    Still wondering what BB interface? Square, ISIS?

    Nice that they offer lengths and a BCD that can accept mountain rings. Kind of spendy though.

    For that price I'd just get the shorten double from SRAM S600 MTB crankarms Shortened

    I have a set on my son's Marin. Very happy with them.

    I got a set of shortened Truvativ 5D's. Just wondering about the one above. I live in the same town as Bikesmith and he's done two pairs of cranks for me. Great work, works great.

    But I'm a freak, I like bikes, and those look cool.

    I'd run the 5 bolt version of that. They do look sweet.
    From the photo it looks like they are for Profile spindles(?)

    AC Mini's are about $50, look not quite as cool, but still pretty sweet.

    130mm BCD is common road bike standard but can only accomidate a 38t smallest ring.

    Most all BMX 5-bolt cranks are 110mm BCD, take of minimum ring size of 33t (rare), 34T more commonly available. MTB cranks mostly quit using 110mm BCD around 20+ years ago, went to 94mm BCD as a 5-bolt standard in order to get down to 29t (rare) 30t (common) small size and then later most MTB switched to 104mm 4-bolt which gets you a 32t.

    You can get Mini AC LE's for half the price or just use Sinz. You'll save a little bit of weight going with the AC's vs Sinz. Also look at the Sinz Titanium BB for decent weight savings.
