Standardized Headset Identification System (S.H.I.S.):

The Standardized Headset Identification System (S.H.I.S.) creates a common language for describing modern bicycle headsets. The system provides comprehensive and scalable headset fitment information in a standardized format; making it easy to communicate headset requirements based on frame and fork interfaces. The system addresses the critical interface dimensions required to fit a fork to a frame, as well as bearing location/cup type. To determine fit, four dimensions are needed: (1) stem-clamp diameter of fork, (2) crown-race seat diameter of fork, (3) head-tube top inside diameter, and (4) head-tube bottom inside diameter. Bearing location and cup-type are identified as (a) external cup (EC), (b) semi-integrated or zero stack (ZS), or (c) integrated (IS).


EC: Bearings contained within cups that are located outside of the frame (external cup).
ZS: Bearings contained within pressed-in cups where the cup and bearings rest inside the frame (zero stack).
IS: Bearings that fit directly into a bonded or machined interface that is integrated into the frame (integrated).

Во-первых, у купленной рулевой колонки подшипники отличаются как цветом стали, так и цветом пыльника. Здесь подшипники похожи на "Hope IS52/40"
Во-вторых, имейте в виду, что в этой модели нижний подшипник ставится не на компрессионное кольцо. Кольцо цельное и его нужно забивать на шток вилки специальным набором инструментов или, как это сделал я, подручными средствами.

Не могу понять в чем дело, но получается так, что:
или рулевая свободно вращается, но шток вилки люфтит в верхнем подшипнике;
или же, затягивая больше болт топ кепа, рулевая колонка перестает люфтить, но и поворачивается с трудом.
По всей видимости компрессионное кольцо не расклинивает достаточно шток в подшипнике! При этом рулевая должна полностью подходить под Specialized Stumpjumper FSR Comp Carbon 6Fattie 2016 (об этом говорит и официальный сайт Cane Creek)

За эту стоимость я хотел бы приобретать продукт, с которым не буду иметь проблем...

Firstly, bearings of a purchased headset differ in both the color of steel and the color of the duster. Here the bearings are similar to "Hope IS52/40"
Secondly, keep in mind that in this model the lower bearing is not placed on the compression ring. The ring is integral and needs to be hammered onto the fork stock with a special set of tools or, as I did, with improvised means.

I can’t understand what’s the matter, but it turns out that:
- or the headset rotates freely, but fork stock is backlash in the upper bearing
- or, tightening the top cap bolt more, fork stock ceases to backlash, but does not turn freely.
At the same time, the headset should fully fit the Specialized Stumpjumper FSR Comp Carbon 6Fattie 2016 (the official website of Cane Creek also speaks about this)

For this price I would like to purchase a product with which I will not have problems...
