Compatibility, Size and Fit
Check the seatpost diameter before choosing this rack: the stated limit is under 33.3 mm. Although it is described as fitting most bikes, including mountain and road bikes, that broad claim does not establish fit on every bicycle. Check the mounting position and clearance on the specific bike.
What to Compare Before Buying

- Length: Compare the adjustable 13.8 to 19.7 inch range with the space available on the bicycle.
- Load: Keep the expected carried weight within the 22 lb maximum.
