    Shimano Square Taper BB UN72,73,74?

    Where's the best place to pick up one of these? it seems like only the cheaper UN52-54 series is readily available these days.

    nashbar has the UN73 in many sizes for $19.99. use code TKY58 for 10% off. good deal. for some reason it's not in their selection of bottom brackets from the pull down menu but i found it while doing a search for bottom brackets on qbike.com and clicked on the direct link.

    Thanks for all the great tips. I ordered two 68mmx110mm UN73's from Nashbar.
    Almost seems to good to be true at $20 each when they are so hard to find elsewhere.

    Nashbar has a good selection right now. Use Jun85 for 20% today. Great bottom bracket IMO.

    I see these have gone up to $25 from $20 a few weeks ago, still not a bad price. I just received two UN73's from Nashbar. In comparing the UN73 to the older UN72, Shimano has integrated the threaded drive side cup into the steel body. The UN72 uses an aluminum drive side cup which makes it noticeably lighter.

    I noticed the integrated drive side cup on the UN52&53's but not on the UN73. I checked my supply and they are all UN72's. I'll see what arrives. It's for my daughters bike. I'm chucking the boat anchor crankset and bb on her Trek 3700. Thanks..

    Even with the integrated drive side cup, it still came in at 250 grams. Pretty much the same as the Un72's I have......Just checked them both and the 72 was about 240 grams and the 73 about 250 grams.

    Not to beat a dead horse, but with current 15% off code (4TH15), the UN73 is only $17 through the 4th. http://www.nashbar.com/profile.cfm?c...n%20Components
