Tell me more YukonBoy, I've got Marathon+ on my Brommie and am sort of tempted to spend half a day removing/ refitting the rear wheel so that it's not so daunting.
Any hints / tips / gotchas?
Undo the gear cable via the barrel / lock nut. Then turn to remove it from wheel.
Undo the gear nut, same size spanner needed as other wheel nuts
Then remove chain tensioner
This reveal a normal nut that sits under the chain tensioner.
Undo wheel nuts, there are retaining clips like on front wheel so wiggle these to drop out wheel.
Reverse to refit. Do not try and fit chain tensioner before wheel back in place. Fit wheel, do up inner bolts and ensure retaining clips in place.
Fit chain tensioner with long arm pointing back and shorter arm forward. Engage teeth of jockey wheel of front tensioner with chain. Easier to do if you release rear triangle as if folding.
Fit and tighten up gear cable nut
Fit gear cable and attach to barrel adjuster. Do up lock nut on gear cable.
Swing long arm from back to tension the chain.
Pump up tyre.
Ride, and adjust gears through barrel adjuster as necessary.
