Bottom bracket
Bottom brackets for older bicycles – Classic solutions for retro and city bikes
Do you have an older bicycle that needs an upgrade or a replacement bottom bracket? At Velovintage, you’ll find a carefully selected range of bottom brackets for classic bicycles—perfect if you ride a retro city bike, touring bike, or older road bike.
Square-taper bottom brackets – still the most common choice for classic bicycles
Most older bicycles are equipped with a square-taper bottom bracket (ISO or JIS standard). This type of bottom bracket is known for its durability and easy installation. We stock both sealed and adjustable models that fit a wide range of frames and cranksets.
Thread standards for older frames
We stock bottom brackets in the common thread types typically found on older bicycles:
BSA (British/English thread) – 1.37” x 24T, right-hand/left-hand thread
Italian thread – 36 mm x 24T, right-hand thread on both sides
French thread – Less common, but still relevant for certain vintage bicycles
Are you unsure which thread type your bicycle has? We’ll be happy to help you find the right solution.
Quality and compatibility
We stock bottom brackets from reputable manufacturers such as:
Joel bottom brackets – High quality with a Cr-Mo axle
SunRace – Affordable and reliable models
Tange Seiki – Japanese quality for retro projects
Our range covers various axle lengths (e.g. 107 mm, 113 mm, 118 mm, etc.), allowing you to adjust the chainline to suit your crankset.
Get your classic bicycle road-ready again
Whether you’re restoring a classic road bike or simply want your old city bike to ride like new, a new bottom bracket is often one of the best upgrades. It improves pedaling and stability while reducing creaking noises and play.
