Отзыв о Система JGbike 170 мм для горного велосипеда с квадратным конусом 68-73 BB, звездочкой и болтами 104 BCD для шоссейного велосипеда MTB BMX - совместима с Shimano, SRAM, FSA и Gaint от Marcus Block

With a 104bcd and an English threaded design, the bottom bracket is worth the price without the cranks. And a free mystery chainring? I have ridden 50 ish miles so far. No creaks, no slips, and smooth pedaling.Pros:For low to mid end bikes - mountain, gravel, or General 1x - this is a great upgrade from square taper. Plus the cranks on your bike are probably heavier than these. Free weight savings…Want to go 1x, these are a great option at <$50.Want to get better cranks or need to replace the BB? You now are in the hollow tech/dub category of quality high end components.Cons:Can’t choose the chainring. The cranks are a bit fiddly to learn how to install. Need a torque wrench to dial things in, unless you trust yourself.The center spindle is hollow? This is a great way for corrosion to build up… My version weighted in at <700g so not light by any means.That’s all folks. Will update at 500 mi or if things happen.
