First seen as a prototype at Eurobike 2018, and without a name, Saris are now shipping the MP1 Nfinity Trainer Platform for indoor cycling. After a many hours and a few hundred virtual kms, this is my take on the experience of using the MP1 indoors.

• Built-in front wheel block for road and MTB.

Have you tried this with the Kickr Bike?
No. That’s more an expensive party trick than useful information, at this point in time anyway. Maybe one day.
Great review as always! I’ve actually been using one of those side to side rockers with little balloons on each side. What I realized is the bike and trainer together causes an inevitable imbalance of weight towards the left where the flywheel is, and I have to balance that by inflating one balloon more than the other. Is there such a mechanism in the MP1 to address the weight imbalance, or is it a non-issue at all?
