Very light but usable stem with bonus extras at a great price

It may not look much, but Bontrager’s RXL mountain bike stem is a seriously lightweight performer for the money.

The simple cold-forged 7050 T6 aluminium body means no extra machining costs for a price that’s half of most of its super-light competitors. It’s done accurately enough to use this 114g waif for everyday trail riding without worry though.

There is more flex than usual if you really wrench it, but that’s par for the course for diet stems. The closely spaced four-bolt clamp with ovalised front and rear faces is designed to allow flex and reduce stress on matching super-light bars. Bontrager boost value by including a star-fangled steerer nut and a handful of spacers too.
