Not to sidetrack this excellent sidetrack even further (from the Who calls themselves a Wah or Suff?) but I’m all in for the KICKR BIKE vs the CLIMB for different reasons.
I specifically wanted an INDOOR BIKE that did NOT require me to use the frame, wheels, tires, chains, cranks, etc that I ride outside. I simply don’t want all that mess inside, and I ABSOLUTELY don’t want to have to fiddle with putting it in or out of a trainer, and I don’t want the expense of buying another bike AND trainer to pair them up for indoor rides.
So that KEPT ME FROM even trying any apps like SYSTM or that crap Z app (just my opinion) for as long as it took for me to finally decide I could benefit from SOME indoor training (and could stand being cooped, since I would mainly do it when outside wasn’t so doable or desirable.)
Thus the KICKR BIKE, V1, plus SYSTM became reality for me in January of 2022.
Never regretted the purchase yet. Never regretted that some free subscription to SYSTM also came with it.
Glad I didn’t have to put my expensive bike into a trainer frame and subject it to the stresses that it was not designed to face. Glad I’ve had the freedom to switch to doing indoor or outdoor rides on any given day without having to change the bike from one to the other. All good things, at least for me.
ONE OTHER VERY NICE BENEFIT of a KICKR BIKE that became a really helpful thing to me is the OPPORTUNITY TO TRY DIFFERENT LENGTH CRANKS FOR FREE!
Yes, I made the change to the 165mm length about 6 months ago on my KICKR BIKE to see what I learned compared to the 172.5mm Stages Shimano Ultegra crankset on my DOMANE SLR frame.
I continue to ride both sizes, 165 indoor, 172.5 outdoor, and have very clearly noticed that I am always more comfortable on the KICKR Bike than I am on the DOMANE.
In fact, it was only this option that let me become firmly convinced that for me, 165mm is the max I will ever buy again, at least for a road OR gravel bike. (The ignorant and SLOW bike industry is STILL stupidly set on pushing cranks that are TOO LONG for riders, so you find that shorter cranks are only BEGINNING to be spec’d or offered on some road frames but on gravel frames, they still pretty much stop at 170mm for the short end. It’s quite ludicrous, frankly.)
So I’ve been testing the waters using the KICKR BIKE, and I clearly benefit from having a less closed hip angle. At the very least, in comfort, but also possibly in endurance and maybe even in power, though that’s less convincing.
There is a LOT to be said for a 5-position crankarm on an indoor bike to let you experiment and try things out without having to beg, borrow, or buy (or steal?) different sized cranks.
I only wish it went even further, and let me try 160mm because that is very likely where I will land when I finally decide what power meter crankset (or groupset) to put on my DOMANE, (which finally on today’s 100-mile ride decided to stop shifting down to the small ring when I was out about 40 miles from home… Grr… But I figured out how to manually push the little metal part back into place under the shifter lever to reset it so it would then make the shift. Had to do that over and over every time I rotated from big to little ring on a very hilly course. It made it very clear that I AM going to have to make this groupset change or only shifters and crankset change very soon!
I’m afraid I’m going to fall into the electronic shifting world, whether I like it or not… But I’m still in a heated internal debate about that choice. I do NOT like any of the options well enough yet to go “all-in” without reservations.
