Endura zyme 3/4 shorts, good fit – cheap, tough as old boots and keep my knees pretty well protected.
Specialized 2-bliss tyres – Good price, nice tread patterns, good weight, dual compound and tubeless ready.
Merlin built wheels – good price, well made and good service.
Truvativ holzfella stem – ugly, heavy but cheap, incredibly stiff and tough.
Shimano deore disc brake levers – shimano don’t do rebuild kits but at £12.99 a lever who needs them.
Just some off the top of my head.
