About The Bontrager Comp 60mm 7° 31.8mm Black Stem
The Bontrager Comp is a 60mm, 7° rise stem with a 31.8mm bar clamp, built from cast 6061-T6 aluminum for road, city, and mountain bikes. It is a straightforward alloy stem for riders who need a specific length to correct reach.
It is Blendr ready, so it works with Blendr Comp and Legacy Elite bases and mounts (sold separately) for lights and computers. A 4-bolt dual band bar clamp and an opposing 2-bolt steerer clamp with M5 corrosion-resistant steel bolts keep the hardware simple to service.
Who It's For
- Riders with a 31.8mm handlebar who need a 60mm, 7° stem on a road, city, or mountain bike.
- Riders who want to mount lights or a computer with Blendr Comp or Legacy Elite hardware.
- Riders with a 35mm-clamp handlebar should look elsewhere.
What to Look For
- Bar clamp: 31.8mm only. Steerer diameter is not listed for this part, so confirm it against your fork before ordering.
- Length and rise: 60mm at 7°. Stem length moves your hands forward or back by about the same amount, so choose it from your fit, not by eye.
- Accessories: Blendr Comp and Legacy Elite bases and mounts fit; they are sold separately.
Key Features
Cast 6061-T6 aluminum. Cast body construction in 6061-T6 alloy.
4-bolt bar clamp. Dual band design that, per Bontrager, retains stiffness while reducing weight.
2-bolt steerer clamp. Opposing bolt layout using M5 corrosion-resistant steel bolts.
Blendr ready. Compatible with Blendr Comp and Legacy Elite bases and mounts, sold separately.
Finish. Black.
Rider Intent Summary
- Biggest strengths: Simple, serviceable alloy stem with Blendr accessory compatibility.
- Tradeoffs: Cast rather than forged construction; weight and torque spec are not published for this listing.
- What makes it different: Blendr compatibility lets lights and computers mount to the stem system instead of crowding the bar.
Victory's Take
We often reach for a 60mm stem at Victory Bicycle Studio when a rider feels stretched on a city or trail bike and wants their hands closer without changing the bar.

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!
