    165mm crank with 46/36/24 rings?

    Can this combination be found or built, considering the BCD restrictions for the granny?

    what you need is a 110/74BCD touring triple, or 104/64BCD MTB triple.
    Food for thought: if you aren't dead by 2050, you and your entire family will be within a few years from starvation. Now that is a cruel gift to leave for your offspring. ;)

    Thanks.
    The 110 BCD should allow my 36 middle ring, and the 74 BCD is good for a 24 granny.
    Now all that I need is find one of those sets!
    It is intended for my vintage Univega Sportour - does it's BB accommodate the Sugino sets?

    or a singleizer , IRD makes one, the middle (34?)ring then bolts the 74 on it.
    so you get a 110 double, arm set,and the 3 rings, as an each.


    does it's BB accommodate the Sugino sets?
    british standard thread is common on Japan/ Asian import bikes.

    I run 45/34/24 on an old Sugino touring crank, 110/74BCD.

    That would do me just fine too I think. Are you as happy with that setup as you expected?
    Where did you get it?

    Through any bike shop with a QBP account.. probably several in medford ashland area.

    or pay shipping from these guys they also have a QBP account,
    note the corner label on the picture ..

    Might have to get different chainrings to your requirements also,
    LBS might give you a Take - Off Credit, for the stock set of chainrings.

    It is 7/8 speed compatible, with a Chain Compatibility: 3/32", but I have a 9-speed cassette and chain, which may be a problem.

    The mtb triple offers much in the way of options as you can run your desired combination quite easily and if you run a tight triple with a very low granny you can also tighten up the rear cassette and still retain some excellent low end gearing.

    Have done this on a number of bikes to get a stump pulling low gear, tight spacing and closer jumps in the rear for very crisp and smooth shifts, and a top end of 100 gear inches.

    Mountain bike components evolved from touring bikes so putting modern mtb parts on a tourer makes great sense as you rarely need the top end of a road bike.

    If it matters [might be less than 0.5mm, You could always just get 3_ 9 speed thickness tooth chainrings . Salsa another QBP brand, TA and Black spire and some other folks
    use 7075 alloy , which is harder wearing than the 6061 stuff stock on the Sugino .. price point

    The Deore LX is a compact 5 bolt triple that uses a 58 mm inner and 94mm outer... it is a nice crank in that you can run a granny as low as 20 teeth but do not think it was offered in a 165 length crank.

    I have one of these I plan to use on some future project and it would be really nice for a half step set up.

    Very happy. The gearing is custom, but I used one of the original chainrings (it came stock as a 50/45/28 half-step style gearing). I spend 80% of my time in the 34, 12% in the 24, and 8% in the 45. I got the crankarm as a replacement for one with corroded granny gear screws from user FBinNY. Now that I think about it, it is actually an SR, not a Sugino.

    I've bought a 165mm 46-36-26 sugino XD600 from velo orange before, but they no longer have that in stock.

    actually, jenson usa has it, but sadly they don't have a 74BCD 24t, which would have saved much hassle.

    The XD 600 is all you need. 110/74 rings rule as far as I'm concerned. Shimano usually plays games with their rings, and you don't find this out until you need a replacement. 110/74 rings are a long standing standard and easy to find.

    There's no issues using a 9 speed chain on the XD 600!! Zero .. none .. nada. You''ll see various websites selling it as 9 speed ... some 7/8 speed ... and it all means nothing!

    Read this too : http://sheldonbrown.com/speeds.html

    Check out the XD-500 too .... same crank arms ... different logo and rings. Nicer looking. Don't worry about the 48. The real life difference vs. a 46 you may not even notice.

    I just finished this last weekend for the 5'3" GF: http://www.dim.com/~ryoder/soma-buena-vista.jpg
    XD-600, 152mm cranks, 50T large ring, 9speed XT parts at the rear, KMC 9s chain, Ultegra FD.
    It shifts great.

    Velo Orange seems to be interested in selling their own brand nowadays (not that I'm objecting). This crank:
    http://store.velo-orange.com/index.p...24x34x48t.html
    would fit the requirements with a chainring change.
