I'm not massively up to speed with this stuff as I just ride my bike these days rather than trawling the net for the latests fads but as a 1x9 user, these caught my eye.
Got questions though!
- Are they 1x10 only (assuming a 10 speed chain is narrower than a 9 speed one)? Planning on going 10 speed shortly anyway as there is limited life left in my chain/cassette.
- Do they completely remove the need for a chain guide of any description? Bike is a Five which gets chucked down all manner of rocky stuff so I do like the security of a chain guide but if I'm lugging around extra weight for nowt then I'd rather lose it.
