Dropper seat post for Scott Spark 720

When you say 'control under the saddle' do you mean external cable routing or actual handle/lever under the saddle?

KS do half decent "lever under the seats"....

Thanks all - as usual in my dotage did not explain properly Meant to say have been told could not have dropper post with control on bars - only under saddle which I don't think I could cope with as seat down now usually coincides with me hanging on to both grips to avoid or rather delay the inevitable catastrophe So is best idea cheap/ reasonable post and cable ties under top frame to get to bars

That's ridiculous...of course you can?! what you can't have is an internal routed version...i agree with you on the "under-the-saddle" remote...it removes a lot of the benefits.
However, the Spark is more of a XC racing machine...not really dropper orientated...

Don't get me wrong...i had one on my HT which has a similar geometry to the Spark...of course it will help a lot on your riding and for me it is one of those items i will always have.

My XC oriented HT has a dropper - makes a difference!
I've got the KS/exaform eTen linked at the top of the page - really good value.
Yes the bars look a bit crowded, but I put my remote between brake and shifter as I two finger brake which meant I could create a bit of space.

Once you apply a bit of logic to where you want the remote it isn't an issue.

Have you got any cables running along the top tube? if so just cable tie the dropper cable to them.

I'm still not thinking of getting one..but as a matter of interest does anyone know if any dropper post would be compatible with an I-beam saddle ?

Spark may be Xc but is more than capable on the trail dh sections imo. Wouldn't be without my dropper

I've edited my initial comment, but just to clarify, i also believe droppers are useful on all bikes and i actually believe that you don't need more than 120mm travel for the vast majority of trails. I think the Spark is an excellent bike and one that I've considered before. I had a Scott Scale and a Van Nicholas Tuareg, both XC racing orientated, and both had droppers...however i was using the bikes for slightly different use than what they are supposed to be used for...as light as possible bikes to take you from A to B in the fastest time. We all know they geometry is not orientated for big drops, descents, etc.
However, of course a dropper helps any bike and i could not ride without one now because I'm sure it saved me from falling in some instances.

Cbm, on a recent thread here regarding droppers we came to the conclusions:
- droppers are great and change your riding for the better...when you try you will never go back
- they can be quite problematic, and can be unreliable...they are a bit hit-and-miss...some droppers last years without problems, but others of the same brand can be a pain
- cable operated are usually the most reliable
- RockShox Reverbs are usually seen as the most problematic...but i also think its because they are the most common ones...however they have an excellent warranty and replacement policy and quick turn-around...require bleeding from time to time
- Gravity post seems to be the most reliable...but has a face only a mother could love...Thomson and KS Lev have good reputation but are pricey.

That's what I meant! You tend to hear a lot of problems with Reverbs, but I think it's because they have sold a lot more than other brands, specially because they come standard on loads of bikes, unlike others!
