How to condition nubuck leather saddle?
 

I've got a 1985 Trek 460 with a very nice condition San Marco Lazer saddle. Here is the catalog with the picture, only mine is now tan color rather than black like the one in the catalog.

At home I have some Obenauf's Saddle goop from Rivendell and some Lexol leather treatment. Would either of those be appropriate for this saddle?

One advice if you want to better the colour, is to carefully apply the wanted colour with shoecream. Rub it in extremely gentle and polish it hard after awhile...as you do with shoes! Spraycolour for shoes may also be an alternative.

I have a Concor suede saddle ca. 1979 that's more like nubuck now. I've used Sno-seal on it, sparingly. Whatever you use, don't use a lot, and don't use anything that could stretch the leather, eg. oil-based products.
