    tune cranks

    what do you guys know about them. specifically for SS use. Im only 155lbs, but am going to run a 34-16 gear. so what do you know about the fastfoots and bigfoots? hows the hextaper BB on the fastfoot?

    He's a thread from lst year

    My bigfoot and Philwood square taper has been running fine since then. I weight around 135lbs and if I was going SS I'm probably opt for something a bit stiffer esp if you're going to be standing more often rather than spinning.

    flexy and wide q-factor!

    i had some Bigfoots myself years ago but those are really flexy and worst of all the q-factor is pretty bad using Tune cranks as well. i would really recommend you get some other cranks such as Race face Next LP which are about the same weight but MUCH stiffer.

    by the way: i'm also 150 lbs.

    and if ever: don't get the sixpack verison as there you are stuck with their proprietary BB and will have a hard time to get replacement if needed...

    Race Face sucks mainly because they stopped making those cranks in square taper. I have a few sets and they really are one of the better cranks you can run. For a bit more current versions I have been running the Deus. still in my opinion not as nice as the old LP.

    BTW I do like the tune cranks, just would never consider running any of their parts as I know I would break them in a hurry.

    square vs ISIS

    i also highly recommend square over anything else (including the newest generation of outboard bearings)

    i was lucky to get some nice square LPs for my BMX cruiser

    I still have my LPs from 1999; not the carbons, just the normal aluminum ones. I've beaten the sh!t out of them and they still work like new, and almost look new. I think I'll take them and the Race Face Ti square-taper BB I have them bolted to to the grave.

    I've had these since I could get em....seemed like the wait from conception to availability was at least 2-3 years. I burned throught the first set of rings, but these are still some of my all time favorite cranks.

    P.S. sorry for the mooschy stuff thats me getting married to my girl 3 weeks ago, that wasn't really meant to be in the photo.

    I ran the tune bigfoot on an RF ti bb in 2x9 form, and found them to be uber flexy when sprinting. Derailler rub was a constant problem, not to mention the crankarm would actually interfere with the front derailler (XTR 952).

    I switched to RF Next LP's and havent looked back.

    However if you are still interested, shoot me a PM, i am willing to offload mine.
    Some great sets for the trainer:

    Just wondering why you all seem to prefer the square taper bottom bracket to the isis/octalink/intagrated bb.

    Thanks!

    the isis standard has some problem with durablelity becouse of that the axle has so big diameter and the bearings gets so thin (small balls = weaker).

    octalinc was/is good, the problem is that there isn+t so many crankset out there that has octalinc.

    intregrated ar good, but the limitation with that is the chainline, offen you can get better chainline with a ordinary bottombracket

    I've got 2 sets of those Race Face LP's (one Square and one ISIS). Any suggestions on how to outfit them with light rings in triple (and or double)? Both have stock Race Face 22-32-44 rings and bolts.

    ANY rings are lighter...

    RF have the heaviest rings out there!

    so just about ANY ring will be lighter than the stock Race face rings! I highly recommend Sugino supershifter rings as those shift great, don't cost much and are still lightest rings with a lot of tuning potential left. these days rare to find but occasionally pop up on ebay (and i have some left as well...)

    42t: 65g (can be tuned to sub 50g!)
    32t: 32g
    20t: stock Sugino is steel and ca. 40g so look for a aluminium granny (ca. 18g)

    pictured below a RF Next LP outfitted with tuned Suginos and on the other pic with a KCNC scandium ISIS BB.

    Thanks, Nino. I'll start the search and hunt process.

    With the thick ISIS axle, double row bearings (preferably on both sides) counter the reduced ball size problem. Also, overbuilt seals are always welcome in an MTB BB.

    I agree with Nino on the weight of the Race Face rings. Here are what mine come in at:

    46t = 112g
    32t = 57g
    20t = 30g

    The 20t is a steel ring if I recall right. Of course, the same ring has lasted me for 9 years now, so I won't complain (okay, 4 of those years I ran w/o a granny, so really 5 years of use).

    Yeah, I run a 46-20 split and the XTR front derailler shifts just fine.

    i dont like how your bearings go bad after i mud puddle, the seals are terrible on outboards.

    one advantage of old square taper design is a very low Q factor.
