So .. Finally got to ride my bike after all this rain we have had so I better review the Tekin tune I had done after I originally asked the question
I'll start with the negatives ................................................. there aren't any, full stop.
The Customer service was amazing even from a different state and first time customer of TeKin's I was kept well informed at every stage of the rebuild from Ken receiving the shock, rebuilding it and sending it back.
The Turn around time, again amazing, less than a week including posting both ways, Im sure Im not the only shock Ken did that week either.
Ok the important bit the ride, now Im not a racer, infact I have no interest in going fast, Im a Sunday DHer a guy in his almost 30's who likes riding bikes cause it gets him out of the house on the weekends ... that was until this weekend. I was riding at a new (for me) DH track on Sydney's nth shore with a beautiful little rock garden about 3/4's the way down with a little rock stepdown then 2 switchbacks, I spent a good hour sessioning this section trying to get faster and faster, all I could do was giggle, Kens tuning as turned my bike into a weapon. its SUPER stable under foot over the rock section, I feel like I have more contact with the ground when I need it, yet the ability to get the wheels off the ground more and skip whole sections cause I know then bike will be under me when I need it again. As for the drop/stepdown i didn't even notice it was there and the 2 switchbacks were like rails.
To be honest I never thought I bike could feel so good, and with me off to whistler in a month I couldn't be happier
So I guess at the end of this I too will join the group of people in this thread who know what its like to have a Tekin tuned shock/fork and will recommend them to anyone who will listen.
