I was told at the LBS today that i was too big for a 650c wheel, I have a Scott Tri-Bike that was
equipped from the factory with Mavic CXP-14's 650c. I am 240lbs, I have road the bike a little and

the tires seemed wobbly but strong.

So upon finding out I'm too fat, I started asking question that I know a little about.

1. If I get a 700c rim can i just bolt it in?
2. what do I need to do with the rear casseset after installing the 700c?
3. Whats the true benefit to getting a 700c?

1. yes your frame(I didn't have the bike with me) will accept a 700c rim you just need to adjust the brake and move them up.

2. just pull the old casseset off and install it onto the 700c hub??? O'REALY what if the hub is different?

3. You'll go faster

So i had a fuji before with a 27x1 1/4 wheel on it, to go to a 700c I had to bend the rears and change the front fork- is that not so with going from a 650c to a 700c?

How can I find out what my rear hub is so I can order a 700c and not have to change my casseset out?

I dont give 2 sh|ts about going super fast I am doing Tri-s to get fit not win a million dollars, so why change them?

How much are Mavic CXP-14's even worth?
