Hi there, I need some advice on bike selection. I am a relative new comer to cycling and apart from a 6 mile round trip commute to work I have never done any long distance cycling. My current bike is a Trek 7200 with front shocks. My quandry is this - i have signed up to do a 112 mile cycle. I started training over the last few weeks and did a 50 mile trip on Sunday (any by the way my arse is no longer on speaking terms with me!) I went into my local bike shop today to get the bike serviced and when i told the guys there what i was doing they basicially collapsed laughing and said I was crazy to be attempting it on my bike. They were saying that shocks are a disaster, my bike has a riding position like someting desigened by Orange County Choppers (apparently this is not good) and basicially for what I am attempting I might as well be on a Penny Farthing. They then proceeded to show me more expensive bikes Trek 9.5 and another brand that is like the Trek but with drop down handle bars and a granny gear for mountains?? Basicially my question is this- do i need to upgrade? I only bought my current bike last year and I only want to have one bike that I can cycle to work and do this long cycle in July... Thanks in advance for advice.
