Takes the sting out of the tail.
I fitted this to a steel framed touring bike and now have it dialed in to my liking. Fitting and adjusting could not be easier. It is well made and operates silently and unobtrusively. Experimenting with different spring rates and preload adjustments is very simple. A well made product! I’m very pleased with this buy.

So worth the investment
Im coming from a full-suspension mountain bike history and this combined with the redshift 30 degree stem, gets me really close to that full suspension feeling again. Plus- being a bit older, my spine appreciates the ability to dial in the preload.
