    Wonder how the Ripley compares with a 140 fork. The geometry is very close to 429c with the longer fork, head angles etc. Cant decide between the 2.

    Run a 140 on the Riplet like the 429 has and it solves all the isses with that kind of riding. The ripley with a 140 is awesome.

    Thanks for the post, I ordered a med Ripley a few weeks ago. I had a Mojo for 5 years and currently ride a Superfly 100 pro. Anyway, I assume you rode the 120 based on the head angle in the article. I went with the 140 shock with the 34, that will slacked it out t about 68.5 which should help with the descending and hopefully keep most of the uphill ability.

    PS I am also hoping that some “real” tires will help it out a bit also, something a bit fatter and more aggressive, especially for around this area. Seems a bit of an odd spec to me but it’s perhaps to save weight or target more xc race riding.

    I had the exact Opposite experience. I ride 429c at dirt demo in Vegas. Hands down fastest bike I had ridden. Easily pedaled out but was harsh on the descent. I rode the Ripley this weekend at sea otter (admittedly I was tired form riding all day) at the bike worked better downhill. The 32 for was overwhelmed however. Input more air in fork and the stout rear end of the Ripley just crushed that Lil 32. Maybe it’s the fox mid stroke issue they are fixing. All told I had the exact opposite experience.

    As a Mojo rider I’ve been eagerly awaiting the release of Ibis’ Ripley, and now that it is out, also for reviews.
    I enjoyed your illuminating comparison with Pivot’s Mach 429, but I am puzzled by the term “latency” when referring to the Ripley’s performance on drops, jumps and technical sections …can you explain what it means in this context, please?

    Best regards,
    Joe.

    Seems like the ticket would be to use a Talas fork so you can ascend at 110MM and descend at 140MM. Would this affect a steeper headangle for climbing and a slacker one for descending for the best of both worlds? Or is my logic flawed?

    Really good way to distinguish two seemingly similar bikes. Nice juxtaposition on wheelbase and head tube length. Great review.

  9. Joe Woollaston

    Oh, I think I get it now, Paul …by latency you mean the suspension is fractionally “late” to respond?
    I was puzzled because the word already exists, but with quite a different meaning to that.

    Best regards,
    Joe.

    So I have had the Ripley for a few weeks went with XT build size medium and specialized roval control carbon wheels, oh yeah its a 140/34 up front with some 2.3 ground control and purgatory tires. It took a few rides to get everything dialed.

    In a word, epic. Just slack enough, smooth, playful, and climbs like mad. The wheels and fork make it a do everything xc/trail charger. Full reviews posted on mtbr. It’s a worthy bike.

    I’ve been looking at both these bikes so I really appreciate the review. But in looking closely at the frame specs, I’m wondering if the experience you had isn’t also related to the fact that you say you rode both bikes in size Large, but in terms of the recommended height (of person), top tube length and wheel base, the 429 carbon Large is more equivalent to a Ripley XL, not a Large.

    Rec Height Medium 429C=5’9″-6’1″
    Rec Height Large Ripley=5’9″-6’2″
    Rec Height XL Ripley=6′-6’6″
    Rec Height Large 429C=6’1″-6’4″

    Medium 429C TT=24″
    Large Ripley TT= 23.8″
    XL Ripley TT=24.6″
    Large 429C TT=24.75″

    Medium 429C WB=44.17″
    Large Ripley WB=44.1″
    XL Ripley WB=44.9″
    Large 429C WB=44.96″

    Obviously there are other important measurements you mention, like head/seat tube angle and front end height, but seems like the Ripley runs small, which would explain in part why it felt better going up and worse going down. Wondering what you would have thought of the Ripley in an XL or the 429C in a medium. Thoughts?

  12. Noah

    Curious your size (6′?) and which size frame of the 429 you rode and your impressions on how it fit you? I know Pivot recommends people put 6’1″ ride a M…. can’t get my head around that.

  13. Simon

    Did somene test the pivot with fox 140 34?
