More problems or should that be challenges

The track wheel recently fitted just arn't quite right. The bearings cant' be adjusted correctly and the front brake is stiff and not pleasing on the eye. So to overcome all of this we will
a) Refit original wheels- easier tyre/tube changes, bearings lovely and 1" diameter bigger to lift pedals up higher for greater cornering clearance
b) 2nd hand front brake requiring the centre bolt to be extended, remove cable hanger and cut front mudguard to clear brake caliper
c) Make chain tensioners to fit rear wheel
d) Refit original seat post new one keeps slidiing down
