    Parting ways with XT ice-tech rotors for lighter HS1 not worth it in this case?

    One bike has XT ice-tech rotors, about 114g each, 160mm. They have been durable, don't pulsate and simply work.

    Other bike has HS1. About 95g (160mm) each and for my xc race needs they are good.

    I've had crappy rotors that pulsated and wore quickly although they were light. Having said that, from a WW perspective, would you buy another set of HS1 (about $11 per set delivered from Hong Kong, reputable seller) and sell the ice-techs (barely used, buddy would give about $60 pair) or would you just toss the HS1 on the raceday bike and use the heavier XT for the other bike?

    160mm HS1 @ 95g is not that light tbbh

    using 86g Formula 160mm 1-piece steel rotors currently instead of 39g to 48g 160mm alloy Innolites that are now reserved for competition. have no grumbles with the Formula rotors - they haven't warped, cool-down rapidly & no chatter or squeal

    weenie rotors mostly work okay when the surfaces are new & pristine, but even then - the lower performance often forces me to brake early & longer, rather than hard & late…

    nabbed a pair of new 160mm steel Formula's on the big auction site the other day, Taiwanese seller, approx $21.30 each inc free postage… they might be a good compromise between the XT & HS1?

    the mrs has some 160mm & 180mm Formula red ano alloy spider + steel rotors arriving from Italy tomorrow, will put them on the scales likely be a tad lighter than XT

    hope that's of some help

    I had hs1 rotors that came stock on my superfly. Nothing but problems with squealing. Tried everything. New pads a couple of times. Proper bed in, bled bled bled, tape trick. Nothing worked. Got some touch but lighter ashima airotors and so far no problems. Quiet with great modulation. So to some it up hs1 were horrible for me. I've heard avid rotors are some of the worst out there.

    Avid's can't be that bad! …have you tried using copper grease between the pads & the caliper pistons?


    79g 160mm Hope Race-Edition X2 floating rotor

    purchased a pair of these Hope Race-Edition floating rotors a while ago, great stopping etc - but don't work well with Formula or Magura calipers + the open design munches brake pads compared to Formula's design

    I've been using g3 clean sweeps with my xt brakes. Works well.

    My HS1's were lighter than 95g and work great with the XO trails, no complaints, and I went from 180mm fr/rr xt to 160 fr/rr HS1, pretty substantial weight drop.
    Hardrock 29er, Niner EMD9, Cannondale F29, Camber Expert, 650b Nickel all gone.

    2013 Formula 160mm 6-bolt blingy rotor arrived/weighed/installed/super/smashing/great


    96.6g -2013 Formula 6-bolt red ano 160mm #2

    the mrs's vapid red anodising fetish still raging - my stealthy black ano old design (circa 2010) 180mm Formula rotors weighed 108 & 109g

    just to compare...

    87.7g 2013 Formula 6-bolt 160mm #1

    ...my choice to replace your XT rotor would be a Shimano XTR SM-RT99
