    Database for spring weights on Haro X . Bikes

    Hi everyone!

    im starting this thread as a database for anyone needing info on rear shocks weights and respective travel, regarding monopivot haro x series bikes.

    i weight 62 kg ( 136 lbs ) and my haro X2 bike came with an 600 lbs x 2.0 spring on a manitou metel. travel is set up for 6 inches

    Clearly this is not the perfect spring for my weight as the sag is only one fifth of the travel, and it doesnt absorb small bumps. Also i had to use less rebound to avoid being sprung off after harder landings.

    im trying a 450 lbs x 20.0 spring to see if it works properly.

    so far i havent test it on big drops, but right now it seems fine small bumps wise. probably on bigger drops it will bottom out easily...

    so tell us your weight and coil weight, shock, and relevant info...

    thank you,

    Marcolino

    Awesome idea! Thanks Marcolino. I'll check the spring rate of my X7 so it can be added. I'm pretty sure it's a 350; I'm about 130 lbs and the bike is set up for DH, hence I went with a lighter spring rate.

    cool, thanks downhilljill!


    Hopefully everyone will like the idea and also start doing this with other models too...

    thats what i think forums should be, for gathering info and for everyone to benefit from it.

    i hope this spreads like wild fire, eheh!


    Also i forgot to say i usually dont go over 5 feet drops...with proper receptions, not to flat..
    .
    Sometimes theres the street attack and theres this 8 stairs i do, landing in almost flat cement reception. even there the 600 lbs spring goes to the end of the travel.

    probably tomorrow ill try the 450 lbs and have news...

    well, i just went for a night spin, to try the 450 lbs spring.

    it suits me perfectly. i went for a 3.5 feet cement drop. i didnt noticed if it bottomed out, but the landings are smoother. on stairs it feels a bit plusher. Also the riding position is better for my style of riding, slacker... i bet that dowhilling will be perfect with this rate...

    Also i reckon i lost a few gram in the swap!!! yeah!

    happy riding people!

    i went for a real test, street style and freeride stuff.

    i noticed better small bump compliance, but the rear seems to sag too much...

    but on repeated bumps it seems to squat more than id like, stairs, etc...

    i needed to readjust the rebound...

    this rate seems to be a bit less than what i need...probably 500 lbs...

    or could it be the manitou metel that isnt responsive enough???

    what do you people think?

    does anyone had similar problems?

    All doubts vanished! ( at least the ones related with the manitou spring rate )

    1- picked up a ruler

    2- I satted on the bike

    3- measured sag


    Facts:

    450 lbs x 2.0 = 200 mm (eye2eye + - ) on manitou metel R

    Sag (e2e measurement ) = 185 mm

    shaft sag is 15 mm (200-185)...

    shock travel 2 inch = 50,8 mm

    15 mm sag = 30% of 50,8mm travel

    purrfect sag!

    Math is our friend!!!

    Now im happier! i guess i wasnt used to that rear sagging that much.

    I was also using a schwalbe rear tire wich was all dryed up and hard as rocks.
    i also forgot i was running a normal tube.

    I replaced it for my normal rear setup: maxxis highroller 2.5 and continental dh tube.

    fiddled a bit with the rebound button and voil!

    its a go!!!
