Dual Ring/ Dual Chainguide
I'm trying to understand is that Dual Ring System like (Gamut P30) actually gives me the option to use both rings with chain tensioner ?
According to the article, that's exactly what it does:
The stepped roller helps maintain tension no matter what ring you’re using
and shifting remains remarkably smooth throughout. We had no issues with dropping the chain, even after throwing some of the nastiest compressions and terrain at it – a good piece of kit.
Great, i had to make sure.
Because i always considered chain-tensioner as single speed.
