Resurrected the old steel HT over the W/E and thought I'd have a go at this ere 1 X 9 malarky.
I removed the granny and outer rings on the triple chainset and fitted a Gamut P20 dual BB mount jobbie.
Commute in this morning confirmed very quickly that the lack of front mech and/or top retaining guide is a sure fire way to drop the chain at what seemed like every possible opportunity; - leaves on the road, clouds scudding by, you name it
If I stay with 1 X 9, what's going to be the best bet to keep the firkin chain on? I haven't been able to locate anyone who has Gamut's single boomerang BB mount wotsit in stock so should I try an e.13 mount or something like Hope's chain guide?
