I have ridden Lon Las Cymru (south to north) on a bike with SA drum brakes without problem. Certainly no overheating or squealing.rotavator wrote: ↑19 Sep 2021, 9:37am How do drum brakes perform on long descents with a load on board e.g. on the long descents on Lon Las Cymru? Are they any better or worse than rim brakes or hydraulic disc brakes or are cable operated disc brakes the best option? I would imagine that drum brakes get very hot and start burning any grease or oil that is near them but do they also fade or squeal?
I have subsequently ridden on my LHT with cantilevers. Again no problems, either with stopping or overheating. The braking was a bit better with cantis than with drums.
In each case I was carrying camping gear. However I am around 63kg, so even with the weight of my luggage I am not a demanding load on the brakes!
