    Idea! 400 Ds

    Hi everybody ,
    My girlfriend and I will be getting our 400 DS's on Thursday and will be dropping them off at Performance Bike in Santa Monica CA to have them tuned up ... I hear that although the frames are good, there are certain components that are weak. What parts do you suggest we replace right away. She is 5'6" 105 lbs. and I am 6'3" 220 lbs we will not be doing any hard core ridding. We are going to ride mainly in town and on bike trails. I am concerned that my weight not brake anything and I would like my girlfriend to upgrade for endurance of the parts and for making her bike lighter.Thanks in advance.

    Cheers J.T. & Tania

    You'll probably want to swap in a 500lb spring for her and a 600lb for you on the rear. Aside from that, considering your intended usage, why would you want to dump a lot of cash for minimal weight losses? The bikes should be plenty durable as is for around town type riding. If you don't like the way it shifts or brakes, only then would I consider dropping dough on higher end components. Rather, upgrade to better stuff when things wear out. IMO, if you were to drop a lot of cash on higher end parts now, you would have been better served to buy a higher end bike to begin with. Just go enjoy the bike as is.
    When I'm not windsurfing, I'm mountain biking

    Thank you for your reply. We appreciate your thoughts on this.You have reassured us that the parts aren't that bad and It makes total sense to wait for them to wear out before upgrading.

    I totally agree with stark, the parts are good enough for casual riding. I do have rear shock spring dimensions if you want to swap them out. Just let me know. I'm weigh 195 and a 500lb spring is perfect, maybe a 550lb would be better for me but the 500lb does the job ( KS shock has rebound / lockout selector) . For your G-friend I would go lower, maybe a 350-400lb. As stark recommended a 600 sounds right for your weight.

    Thanks Dice
    It would be great if you could give me the rear shock spring dimensions ..... So a 350lb for Tania and 600lb for me... any place that I should look for the springs?

    Cheers J.T.

    Okay, The dimensions are 3.75 in. long x 1.25 inside diameter x 1.875 outside diameter. I ended up getting one on ebay but it was just a tad bit bigger on the I.D. and O.D.....So I looked around and found a Fox spring here http://webmountainbike.stores.yahoo....ilsprings.html when you order your spring just type in pounds x travel (600 x 1.5) what you get is a Fox Coil Spring 3.5 in long x 1.25 x 1.875 which is way better. It takes around 1 week and a half to get it. Just tell him you want the same as order " webmountainbike-5467 ".

    I agree. Swap the shock in the rear out and be done with it.
