Mrs Julian has just acquired us an oldish minoura turbo with magnets in it.
Basically the magnetic resistance adjust thingy doesn't really make much if any noticeable difference to the resistance.
Didn't have any instructions but schematic and instructions i found on minoura website for a very similar more recent model would suggest it is has all the bits it's supposed to in all the right places, and I have adjusted the cable remote properly. The outboard magnet mount turns smoothly with each click of the adjuster, and the magnets clearly have quite some magnetism in them with a quick looksee with a metal object. One thing i would say is i thought the magnets are supposed to go closer together for increasing resistance. As far as i can tell, all the outboard magnet mount does is rotate when you adjust it -I expected it to move closer or further away from the other magnet as it did so. (like a cable actuated disc brake) The housing etc is all in great condition, in fact barring a little bit of surface corrosion to the main frame, the whole thing looks nearly unused.
1) do the magnets lose their strength after a few years?
2) is the distance they move in and out supposed to be so slight i can't really tell by looking in the top, or is there something up with the gubbins that moves the magnet in and out? (the mount does rotate smoothly as you adjust..)
3) Is the adjustment on magnetic trainers so subtle that my thunder thighs just suck it up without me noticing?
Thanks in advance.
