On-One lock on grips, less than a fiver!…limited colours but just go for black anyway, lasted over a year so far.
Wellgo V8 copies, an eBay buy, cheap as you like but still on the bike 12 months later with no noise, play etc
Deore brakes, cheap and excellent, the latest M615s on my bike even have a nice progressive build up to their maximum power, no grabbiness.
Anything bars, seatpost related by FUNN, usually cheap from CRC and excellently made, strong, look good (just about every colour you can think of).
2014 Revelations, pumped them up to the pressure recommended on the fork leg….came over all sceptical as i’m a bit of a luddite preferring a coil spring set-up….went for a ride, superb small bump compliance ramping up nicely for the bigger stuff and using all but the last 5-10mm of travel without bottoming out….changed my perception of air forks after some Fox items left me a bit disillusioned by the concept.
Maxxis tyres, lovely soft grippy compounds in just about every tread configuration you could want/need…usually cheap too.
