1 Measure the frame's headtube length (including headset cups or attachments that cannot be easily taken off.)
2 Measure the diagonal length between the forward-most point (at the center of the headtube) to the furthest point of the frame (usually the derailleur hanger on geared bikes).
3 Use the chart below to determine your frame’s Transfer Case size.

Note: Frames with a headtube or diagonal length measurement greater than what’s listed won’t fit.
135L 150L
Headtube length (cm) Diagonal length (cm) Headtube length (cm) Diagonal length (cm)
12 ≤101.1 15 ≤106.4
13 ≤100.6 16 ≤105.9
14 ≤100.2 17 ≤105.5
15 ≤99.7 18 ≤105.0
16 ≤99.2 19 ≤104.5
17 ≤98.7 20 ≤104.0
18 ≤98.3 21 ≤103.5
- A frame with an 18cm headtube length and a measured diagonal of 98cm will fit in the 135L Transfer Case.
- A frame with a 20.5cm headtube length and a measured diagonal of 100cm will fit in the 150L Transfer Case.

In general, most travelers will prefer the smaller Transfer Case (135L) if their frame size allows for it. If your frame dimensions exceed the dimensions listed above by only a few millimeters, keep in mind that the Case’s side panels have thick foam padding that provides leeway and will still allow it to fit. Write to us at if you have any questions about fitting.


In regards to cable routing, as long as the bike's cables and housing do not prevent the fork from being removed, it will fit inside the Transfer Case. Frames with fully integrated cables or housing are not compatible inside the Transfer Case.
The Transfer Case was not intended for frames that feature an extended seat tube which acts as a seatpost. However, some frames with this type of seat tube are short enough and will fit in the Transfer Case. Please email us with your frame information and seat tube length measurements and we can see if your ISP frame will fit!
