    Lefty MAX on Rush

    I always found the standard Rush geometry a little nose down for my liking. I loved the way the bike went up hill, but found it a bit nervous downhill.
    I also never got on too well with the damping in the DLR2 lefty - even playing with the oil weights and shim stacks, I couldn't get the bump performance I wanted without excessive bob.

    I noticed that quite a few of the 2008 Rush models in Europe have 'standard' 120mm forks, which have an axel to crown hight of around 500mm (compared to the DLR2's 480mm).

    So, I replaced the DLR2 with a MAX SPV (I have some Manitou Minutes with SPV and like it). I reduced the travel down to 130mm with a 10mm spacer, giving a 500mm axel to crown height (the 130mm travel also matches better the 120mm I have out back since changing for a 190x50mm RP3).


    Well, as you might guess, the bike is not quite so good on steep uphill - the front end wanders a bit more and traction is not so good and you need to keep your weight a litttle further forward to keep the front down.
    But, wow! The bike is so much better downhill: much more stable, better weight distribution, easier to manual. And, the fork damper works properly, absorbing big rocks without wallowing around. Sweet!

    I bet it is Sweet! It probably rides something like a Prophet in between the XC and FR mode, but with slighlty less travel and a little lower to the groung for better cornering.

    I hope you enjoy it.....

    Post a pic if you get a chance.

    That fork will void the lifetime warranty, but if you don't care I'm ok with it.

    I'm sure all of us Uber V riders have voided ours too, but none of us seem to care.

    Well, if the frame can take a 200lb rider with the normal fork, then I'm sure it can take a 150lb rider with a 200mm longer fork.

    It should work fine, I see that Cannondale allows maximum of 500mm axle to crown on the Rush so why not!
    Glad you like it, I considered putting a 650B just onto the front of the Rush to make a similar change just for technical rides and downhill, I managed to get my Lefty work perfectly for me, but it takes some playing around and it sounds like you prefer a lower spring rate with more low speed compression which is hard to get on the DLR.
