Transition derailleur hanger guide: Where the FF-1 Fits
This Transition derailleur hanger guide addresses a specific legacy part: the FF-1, manufacturer part number 93.6601. The useful question is whether an identified frame appears in its compatibility list. A hanger that resembles the removed part, or a listing that mentions the same model family, should still be checked against the exact frame version and stated years.
Transition derailleur hanger guide to the listed versions
The official FF-1 product page includes the following legacy frames among its compatibility entries. This is an extract relevant to the models covered in this reference series, rather than a complete reproduction of the manufacturer’s list.
| Frame family | Listed versions | Listed years |
|---|---|---|
| BottleRocket | V1, V2, V3, V4, V5 | 2006–2011 |
| Covert | V2, V3 | 2009–2011 |
| Bandit | V1 | 2011 |
Read across the whole row. “Covert” alone is less specific than the manufacturer’s entry, and the Bottlerocket row does not establish compatibility with every later frame using that name. If your version is unresolved, leave the proposed hanger unresolved too.
The part and its mounting hardware are separate questions
Transition explicitly states that mounting hardware is not included with this hanger. Include the existing fasteners and their condition in your assessment instead of assuming that a product called a kit contains everything required for installation.
When asking a supplier for help, name the FF-1 and its part number, then identify what is missing from the bicycle. “I need a hanger” and “I need a hanger plus the correct mounting hardware” are different requests. A precise request reduces the chance of discovering another missing component only after the parcel arrives.
Resolve identification before treating the photograph as evidence
The historical Bandit photograph gives a clear view of a legacy drivetrain area, but it is not a dimensional inspection of the hanger. Use it to recognize the kind of bicycle under discussion, not to approve a replacement by silhouette.
For your own frame, retain clear photographs of the dropout and removed part, any readable markings, and the frame-identification evidence. Compare those with the dated manufacturer entry. If details conflict, ask Transition to resolve them before ordering rather than selecting whichever detail best supports the purchase.
FAQ about the FF-1 hanger
Does the FF-1 fit every Transition bicycle?
No. The manufacturer provides a specific compatibility list, including version and year limits for these legacy models.
Does the listing include mounting hardware?
No. The official page explicitly excludes it. Establish which fasteners are required separately.
Does a listed hanger resolve every shifting problem?
The compatibility entry only establishes the manufacturer’s stated frame fit. A mechanic must assess the actual bicycle’s condition and the rest of its drivetrain.
Use this Transition derailleur hanger guide when building a precise parts request. The separate shock-bolt reference applies the same attention to mounting position, while Transition’s brand page connects the ownership articles.
