options for 180mm double crank?

[erikv]

I'd like to try 180mm cranks on my Redline Conquest cyclocross bike.
I am 6'5" and have very long legs, so I think I can handle it, and I'd
like a little more leverage to get through the mud.

I see lots of MTB crank choices, but they are triple chainring and I'm
assuming they can't be used without changing my BB and increasing the
Q factor. Maybe that wouldn't be so bad but then there's also
chainline issues, I suppose.

All I have seen for double cranksets are dura ace and campy record.
I'm wondering if there's any alternatives? All I really want is the
cranks themselves - I have 130mm chainrings. I'd like to find an
option for under $100. Impossible?

Talk to someone who uses 180's. Call Peter Dreesens @ Tailwind Bicycles @
610.287.7870. He will either sell you one of his or at least let you know
what is on the market.

Most triples become doubles when you take off the inner ring. In
other words, if you buy a triple that can be double-ized by removing a
ring, and the double version of the crank has the same spindle as your
crank, then chances are very good that you can run the triple sans
inner ring on a double spindle and the chainline will be perfect.

_ If you can stand the switch to 110mm rings, you might try
looking for "Euro BMX cranks", you can often get these very
cheap. Bulletproof is very cheap $35 without rings. I'm not sure
if they come in 180mm in aluminum alloy, a quick google only
shows 180mm in Cromoly.

Finding a pair of crankarms that are 180mm length *and* fit 130mm
chainrings is going to be very difficult. Dura-Ace is one option, but
that's going to bust your budget. I think TA Alize comes closest:
http://www.peterwhitecycles.com/alize.asp

If it were me, I'd pull out a set of Shimano MTB arms from my
collection and put on a pair of rings- but then I've got gobs of 110mm
bolt pattern rings.

Nope. The Redline BMX cranks will only fit "American" style bottom
brackets- the 2" diameter style with pressed-in cups.

Thank you for your replies.

One thing I didn't know was that I may potentially use a MTB triple
crankset and just pull off the inner ring. And looking, it seems like
I could even get the chainring sizes I'm using, as well (38/48, but
something close would be fine, too).

But now looking again, I can't find anything out there in 180mm for
MTB, either. Anyone know where I could look?

Thanks again,
Erik

It's a similar situation to the road cranks. Generally they're
better-quality MTB cranks- Shimano Deore XT grade and above. Since
110mm bolt circle hasn't been made by Shimano for a while, used (Ebay
and such) is one choice, while TA is another possibility.

If this were 20 years ago, I'd point you at Sugino Mighty Tour cranks:
180mm length, 110mm bolt circle, light and strong.

I've got a couple sets of Deore XT 180mm cranks in my collection- but
I'm keeping them. I have plans for them.
