But if AAAC starts the way he did the other night and hits us quite early you are going to want to go after him to stay with him
Got my Pro bits last night and swapped out my PCB and stepper motor. All appears to be working but I am not sure of the real results.
I am on 3.01 FW in the trainer and I am not getting any update prompts, is this the latest Pro firmware?
I don't appear to have FEC but this may because I have a very early ANT+ dongle.
I will have to eat my hat regarding Flywheel distortion. The Pro Flywheel is a whole 1kg lighter than the Classic (1.9 to 2.9 kg) and the flywheel I got with the Pro didn't run true, not sure if its warped or whether the mating surface is not true so I have stuck with the Classic Flywheel. This will mean slower acceleration but more inertia.
The Pro Roller is solid metal where as the Classic is plastic, the Pro Roller spindle has a Woodruf key on the left side where as the Classic has a knurled spindle.
They are still using a permenant thread lock on the nuts which is evident by the damage on the thread of the Pro spindle either that or whoever dismantled it didn't realise the spindle is left hand threaded both ends (which is a bit odd).
As a result I couldn't transpose the Pro Roller into my Classic body as the thread was totally shot so if anyone has a usable spare Prod Spindle I might be interested.
The Pro and Classic Turbo body is identicle other than the nose of the body that goes into the respective frames. I couldn't get the Pro body into the Classic frame so I assume it is slighly wider which is a bit odd. The nose of the Pro body was damaged anyway as the plastic was broken away from the area of the sprung frame attachment bolts which is, IMO, much less sturdy then the Classics nut and bolt. I assume this has been done for speed of attach/detachment for transportability.
The stepper motor, magnets and magnet carrier are identicle other than the Classic uses two solid neodymium magnets but the Pro uses four piggy-backed in pairs. (I assume a manufacture cost reduction exercise)
The Classic uses bi-hex screws whilst the Pro uses Philips the former is a better more durable screw head but the latter is probably cheaper.
I couldn't see much differnece on the PCB's other than the lack of the USB port on the Pro and the addition of a power LED but I didn't look to hard as it is electrickery and I'm not so good at that.
I need to run a few tests to see if everything is running correctly but I did a couple of my short up/down sessions last night and I can confirm that I now accelerate downhill istead of going to Vmax in a flash which means I will loose time there.
My descending watt values vs speed and effort appear a lot more realistic now so my average watts will go down and average as a result.
I get far more inertia going into climbs but I don't get those bazaar torque spikes so again my average watts will go down but I may gain some average speed or I could loose some because I don't get that power spiking.
One other thing I did notice in that on switching on mains my Classic would motor the magnets toward the flywheel and then back which I always assumed was to reset the magnets to a null possition as there is an optical sensor gate on the PCB which is interupted by a tab on the magnet carrier.
The Pro does not appear to do this, do you guys get a sound of the motor running in and out when you switch on?
In summary the transplant was a mechanical succes and everything seams to work but if I don't get FEC I haven't acheived much other than perhaps making my trainer behave like most of yours.
One good bit of news for all those Vortex/KICKR users is that I get blue speed numbers on the down/up slope transition!!!
that leaves a lot of drafting
