around town on a very shiny silvery s6l, say hello.
Hello Jurek.
BTW, do I really need to service the main hinge on the rear triangle thing twice a year ?
