Being who he is
There's a few old results on the net suggesting a HD may work for our orange ball bearings. Are you on the KMBC bookface group it may be worth asking there. Actually I'll do it as I need some tyres for my HT build and will mainly be riding up in the Perth hills.Schwalbe tyres (NN, MM, HD etc) in various sizes for 50 bucks at TBE. Not great descriptions on which versions though..
Recommend me a combo to try on pea gravel..
