It's not that much reduced. I bought the 170 about 8 months ago for £130 they always have offers on but they have been pumping the original price up first.. They have just done it with my 4 year olds new bike. It showed £179.99 reduced to £89.99. The lad said it is reduced but was never the original price and was around £129.99. Reserved on line and got another £10 off too.
Moral of the story. It's good stuff well priced but not as discounted as they advertise. That said I have loads of their stuff and the warranty is good although sometimes you have to argue the matter when it breaks.
