Customer Reviews

The Paul BOXCAR Stem is an iconic stem from Paul Components, America’s high-performance bicycle component manufacturer. It is known for its clean finish, tough appearance, solid stiffness and distinctive machining quality.


One of the key strengths of the BOXCAR Stem is its balance of rugged looks and dependable rigidity. Whether installed on an MTB, cyclocross bike, single speed build or other custom bike, it gives the cockpit a more refined and distinctive component presence with a strong American CNC style.


The stack height is 36mm, which is relatively low and allows more flexibility when adjusting handlebar height and riding position. This is especially useful for riders who want to fine-tune cockpit setup, manage front-end height or work with limited steerer tube space.


The 4-bolt faceplate provides a secure grip on the handlebar, while the high-strength stainless steel T25 bolts offer reliable fastening. The 31.8mm bar clamp fits common modern handlebars, and the 28.6mm steerer clamp is designed for 1-1/8" steerer tube setups.


Available in silver and purple, with 70mm and 90mm length options and a +/- 15° angle, it can be selected according to riding position, frame geometry and bike color coordination. If you are looking for a high-quality stem with a strong look, solid structure and wide bike compatibility, the Paul BOXCAR Stem is a standout choice.


⚠️ Please note: this product includes the stem only. Handlebar, fork, top cap, spacers and display props are not included.
⚠️ Please confirm handlebar clamp size, steerer diameter, stem length and angle before purchase.
⚠️ Follow recommended torque values during installation to avoid over-tightening or insufficient clamping.
⚠️ Cockpit assembly affects riding safety. Professional installation and inspection are recommended.
