Okay, so after initial dumb question the post is now fitted and happily goes up and down as it should reaching the full 170mm extension. This is my first non Reverb post and, although, as others have said the lever feels a bit underwhelming, first impressions are very good. The build quality on the post itself is great, with no left to right play in the saddle, it comes with a two year warranty and I only paid £99.00 for it at Start Fitness (with code EXTRA10 for 10% off). For a budget build it’s spot on.
