    Rotor size on 2014 Superfly 9.8 SL?

    My current 2012 Superfly 100 AL elite came equipped with 180/160 rotors. Getting mixed info on 2014 SF . Anyone know what the rotors are spec'd at?

    It's on order comes in for test ride Saturday.

    Thanks

    Hmm OK, I was coming back here to post because I just looked at a 9.7 and a 9.8 SL in a 17.5 and they were 160/160

    so not sure why the difference

    Size of bike the Lg and XL have bigger rotors most likely that's my guess

    Trek's Tech Site just shows 160 F&R for all sizes.

    Not sure why it matters much. Rotors are easily up/downsized.

    I'm 210 pounds and run 160/160 on most of my bikes with no overheating issues, and I ride a lot of steep hills.

    I am a little over 180lbs and I use a 203/180, but mostly for looks instead of performance.

    Just because the pic shows it, doesn't mean it's what you'll get. As PauLCa916 said, the L and XL bikes most likely have bigger rotors, but it is very likely that all sizes are spec'd with 160/160. OP just looked at a 17.5 with 160/160...

    I'm OP & just received the 21" 9.8 Superfly SL and it came spec'd with 160/160. Now these are the "ice tech" rotors that are supposed to dissipate heat better and thus not require 180 or 203 for adequate stopping. I've got about 50 miles on and thus far haven't noticed and stopping power issues (they stop just fine) haven't been on them enough to notice if they'll suffer fade from overheating but they are marketed specifically not to do that.

    It might depend on the frame size, I know some manufacturers change various parts based on frame size.

    FWIW, I have a 2013 Superfly 100 (XL) and it has 180/160

    Depends on bike weight too. Maybe the 9.8 SL is light enough to warrant the smaller rotor. I know the alloy models would likely feel better with a 180 up front due to the extra weight.

    Dang. I have the 2014 Fuel EX8 29er with 180/180, and I will be upsizing to 203/203. My '08 Fuel EX9 with Juicy 7's has 180/180, and stops beautifully.
    My Fuel EX8 29er is under-braked with those SLXs and the 180 rotors. I don't blame the brakes themselves, but the rotor size.

    I noticed on a steeper downhill (short) that I had "enough" brakes, but not mind blowing brakes. I wish I could run something larger than a 203, I would!
