Great for vintage bikes
I've a little garage in NYC where we refurbish and modify old vintage bikes, mostly from the 70's and Bel Ray is probably one of the best brand for product range and also for the range of Mineral Oils, which I prefer VS synthetics, for old bikes!<br />www.electricsundays.nyc
