Choose Crank Pullers, Cap Tools and Bottom-Bracket Contacts

Separate arm extraction, cap adjustment, cup engagement and counterholding to buy the contacts your actual drivetrain needs.

Compare the contact before completing the tool list
Job	Examples	Purchase decision
Crank extraction	CCP-22 / CWP-7	Handled format versus two contact feet and separate driving wrench
Cup engagement	BBT-9 / BBT-19.2 / BBT-22	Contact geometry first; actuation second
Small adjusting cap	TL-FC16	Separate from cup removal and crank extraction
Nut or lockring	CNW-2 / HCW-5 / LRT-4	Different surfaces to restrain or turn
Retention	BBT-RS	Accessory, not the cup-engagement socket

Start with the component you need to move

A tool list for a complete drivetrain service can contain several unrelated contacts. Removing a crank bolt, pulling an arm, operating an adjusting cap and turning a bottom-bracket cup are different steps. Identify which is actually required on your exact crank and bottom bracket before buying a combined-looking tool.

This matters when replacing one missing tool: a cup socket does not become a crank puller because it clears the same spindle. The component maker’s service arrangement determines whether a puller or a different extraction system is used.

Compare the puller foot as well as its handle

CCP-22 supplies a long integrated handle for its supported extraction scope. CWP-7 has a compact body and two rotating feet: 11.3 mm and 16.3 mm, assigned to different supported spindle contacts. Both require M22 × 1.0 extractor threads in the crank arm.

CWP-7 is worth comparing if the workshop maintains both its named small-foot applications and ISIS or Octalink systems. It needs a separate 15 mm or suitable adjustable driving wrench. Prefer the handled CCP-22 when its own supported systems cover the need and that complete extraction format is the useful difference.

Choose cup geometry before choosing a driver

BBT-9 and BBT-19.2 share a related 16-notch, 44–45 mm major-diameter cup contact, but differ in actuation and permitted jobs. BBT-9 includes a handle and a second adjusting-cap contact. BBT-19.2 accepts separate manual driving equipment and excludes shallow rotor-lockring use.

BBT-22 addresses a 20-spline cartridge fitting. BBT-18 has an eight-notch contact, BBT-4 a six-notch SC-S/AC-H contact, and BBT-79.3 its own 12-notch geometry. These are not competing sizes of one universal socket. Match the actual cup profile, diameter and spindle clearance.

Buy cap and counterhold contacts for their own jobs

TL-FC16 operates its named crank-arm adjusting cap. CNW-2 holds supported slotted chainring nuts. HCW-5 engages its bottom-bracket lockrings, while LRT-4 addresses its specified Shimano direct-mount chainring lockring. Their different jobs explain why a small drivetrain toolkit can legitimately need more than one.

If you already own BBT-9 and its adjusting-cap contact matches the task, a separate cap tool may duplicate that function. Compare the contacts you have before adding another tool solely because it is listed beside the crank parts.

Complete retention and actuation separately

BBT-RS provides retention for its documented socket and spindle combinations. It is not a cup socket and should not be budgeted as a complete removal tool. Confirm which matching socket and driving tool must be supplied separately.

A drive size establishes one connection, not a torque value or permission for powered actuation. Keep the selected tool’s manual-use limits and the exact component’s service requirements with the final purchase decision.

Questions before you choose

When does CWP-7 add coverage over CCP-22?

Its two contact feet cover the named small-foot and supported ISIS or Octalink applications. Confirm the actual crank interface and provide its separate driving wrench.

Can a Shimano brand label identify the right bottom-bracket tool?

No. Compare the exact cup model, notch or spline pattern, diameters and spindle clearance. Several tools here engage fundamentally different fittings.

Which small tool might duplicate a contact I already own?

TL-FC16 may overlap the adjusting-cap role of a matching BBT-9. Compare the exact supported cap before buying both; the cap function is separate from cup engagement.
