before i decided on and got my jamis trail xr (with no regrets) i saw several 'cheap' (box store i.e. walmart) mountain bikes in the junior category (24") that were 1x7's with no front derailleur but instead a dual chain tensioner in its place... it seemed such an elegant design that i can't get it out of my head now many months later.
what would be involved with ridding a bike of its FD and going to a 1x7? so many accessories, and weight, and complications, would be lost in favor of simplicity... front derailleur, two chainrings, left shifter, shifter cable, etc. and then i'd only have to worry about keeping the rear derailleur in top working order.
(and i'd probably ditch the front brake, too. so on the handlebars i'd have just the brake lever for the rear v-brake which provides Plenty of stopping power as-is, on the left, and the shifter for the RD on the right.)
anyone familiar with the blackspire stinger or dwr chain reactor? both are chain tensioners that mount to the drive side of the bottom bracket.
also, what are my options when it comes to the drive side crank & spider? ideally i'd like to upgrade the 42t outer chainring of the triple set to just a single chainring, 44t (more gear-inches).
ideas? advice? links? any and all information would be awesome.
