Fit varies by model, but common cup diameters range roughly from about 55 mm up to 82 mm. Many models target the mid-range sizes (around 56–70 mm or 60–70 mm), so check the specific listing for exact fit.
Depending on the model, these holders are described for mounting to seat posts or to handlebars (using a base or handlebar mount). Mounting options vary by product, so confirm the intended location in the listing.
Thread and mounting specs vary by model. Example thread sizes found in listings include metric screws such as M4 x 0.7 and M5 x 0.8. Mounting-hole pitch measurements also differ by product, so verify the exact size in the listing.
Some holders combine aluminum alloy and plastic to provide a sturdy structure while keeping weight and cost down—listings describe this mix as improving durability and service life.
Package sizes vary: some listings sell a single holder (1×) while others offer two-pack sets (2×). Check the product description to confirm the quantity included.
Cup-holder mounting hole pitches listed are around 5.5–6.5 cm (55–65 mm). Fit-for base hole diameters in the listings range roughly from about 14 mm up to 40 mm. Required sizes depend on the specific model, so verify the measurements in the product details.
