29 inch bike derailleur hanger: what BERG 3.0 RHS does and does not identify
A 29 inch bike derailleur hanger request should identify the frame-side part, rather than only the rear derailleur. Kross describes an RHS System of replaceable hangers on the BERG 3.0 page. That is useful construction information, but the inspected paragraph does not name the exact replacement hanger's part number.
Find the 29 inch bike derailleur hanger information under RHS
Kross's RHS passage describes a replaceable-hanger system and says threads are placed on the hanger or a special nut. Keep the alternatives in that description. It does not establish which detailed hardware arrangement is fitted to every individual bicycle being discussed.
The Black Glossy BERG 3.0 is the complete-bicycle reference here. Its configuration list contains both 27.5-inch and 29-inch choices. State the exact frame-and-wheel option when seeking a frame-specific spare, instead of reducing the enquiry to a wheel diameter and the Kross name.
Do not replace the missing code with M310
The equipment table separately names Shimano Altus M310 as the rear derailleur. That designation identifies the shifting mechanism in the published list. It does not supply the absent frame-hanger number, even though the two parts meet in the rear transmission area.
Likewise, RHS is the name of the described system, rather than a unique order code printed in the inspected paragraph. A search result offering a Kross hanger may be a useful lead, but the shared brand name or a similar outline does not establish the exact match.
Make the enquiry specific enough to resolve the missing identity
Give the supplier the model, complete configuration and clear photographs of the actual rear frame attachment and existing hardware. Include any readable markings. Ask for confirmation of the applicable part and its necessary hardware, rather than requesting an unspecified hanger by wheel size.
The historical FOCUS photograph shows another mountain bicycle's rear transmission area and a 50-559 tyre marking. It illustrates where the frame and derailleur come together, without identifying a BERG hanger or proving that the pictured attachment is interchangeable. No missing Kross part code can be recovered from that unrelated frame.
If the enquiry follows an impact or damaged shifting hardware, explain that history and arrange an assessment of the actual assembly. Identifying a replaceable part alone does not assess the surrounding frame. This guide gives no straightening method or installation torque.
The 29-inch bike references support model browsing. The Kross family introduction provides context, while the replacement decision still needs the frame-specific answer absent from the short RHS paragraph.
FAQ: RHS and the missing part number
Does Kross describe replaceable hangers?
Yes. That is the purpose identified in its RHS technology passage.
Does M310 identify the frame hanger?
No. It is the separately listed rear-derailleur designation.
Does the RHS paragraph provide a hanger code?
No. The inspected passage leaves the exact replacement part number unstated.
