Hey!

Anyone know how long the Pista's cranks are?

05 Pista's are 170 but are drilled 165.

What do you mean by this? I don't understand.

Here's a visual of what I mean:

http://dcc.absenter.org/foto/misc/170w165hole.jpg

Basically, the Sugino RD cranks are road cranks. They're 130BCD and can hold two chainrings. To keep cost down I suppose Sugino decided to just make them 170mm and instead of making the actual arm length 165mm, they just drilled the pedal hole a little higher, at the 165 length instead.

In the second picture is another crankset I have, Sugino RT's (beautiful cranks these are) which are actual 165mm, and you can see the hole is right at the end.

I just took the RD's off my Pista and recently picked up some Sugino 75's which I am now currently using. God, they're beautiful solid cranks.

The RD's aren't too bad at all but they're no 75's. I'll probably sell them soon.

That's crazy! I've never seen anything like that. They look goofy in the pic. I guess no one notices in the showroom?

Thanks for the pic and the great explaination. I appreciate it.

I didn't notice it either till I got home - but I knew I was going to be upgrading most of the stock parts on it. Don't get me wrong, the package is pretty damn good for the price, but I have a tendency to upgrade stuff as time and money allow.

Aesthetically it bothers me a little but there's no pedal strike issues since on a turn the angle would ne sufficient enough anyhow to clear the bottom of it. It's fine -- I wouldn't have replaced the crankset until much much later but I got a deal on some Sugino 75's that I would have been an idiot to have passed up.

You're right. I was thinking that if you drilled higher on a longer crank, it would still act like a longer crank when cornering issues arose. This is wrong thinking on my part. When cornering the thing that could strike the ground would be the pedal. If the pedal is raised (even though there is some extra crank sticking out below) it will act like a shorter crank.

Thanks again for the explaination and the pic. I've been enlightened.

absntr,

Most helpful post I've seen in a long time. That was very interesting. Thanks.

To a certain point. When you make a 140mm crank from 180mm arms, then you might have a problem.

I was told my '04 51" was 165, but I'm going to measure. That drilling business makes me mad.

Was the deal on Chicago craigslist? I just happened to be reading the bikes thing on there and saw a pair for 100 bucks. I thought about calling the guy, but figured he'd rather sell them local than ship em out.

Yes. It's actually the singer/guitarist from Milemarker, nice guy. He was great - sold them to me for $75 because I was tight with money but wanted them bad.

Why are you mad? It makes no difference in the ride or function of the bike. You probably can't even tell, unless you take off the pedals and really look.
I bet you wouldn't have noticed and cared, if it were not for this thread....

Here's the breakdown for cranksets for Pistas over the years:

2005 - Sugino RD (170 actual length, 165mm pedal hole)
2004 - Truvativ
2003 - Truvativ
2002 - Bianchi Cyclone
2001 - Bianchi Cyclone

I wouldn't worry about it if you have a year prior to 05 - in fact, I wouldn't even worry about the 05's. Makes no difference aside from aesthetics.

My 04 Pista is a genuine 165, also will only take one chainring.

They're starting to write and record a new record - out possibly late this year. Or so I was told.

Was that guy (Dave??) a messenger? I kinda recall a Reader article about his new band (Challenger?) and an accident he had when he was a messenger...

Cool, thanks, absntr. I think it is a sneaky move for the 05s though.
