Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Soma Hellyer Crankset w/ my current bb?!

Hey all, about to order parts for a conversion of my vintage Araya road bike to a ss/fg.

I ran across these Soma Hellyer Cranks http://www.somafab.com/crankset.html


They're pretty sexy, but I was wondering a few things.

First, is it worth it to upgrade from my current Sugino cranks that are on there right now?

I was going to take the chainguard off...





Second, will these work with my current BB? It is a square shaped peg that goes into the current crankset, and I think that it's the same shape as the Soma Hellyer requires.

Aren't those Soma Cranks the same as the Andel/IRO/Kazame but more expensive?

Yase.

However, the Andel only comes in black, and the IRO only comes with a 3/32" chainring, so Soma gets away with it.

Hmm. So I can use them but the BB might not be long enough? How can I measure this?

FWIW I can get the Soma's for a great price, so it's not that big of an issue.

Also, is it worth it to upgrade? I ran across this posting somewhere else, http://forums.roadbikereview.com/arc...p/t-64065.html

It was regarding which chainring to use if I am to keep the current crankset. It looks like I might not have many options in this regard. According to certain posts over there, you can't remove the big chainring, etc.

I'm thinking the BB will be too long, not too short.

Hmm, I'll post some better pictures later. This damn build is getting more and more expensive by the day! And I haven't even ordered anything yet!

Alien sells those cranks too, for $89 with a less sexy chainring. You'll just probably have to see how long the spindle is and change it out, or have a shop measure and do it properly.

That said, I LOVE those old Sugino cranks! It looks like the guard is riveted though - have you tried to take it off yet?

Hmm those look pretty nice, and that's about the price I was lookin' at for the Soma's.

Like I said in OP, I don't hate my current cranks I just worry that I won't be able to run a clean chainline, remove one of the chainrings, and they won't be able to handle the stresses of riding fixed (though I only way about 135 so...not stress from me!)

The chainguard is screwed on so I think I can remove it. Think is the operative word!
