'91 Stumpjumper Time Warp Classic....

[DHart]

Take it to your local bike shop if you have one nearby…. A little service and check over won’t do it any harm and will give you piece of mind and trouble free riding for the future especially if you intend to ride it regularly again .

@abr303 ....

Can you tell me what the cassette sizes are on the '91 Stumpjumper? Low gear and high gear?

Forgot to ask... also, what is the wheel size specification (width)?

Can a tire narrower than the stock 1.95" tire (more of a gravel tire width, perhaps 1.5"?) be run on these rims?

I'm just thinking about possibly using this for sort of a hybrid-style riding? Mix of paved, gravel, and easy trails.

Have you looked at this? RB has an amazing archive:

Hope it’s the right one. Writing this with cold hands walking the dog! Specs should be in the back of the catalogue
