I have test ridden both of the bikes as i was unsure. I currently have a 5.5. I wasn’t that impressed with the Tracer it has to be said, I can’t put my finger on it exactly, it just didn’t feel right. Not sure its an improvement on the 5.5.
On the other hand i was impressed with the Turner, it certainly is a step on in terms of ride and performance from my 5.5.
I ordered a Turner, from my LBS and it will be here in the next week or so. (I had to pick the colour and size that wasn’t in stock)
