Hi Guys,

Help me out here......

I will be racing in some XC races, but also for longer training rides in the likes of Lee Quarry.

Currently got SID 110's on my Whippet, but they're getting a bit worn so after some new forks.

My strength seems to be on the flats and uphill and I'm still a bit nervous and slower than others on the rough downs.

Would 120's suit me better and give me more confidence / aid with the downs, or will they reduce my effectiveness going hard on the flat and ups.

Thinking of 120's REBAS or SIDS if some come up cheap.

Thanks,

Pat.

    120's will slacken the geometry slightly and give you more travel, but to be honest such a tiny difference wil be unnoticeable, what would help is stiffer forks with better damping (depending on how old your SIDS are and what damper).

    So would the 120's make tough downs easier due to the extra travel ???

    Or is that down to the damper internals ???

    120 Rebas seem really good value at the moment with the new black stantion ones coming in under £300.

    Thanks,

    As I said, 120's will make it marginally easier (we are talking a tiny margin) all else being equal the fork 'quality' and set up will create much bigger margins.

    The biggest margin comes from the rider, you would probably gain more from a coaching course than from new forks.

    Cheers,

    Fortunately I've recognised my weakness (confidence going down hard rocky stuff) and am working on it.

    Forks needed replacing though, so in essence, there's not much in it, as long as they're half decent and setup to suit my riding style?

    Another +1 for Chase Skills, though I still have a mental block on rock gardens!
