27.5″ – AM740 / EN740 – 46mm Carbon Rim

27.5″ – AM740 / EN740 – 46mm Carbon Rim

New for 2017, the AM740 / EN740 is Light Bicycle’s premium 27.5” plus rims.

Time to upgrade those super heavy alloy plus rims that have been dented into oblivion!

Plus sized tires are heavier, so often riders will use paper-thin sidewalls to reduce rotational weight as much as possible. With the AM740’s you will drastically reduce weight so you can afford to run more legit tires that won’t be sliced and diced and costing you downtime (and cash!).

Not only are they dramatically lighter, they are stronger as well. Alloy rims at low pressure dent very easily and ride sluggish. With the AM740’s you can unleash a new level of performance from your plus bike.

Please note that the price is per rim. We stock rims in UD Matte and a 32h hole count.

Special orders for custom hole drilling and finish can be ordered below.

Full AM740 wheelsets available with Onxy & I9 Hubs

  • *Rim Version

    The AM version or Standard version is the most popular version of the rim and the best choice for most riders.
    The "EN" or Heavy Duty version is 50g heavier and stiffer due to the additional reinforcement. The thicker walls can handle heavier (200lbs+) and extreme enduro riders. For most riders it is only used on the rear wheel. (See the difference in rim construction.)
    Adding the EN / Heavy Duty option may result in a delay in shipping. Please contact us if you are in a rush and we can confirm inventory levels.
