About The Bontrager Elite 120mm 17° 31.8mm Black Stem
The Bontrager Elite is a 120mm, 17° rise alloy stem with a 31.8mm bar clamp for road or mountain bikes. A 17° rise lifts the bar noticeably for a more upright position.
It is approved for carbon handlebars and carbon steerer tubes, and uses M5 countersunk, corrosion-resistant steel bolts with a 5.2Nm torque spec. Blendr Elite compatibility lets you mount lights, a computer, and other accessories to the stem system.
Who It's For
- Road or mountain riders with a 31.8mm handlebar who need a 120mm, 17° stem.
- Riders running carbon bars or carbon steerers, which this stem is approved for.
- Riders who want Blendr Elite accessory mounting.
- Riders with a 35mm-clamp handlebar should look elsewhere.
What to Look For
- Bar clamp: 31.8mm. Steerer diameter is not listed for this part, so confirm it against your fork before ordering.
- Length and rise: 120mm at 17°. Both change hand position, so choose them from your fit.
- Torque: M5 bolts at 5.2Nm; use a torque wrench, especially with carbon parts.

Victory's Take
At Victory Bicycle Studio we fit a 120mm, 17° stem when a rider needs a long reach but a higher bar than the frame's stack allows.

Frequently Asked Questions
Do you offer free shipping?
We do offer free shipping on non-bike orders over $100. We do not offer free shipping for bicycles unless it is a one time promotion. Generally, bike shipping will cost $150 and that covers just the shipping of the bike with no assembly. If you were to bring that bike to your local mechanic or bike store, you would pay them their assembly fee. If you choose our Professional Assembly option for $200, our service technicians would assemble the bike before shipping and then re-pack the bike safely for transit. When you receive the bike you would attach the front wheel, attach the seatpost/saddle, and raise the handlebars and clamp them. Those three items do have to be detached to minimize or eliminate the chance of damage in transit.
How much does shipping cost?
For orders of parts, accessories, apparel, etc. on orders under $100, shipping is a flat rate of $9.99. Regular bike shipping without assembly is $150, bike shipping with Professional Assembly is an additional $200 (so $350 in total which includes the $150 of regular shipping). Our White Glove Delivery option is $699 and that will cover the assembly of the bike and our White Glove Delivery partner delivering your dream bike to your front door, ready to ride!
