It turns out the distinctly average Suntour Raidon fork on the Bizango can be easily transformed ☺
From new, the legs are lubed with grease and the forks are noticeably sticky for small bump sensitivity. I read about people cleaning out the grease, adding foam rings below the wiper seals and 15ml of oil in each leg, which sounded like it was a big improvement... without horror stories about long term issues. Being as I've got a packet of Tungsten disulphide powder (WS2), I thought this would be a worthy place for a sprinkle at the same time.
With the lower legs removed, the difference in quality between the Raidon moco /spring units and RS Reba is obvious, but thats hardly surprising considering the price difference.
The lower legs already had foam rings installed, so I just cleaned out the grease and gave the wiper seals, stanchions and as far as possible, the bushes a good rub with the WS2 powder. Plus I mixed a bit of WS2 into 30ml of 5W40 fully synthetic engine oil. With the lowers partially fitted and the fork angled upwards like assembling a Rockshox , 15ml of oil injected into each leg before refitting the retaining bolts (theres not enough thread for a crush washer, so a smear of RTV silicone under the bolt head) and finally working the fork through a few compression cycles.
The difference is huge 😀 infact there's probably less stiction compared the Rebas which are oil lubed and also have TF tuned ultra low friction wiper seals.
