When I first started cycling 8 years ago I was amazed at the cost of the little squirt bottles of lube. I then found Castrol's Chain Wax, an aerosol spray at a motorbike shop. My LocalBikeShop said it was thick for a bicycle chain, but that they used it and it worked. I still have the same 400ml can 6 years later, nearly finished, with the price tag still on it- R92.33. I have 5 bikes (use them all 3 road 2 MTB - that's for another rave), and use the Castrol product on them all. At the Argus Expo i came across Giant's Fresh Speed Citrus Chain Wax, for R45. Can anyone expound on the pro's and cons of these 2 products in terms of their experience, especially the Giant, since I have no experience of it?
