    Are the YT weights accurate (Jeffsy 29er weights)?

    I'm thinking about picking up a new 29er and notice that the Jeffsy 29ers seem quite light for an AM trail bike (29.1 lb for alu, 28.4 lb for CF). Says the bikes may be +/-5% difference.

    Does anyone know the weights out of the box?

    I'm always skeptical of manufacturer weights. Seems like every bike in that category is "30lbs" regardless of build. Some companies base their weights on a small.

    ^ that's what I was thinking too. And I believe YT mentions that the advertised weights are the smalls

    Large 2017 CF1 was 29.6 lbs out of the box with Chester pedals.
    More you beef it up, more it will handle like a cow....:skep:

    My 2017 Jeffsy CF1 Med (27.5) comes in at 30.6lbs by my scale.

    That's set up tubeless with CushCores and RF Atlas pedals.

    My Jeffsy CF Pro 27 in XL is 29 lbs with frame frame protection and heavy pedals and tubeless.
    With a different wheel set
    and tires I could bring it down to 26,5 lbs.

    I don't trust anything but a frame weight on a digital scale... anyone have a pic? Hoping the new Jeffsy will be under 6 lbs w/ shock.

    Thanks,

    Maybe the small will be close to 6lb, but I doubt it will be under.
    Making shit harder than it needs to be isn't awesome, it's just...harder.

    I need to correct something, 29.6 was wfter swapping bar to RF NextR CF bar...

    But... Still not sure how my CF1, Large, 29r is lighter than your Medium, 27.5... Our scales must be from different planets :P
    You have Cush cores though ... I dunno

    I believe my XL CF PRO 29 is around 27.8ish esi grips, chester pedals, and tubeless Continental Mountain king 2018. The e*13 tires had to go, they wore me out, heavy and slow.

    Scales can definitely vary significantly, especially garden variety digital bathroom scales.

    And, looking again at the things I didn't think about, I have:

    mucky nuts front fender
    Magic Mary front tire
    Tubeless
    CushCore
    WTB Volt ChroMo saddle
    ODI Troy Lee lock on grips
    Crank Boots
    OneUp Bash Guide
    Fenix light mount
    RockBros bell

    Individually they don't weigh much at all, but together maybe a pound or two?

    Honestly, I think 1 lbs difference is not noticeable. And I'd rather add few useful accessories, like mud guard etc, than try to save few grams

    Oh, and I got the WTB Volt Pro chromo saddle too. Just got it. My original one wore out, so rails were loose in saddle's plastic. and fabric was starting to wear out too.

    Riding the 2019 Jeffsy CF Pro in size XXL.
    With the E13 TRS+ tires, preinstalled innertubes and my large crankbrother stamp pedals installed, weight came in on 14,5kg (32pounds). Which is fair, but not very light.

    I'm not a big fan of the E13 tires (I guess that they'll be great in a bikepark, but they feel heavy and draggy and I still pedal most of the time uphill too).
    I've replaced them 2,35" Nobby Nics with snake skin protection and made them tubeless.

    With the NN and still having the crackbrothers installed, I now measured 13,6kg (30pounds) - Quite surprised to see such a big difference, especially as it's all rolling weight.

    That is a big difference! So smaller tires with tape and sealant are almost 1kg less. Nice!

    My XL CF Pro is 30.7lbs without pedals. That's with the stock tires and tubes. I'll likely go with Maxxis DHF/DHR2 eventually (maybe before first ride ). Hoping it'll have the same weight drop, 2.2lbs less would make it on par with my Bronson.

    @BunniBoi Which crank boots did you use? Not sure which ones fit.

    They seem to be pretty good with just picking the one that matches the description. But note I have a 2017 27.5 Jeffsy. Not sure what crankset you have.

    Ah, OK. I have the 2019 CF Pro which has SRAM GX cranks.

    I should have realized from the date posted we'd have different builds.
