Question:

I bought from a local bike shop a pair of Thule TC2 Wheel Tray End Caps. However, they did not fit my Thule Big Mouth bike rack. I see on your website you have two end caps for this rack, Code: 853-5424 and Code: 753-3236. Which one will fit my rack?

Expert Reply:

It's very likely the latter, but it depends on the specific Thule Big Mouth rack you have, as there were two of them, the original Big Mouth Upright 599XT and the Big Mouth 599XTR. It is likely the 599XTR, as they were around far longer.

The original 599XT was only out from 1999 through 2003, while the 599XTR was available from 2004 to the beginning of 2017. So you'll need to know what rack you have, specifically to get the correct end cap.

- Big Mouth 599XTR (2004 - 2017): Replacement Wheel Tray End Cap # 753-3236

- Original Big Mouth Upright 599XT (1999 - 2003): Replacement End Cap # 853-5424
