@RestlessNative I've not had that problem at all, so you may just have been unlucky...
Uppy downy seatposts: is there one worth me buying yet?
Ah now to be fair... I just bought a new inner post for my gravity dropper, with the 2 inch multi drop- they're not expensive and they come with new shims fitted so I thought why not? Fitted it, and it had absolutely tons of play- it turned out the shims were fitted wrongly. They offered to take it back and fix it, but I got them to send new shims instead rather than post it back to the states, but if they can screw it up in a seperate inner post they can certainly screw it up in a whole post.
So... Gravity Droppers do work but there's space there for them to not work. But they're good at sorting it should it happen.
Gravity dropper turbo multis on both my bikes, mainly due to reliability and service should things go wrong. You can adjust out most of the play with the lockring at the top of the outer post, but I think there will always be a bit of play. The play really doesn't bother me one bit.
GDs are great.
we've got the 27.2 pure post in stock, if OP (or anyone!) is interested....
mines gone back to wiggle so will see what they say
i think the 27.2 pure post actually looks worse than a GD!
"Its worth noting that most remote cables on seatposts form a U bend. So once the water gets in it can't get"
"I have a feeling that the remote cable's, whilst nice, do add to the problems"
You need to a middleburn cable oiler or two into the cable, if it gets sticky you sI have a feeling that the remote cable's, whilst nice, do add to the problemsimply push the dirt back out with WD40/GT85 etc. Plus if you position them along the cable outer just right, then the rubber O-ring on them acts can help stop cable rub too
I went for a KS i900R as I wanted to be able to set it anywhere along its height (not just set drop points decided by the manufacturer), and as I was after a dropper post to increase the amount of saddle drop on my frame (around 80mm drop) where the shock interupts the seattube I wanted more than 4" of drop to partially warrant the outlay
There is quite a lot of play in it now, though as above you don't notice it whilst riding and if anything must help when the bike pings its way through rocks seated climbing or moving weight into corners
The 'patented no slop' guides inside are worn
Theres some quite deep scratching in the inner shaft too and probably connected there is some play fore-aft (ie when you sit on it, it must move) though again its not noticable when riding and still works fine
The older lever on i900Rs although a bit easier to use (when positioned below the bar rather than above)I reckon than the new style was a bit flimsy, I broke 2
The new style ODI lock ring compatible one is a bit pointless though as if you were to mount it on the inner edge of your grip replacing a grip lock ring then you have reposition your whole hand to use the lever which is effectively much further back. I've got mine inboard of the brake and shifter though because its ODI lock ring compatible you need to have something under the clamp (I've got the 'clip' ends of an old locking grip middle sawn off) else it will score your bars as its only clamping around half of the way round the bar
Servicing its pretty simple, basically remove the lower nut and threaded cap, degrease/clean out and bung suspension grease back in
Probably the worst thing about i900's though is the (single bolt) clamp. To get it tight enough so the saddle won't move I need a ball ended style (6mm) allen key with an extension. More of a problem though are the notches in 'splines' of the clamp which means that my saddle has to point slightly too back (freeride) or slightly too forward (uphill). I could get it pretty much flat with my last saddle though I think it had slightly bent rails
i950's look like they have similar 'splined' type notches to grip with too
I have put down a deposit for an i7 and remote kit. Shim ordered from CR.
We'll see how it works out....?
KS850 27.2 with a shim? Heavy, only about £55 and works. Its a seatpost. You don't need these things all the time surely?
Well, my i7+remote kit arrived from the nice peeps at 18bikes today (cheers chaps),,the remote lever went together easy enough and set to the inside coller on the lockon grip feels easy to use and tucked away from damage, it's nice and smooth going up and down with no play at all, it's getting sloppy round here now so I'll see how the seals hold up
i7 with (orange to match bike!) remote kit fitted in time for trip to Spain. We'll see how it fairs.....
This looks ok hopefully cheaper than the Rock shox post
