KhodaaBloom KESIKI Bottom Bracket: BSA and Square Taper Describe Different Things
The KhodaaBloom KESIKI bottom bracket is described as a sealed-bearing square-taper cartridge in the saved specification. BSA appears separately in the frame description, while the crankset has its own model name and dimensions. Those entries provide a useful identification starting point, but they do not supply every measurement needed to order a replacement.
KhodaaBloom KESIKI bottom bracket: three source locations
The frame line reads AL6061-EAST BSA 135mmQR FlatMountDiscBrake. Retain BSA as the published frame-side notation. The adjacent references to rear spacing and brake mounting do not become bottom-bracket dimensions simply because they occur in the same line.
The BB row supplies the construction description: a sealed-bearing square-taper cartridge bottom bracket. The crankset row then identifies Shimano FC-TY501-2, 46–30T, 170mm W/CG. Combining those three rows is more informative than asking for an unspecified cartridge solely from the name KESIKI.
Do not invent the missing shell and spindle figures
The complete saved page does not give a bottom-bracket shell width or square-taper spindle length. Nor does it supply an installation torque. A familiar-looking crank or another bicycle's BSA specification cannot fill those gaps with verified KESIKI numbers.
The crank's 170 mm entry is its listed crank length, while 46 and 30 are the published chainring tooth counts. None of those figures labels a bottom-bracket spindle length. Copying the full crank identifier into an enquiry preserves the part information without turning a neighbouring number into the missing measurement.
Identify the actual assembly before buying
The KESIKI Dark Blue listing provides the bicycle identity and repeats the FC-TY501-2 crankset record. For an existing machine, add any readable fitted-part identification and known replacement history. A published original specification is not evidence that a previous owner retained every component.
The different road bicycle in the photograph locates the external crank area. The hidden bearing and spindle cannot be identified from that overview. This is why a parts discussion needs more than a photograph of the crank beside the frame.
Ask a qualified supplier or workshop to confirm the required complete assembly and applicable information for the actual bicycle. This reference gives no removal, spacer, chainline or tightening procedure. The brand background article explains the wider range; the KhodaaBloom article hub keeps the specific model enquiry in context.
FAQ
What construction does the BB row describe?
It describes a sealed-bearing square-taper cartridge bottom bracket.
Is 170 mm the published spindle length?
No. That figure appears in the crankset entry, not as a bottom-bracket spindle measurement.
Can BSA alone complete a replacement order?
No. The saved record leaves other dimensions and the actual fitted assembly unresolved.
