Bombtrack Hook Wheel Sizes: Separate XS–S and M–XL Builds
Bombtrack Hook wheel sizes divide the saved steel-Hook build into two groups: XS and S use 650B, while M through XL use 700C. That makes frame size part of the wheel description. A listing that says only “Hook wheels” leaves out the distinction most likely to matter when comparing a smaller bicycle with a medium display bike.
Bombtrack Hook wheel sizes follow the frame group
The manufacturer’s saved specification pairs XS and S with WTB Resolute tyres marked 42-584 at both ends. Medium, Large and XL instead receive WTB Venture 40-622 entries. Keep the complete markings, including the number after the hyphen. Recording only the first number would hide the different wheel-size groups that the page explicitly describes.
The local parent offers XS, S, M, L and XL configurations. The catalogue listing is Bombtrack Hook Bike — Metallic Black. Its configuration labels identify the options in that listing; they do not independently confirm that every component still follows the saved manufacturer build.
The rim name does not erase the diameter split
WTB ST i19 double-wall TCS 2.0 rims appear in the front and rear rows, with 32 holes. The repeated rim family name can make the builds look identical in a short equipment summary. Read it alongside the size-specific tyre rows instead of treating the shared name as evidence that the complete wheels are interchangeable.
The source also uses tubeless wording for the rim and tyre package. That describes the published components, without documenting the sealing arrangement inside an individual wheel. It supplies no pressure, sealant quantity or evidence that a particular used bicycle presently runs without inner tubes.
Compare the complete size you are considering
For a wheel enquiry, give the supplier the frame label and the actual tyre and rim markings together. The saved split describes original build choices; it does not approve converting a small Hook to the larger wheel format. A similar-looking Hook EXT, another colour offer or an older bicycle in a photograph is a separate record.
The historical Hook 2 MY19 image illustrates the gravel family without establishing this wheel specification. Use the Bombtrack topic to find the model context and the existing brand introduction for the wider range. Neither replaces the two explicit frame-size groups.
FAQ
Which group uses 650B in this record?
XS and S are the two sizes assigned that wheel format.
Are the M–XL tyres listed as Resolute 42-584?
No. Their rows name Venture 40-622 instead.
Does the common ST i19 name approve swapping wheel formats?
No. The shared rim label does not establish a complete conversion.

The wheel and tyre entries distinguish the Resolute/650B smaller-frame package from the Venture/700C larger sizes. See the manufacturer’s saved steel Hook record (https://bombtrack.com/products/bombtrack-hook), captured 26 October 2026 and reread 5 November 2026.
