After a recent bike holiday i'm leaning towards the double and bash route on my 'big' bike (Marin Wolf Ridge Quad 140).
What's the best set up for this? Is sticking with the standard 32 middle ring a good idea or should i be looking at a 36 tooth ring?
Do i need to alter the spacing of the chainset so i can use a wider spread of gears etc?
All info gratefully accepted!
