|That's 8 inches of seatpost showing. Would I benefit from a new carbon fibre seat post. Right now I have the Weyless two bolt made from 7071 aluminum.
Also, at 240lbs, would I snap it in Two....

|I have a steel frame (61) and a Thomson Elite AL seat post. I'm a clydesdale too, and I was a bit worried about cracking a CF seat post. But alas, I didn't feel the need to put a CF seat post on my large steel frame that was giving enough as it is.|

|I'm not sure what your question is exactly. When you say "would I benefit?..." do you mean strength, weight, other? If you have 8" of seatpost and its a standard frame then your issue is a too small frame not the seatpost. If its a compact frame and you are looking for a good post then yes there may be a marginal weight benefit to a carbon post but hardly worth dropping >$100 on IMO.|

|mountain bikes expose much more than that and don't break. I use Ti in my very compact geometry roadbike. It gets rid of the bite of small bumps.|

|It's my first road bike and I kind of stumbled onto it. I have a quill 90mm x 105 degree stem. So the bike fits fine. When I changed the saddle to the Selle Italia Genuine Gel Prolink. I could feel the absorption of the bumps. From some of the past posts, it appears that I have enough seatpost showing, that it might make a tangilble difference. Interested in getting a bit of feedback...Thanks|

|The poster should try reading up on fit a www.cyfacusa.com.
Although the frame may be rideable, I doubt it fits by normal roda bike standards. Way too much post showing and a short stem. Makes no sense.

|I bought a new hybrid 9/22/02, thinking I would ride 2 or 3 times a month if I was lucky. It had a XL frame and 26in tires. I rode it a couple of times and wanted to go faster. The LBS took it back and gave me a better hybrid with a bigger frame and road tires.
A funny thing happened, I started riding it every morning before work. I got up to a 12mi ride before work, and was loving it. I still wanted to go faster, but at the same time, I didn't know if I would like the drop bar road bike experience.
Along comes this brand new 01 Nevada City for $350.00. I bought it, figuring that if I didn't like the road bars, that I could put a straight bar on it and change the shifters. My frame size has gone from a 22in,23in, to 61cm which is about 24.4in, so I new I was headed in the right direction.
I was looking at a 63cm Cannondale, that was a lot more money, so I bought the LeMond. The original stem was 140mm and had me stetched out too much. Since Dec, I have put over 2000mi on the bike and am loving it.
When I upgrade sometime in the future, what size frame should I be looking for. I am 6'4" with a 36 1/2 inseem, using the phone book in the crotch w/o shoes. My shirt sleeve length is right at 36 1/2 also. By the way, I weigh 240lbs. I have lost plenty of ass since I started riding, and hope to be down to 225/215 by the end of the year.
I am learning as I go along, and have picked up much useful advice on this board. Your thoughts and hints are greatly appreciated

|These would be the sizes most commonly recommended. As I mentioned, www.cyfacusa.com has good info on fitting.
What I recommend for measuring inseam is to use a bike with the wheels blocked up to a height the causes firm crotch contact when you stand over the frame in bare feet, wearing cycling shorts. Measure the height from the floor to the top of the top tube for an accurate inseam. Multiply by 2.54 to get centimeters. The standover height of a properly sized frame will be 3-6cm less than you inseam. Big guys can usually have handle the most standover clearance. I keep mine at 4cm less than my 83cm inseam.
The frame size measured center to top is usually 28-30cm less than your inseam. If you look at frames measured center to center, the frame "size" would be 1.5-2.0cm smaller.
Another reference dimension to consider is the height of the saddle above the top tube, measured near the nose of the saddle. A height of 16-19cm is common. Mine is 17cm above the top tube and yields a handlebar to saddle height difference of 9cm. If the saddle was 19cm above the TT, then the height difference would be 11cm, which is pretty extreme. Once again, big guys can usually handle more, due to their long arms.
