Norco Range 2018 Rear Axle: Check the Complete Thread Specification

Norco Range 2018 rear axle identification should begin with the complete specification, not “Boost axle” alone. Rear spacing is only one part of a replacement enquiry. The historical table also records the axle length, thread information and a Syntace identifier, while the assembly drawing shows that the hanger and cap are separate items around the interface.

Copy the complete Norco Range 2018 rear axle entry

The 2018 carbon technical table (https://www.norco.com/downloads/bike-spec-sheets/range-carbon-small-parts.pdf) lists 148 mm OLD for both C7 and C9. Its rear-axle row reads TA12/L171/TL20/M12×1.0 and identifies Syntace 148, part 913105-006. In a parts enquiry, keep all of those elements together: a 12 mm axle, 171 mm length, 20 mm thread length and the stated M12×1.0 thread.

A replacement with a matching diameter and hub spacing has not necessarily matched the remaining entries. Ask the supplier to compare the entire specification with the candidate part and the actual frame. If the existing axle has been replaced before, its markings are useful evidence, but should be checked against the frame record rather than accepted as proof that the earlier replacement was correct.

Keep the hanger, cap and axle distinct

The 2018–2019 assembly drawing (https://www.norco.com/cmsb/uploads/bikes/bikes/range-carbon-tech-support_003.pdf) labels the Syntace X-12 axle separately from the derailleur hanger and cap. Its hanger-plus-cap entry is 913015-001, whereas the detailed table's rear-derailleur-hanger row is 913015-001-1. These are source entries with different descriptions; do not erase the suffix or assume every package includes the same pieces.

Send the retailer photographs of the hanger, retaining cap and damaged or missing part, together with the frame identity. Say whether you need the axle itself, a hanger or the complete illustrated assembly. That is a more useful enquiry than asking for a generic Range hanger while leaving the required pieces unspecified.

The assembly's summary page abbreviates the axle notation differently from the detailed table. Retain the table's explicit thread entry in the enquiry instead of interpreting the compressed summary as a different pitch. Any disagreement with the installed part should be resolved before a component is threaded into the frame; visual resemblance does not settle thread compatibility.

This is an identification record rather than a torque or installation recipe. The assembly document separates instructions for different pieces and includes a qualification for the axle manufacturer's specification. A qualified technician should use the applicable instructions for the actual components rather than one number borrowed from an unrelated fastener in the diagram.

FAQ

Does 148 mm describe the axle's complete length?

No. It is the listed rear spacing; the detailed axle entry separately gives L171.

What thread does the detailed table specify?

It explicitly lists M12×1.0, together with a 20 mm thread-length entry.

Is the hanger-plus-cap code identical to the hanger row?

No. The drawing gives 913015-001 for hanger plus cap, while the table lists 913015-001-1 for the hanger.

Use the pivot-parts enquiry guide if the problem lies in the adjacent linkage instead. Keep those two repair requests separate when consulting the Norco model documentation.
