MTB (Compact) 386 is a radical new crank design that allows smaller chainring combinations.
386 is a 3 bolt spider, with one bolt hidden. 386 has a 86mm bolt circle dia. and allows 42/27 or 39/27 combinations. The new MTB (Compact) 386 system is closer to triple gearing than any other 2 x 9 gearing options.
The MTB (Compact) 386 system allows a smaller inner chainring, so combinations of 42/27 or 39/27 are possible, which provides a wide range of gearing options, using only two rings. This new crank also increases spider stiffness.
Your chainset must fit onto your bottom bracket! There are currently four chainset/bottom bracket interfaces that you're likely to come across. If your bottom bracket is made by Shimano and it has splines, then you need an Octalink chainset. If your b/b is NOT made by Shimano and it has splines, it's almost certainly ISIS. There are a very few non-Shimano chainsets with Shimano Octalink interfaces so, to be sure, count the splines - ISIS has 9, Octalink has (surprise, surprise) 8. No matter which brand of b/b you have, if it has a square interface, it will require a traditional square taper chainset. If you have one of the new Hollowtech II systems, you will need to choose the exact chainset that matches your bottom bracket. Most MTB chainsets are now 9-speed compatible but these will work with an 8-speed system.
The driving force of bicycle component maker Full Speed Ahead is well captured in their name. FSA stays ahead of the competition through design innovation and manufacturing expertise. FSA's manufacturing base is in Taiwan, but they are truly a global company, with offices in the USA & Italy that collaborate to direct FSA's component development. FSA offers solutions for speed across a broad range of bicycle components; from headsets to wheels; cranksets and bottom brackets, Vision Time Trial & Triathlon bars and handlebars & stems. Why FSA win: Using ceramic, stainless steel, titanium and a half dozen grades of aluminium and numerous composite materials including molded, tubular and high-compression plate carbon fibre gives them the ability to apply the perfect material to each specific application.
