I’ve recently (8 weeks ago)got a Kettler speed pro & it’s great.
Silent, exceedingly rigid & the ability to offer a brutal workout as easily as a relaxed stretch of the legs.
I had (have) a Tacx Suntori in the garage with my road bike on but it’s been barely used. Last winter I actually preferred to go out in the dark & wet (with help from my Troutlight) rather than train in the dry.
Now with the spinning bike I definitely choose to use this. To be fair one of the big differences is that the spinner is in the house instead of the garage. This is down to the size, perceived cleanliness & comparative silent running.
My lady also uses the spinning bike (to coincide with watching Eastenders 🙂 ) so it’s very easy to change seating position.
