I had the one from here http://www.bigmassive.co.uk/
A bit more that the Forca one but as far as I can tell pretty similar. I think they are both modeled on the GD classic.
Basically it is a well made bit of kit and does the job. Personally, and this could well just be me… I found it a bit awkward to use.
You have to apply a little bum weight to the saddle to hit the remote then you can push it down. When you want it to pop up you again apply said bum weight and stand quickly to allow it to come up and click into position.
I just found that difficult to do very quickly. I used it on local rides in Yorkshire then round trail centers in Scotland. Locally it was fine but round the trail centers where the terrain changes very quickly I didn’t think it was a fast enough system. User error?! Maybe.
I got a good deal on a GD turbo, which does not need any (pre release) weight when you want the post to go up or down. I find it a great system, much easier and I find it much faster to use on the ride.
I should mention I had tried a friends Reverb before moving to the GD. It just worked and worked fast..thats what I was after in a post. Not available in 27.2 so the GD T was my best bet. X fusion do one but the hit and miss reviews put me off.
I have come to think that spending more is a bit of a sting but worth it in the end.
EDIT: one thing I do like about these cable remotes is the fact you can look after it yourself. Simple construction and spares available. Part of the reason I chose the GD.
