Glad I switch to 180mm cranks!

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Glad I switch to 180mm cranks!

I converted my Bonty Race Lite 175mm 52/42/30 to the new Shimano Dur-Ace 7800 53/39 exo-bearing b.b. with 180mm crank arms and I am please with the results. It took a little getting used to feel-wise, but now I can more effectively use my long-assed legs and can power up those hills better!

Anyhow, I know I'm violating an OCP code for mixing Italian shifters/derailleurs/brakes with a Japanese drivetrain, but f*ck it, it had an American drive-train on before, so what the diff?

I got an incredible deal on it off of ebay (basically got the b.b. for free) and I believe the 2005 Dura-Ace 7800 is by far the lightest and stiffest crankset out there. My mechanic says that the new external bearing bottom brackets are a mechanic's best friend as far as maintenance and they are very strong, which is important to a big rider.

If Campy ever gets with the 21st century as far a b.b.'s go on the Record (offered in 180's) I may convert someday, but Lemonds require an English threading anyway, so it probably won't happen.

I have to agree with the stiff part about the new Dura Ace. Make sure you have an extra chain because those tend to go pretty fast on the 05s. Mash it Up

I have a 38 inch and run 177.5 Dura Ace cranks with a full Campy record drivetrain and love it. I would have used 180's but my other road bikes are 175's and I wanted to keep them consistent. I do use 180's on my single speed mtn bike though.

I think you're right about the Dura Ace cranks being the best out there at the moment, although if Campy carbons came in 177.5 or 180 I would have still used them, just cause I'm a die hard Campy fan, and I think cranks stiffness is often overrated.

BTW. Campy's are available in english and Italian threading, as are most bb's aren't they?

Yes, it all hinges on the bottom bracket you get for the campys

Having been riding 180's for about 15 years, I can't under stand why any body over 6' +/- would ride anything shorter.

With regard to Shimono vs. Campy you can keep the Elephant-nose-lookin butt ugly crankset! I don't care how stiff it is. As for BB,s I will stick with the square taper thank you very much! And...the Campy comes in English threading and always has.

I could not believe the difference when I switched to 180 mm cranks (just ilke you I went DA10 180mm cranks). My inseem is 38 inches, 6'6"... I tried the record 180mm alloy cranks but I did not really like them as much as the DA... although they are very nice and not flexy.

Never thought of elephant nose. That's a funny observation. My first impression of the Dura Ace crank was of a circular saw because of the metal under the chain teeth.



As for square taper and 21st century, it doesn't seem to slow down Petacchi, Boonen, or McEwen. Petacchi and Boonen even use the alloy crank.

tall guys really should go custom (unfortunately)

I am 6'5" with a 36" inseam. I currently ride a 180mm tune BB/crank. FastFoot i think. I quite like it, I believe its 200+ grams lighter than shimano. Before that I had a custom 200mm crank from hscycle.com. I highly recommend the longer crank. With 175s, I always felt like I was tiptoeing.
