The best stand to fit on the RC120 Disc is the 500 chainstay stand. www.decathlon.co.uk/p/500-chainstay-stand/_/R-p-12228?mc=8302792 the double stand is likely to foul the front derailleur cable.
@@TheDecathlonMan nope. Why? I've never had good luck with chainstay stands. Too unsteady plus the look silly when folded up as the look like an exhaust pipe 😁.
Mainly the ST range needs a chainstay stand as they have the correct shape chainstays, Riversides and any bikes with a bracket underneath will work with the central stand.
The ST50 is essentially the old 340 frame so either one of our chainstay stands will fit. www.decathlon.co.uk/p/500-chainstay-stand/_/R-p-12228?mc=8302792
