About The Factor Ostro Carbon Sram Force XPLR Gravel Bike
The Factor Ostro Carbon with SRAM Force E1 XPLR and an integrated power meter is a race-focused gravel bike built for riders chasing speed on mixed terrain, whatever the surface. Its TeXtreme, Toray, and Nippon Graphite pitch-based carbon fiber frame uses a zoned aero design, an aerodynamically shaped head tube up front paired with a lighter, more compliant rear end, resulting in a 950g frame weight and a measured 45mm tire clearance that lets it move from smooth gravel roads to rough double-track without swapping bikes.
Every component on the build reinforces that intent. The SRAM Force E1 XPLR 1x13-speed groupset (44T crank, 10-46T cassette) pairs wireless shifting with a built-in power meter, Black Inc's Thirty Four carbon wheels and Integrated Aero Barstem handle the aerodynamics and ride feel, and CeramicSpeed bearings run throughout the headset, bottom bracket, and hubs to cut drivetrain friction. The frame also supports SRAM's Universal Derailleur Hanger (UDH), keeping it compatible with current and future wireless drivetrains.
Who It's For
• Gravel racers and fast group-ride riders who want an aero-optimized frame, ridden to a top-10 finish at the 2022 Unbound 200.
• Riders who want a wireless 1x13 drivetrain with a power meter already integrated into the build.
• Riders who need up to 45mm of tire clearance for mixed or rough gravel terrain.
• Riders who value low-friction componentry (CeramicSpeed bearings) over the lowest price point.
• Consider a different bike if you need 2x gearing, a suspension-equipped adventure setup, or tire clearance beyond 45mm for loaded bikepacking.
What to Look For
• Bottom bracket bearings are available for DUB, 24mm, or Ultra-Torque cranks, so confirm which matches your groupset before ordering.
• Seatposts come in 0mm and 20mm setback, and saddle rail clamps in 7x7 or 7x9, both of which affect saddle fit and position.
• The Integrated Aero Barstem has a fixed 80mm reach and 120mm drop, though multiple stem lengths and bar widths are offered, so a professional fit check will confirm sizing.
Key Features
Frame and fork: The OSTRO Wide Stance Fork and pitch-based carbon frame use a zoned aero strategy, concentrating aerodynamic shaping at the head tube, where airflow is cleanest, while keeping the rear of the frame focused on weight and ride quality. A 1.5" head tube (upper and lower) with CeramicSpeed SLT bearings supports precise steering.
Drivetrain and braking: SRAM's Force E1 XPLR groupset delivers 1x13-speed wireless shifting with a 44T crank and 10-46T cassette, plus disc brakes with up to 160mm rotors front and rear. UDH compatibility keeps the frame open to future SRAM drivetrain updates.
Wheels and tires: Black Inc's Thirty Four wheels use a 34mm depth and 25mm internal width, a hookless tubeless-ready rim, and CeramicSpeed hub bearings. Tire clearance is a measured 45mm.
Cockpit: The Black Inc Integrated Aero Barstem adds a 7-degree flare for extra control in the drops, plus an integrated GoPro-style mount for a computer or camera.
Rider Intent Summary
• Biggest strength: A frame and component build purpose-built for gravel speed, with a top-10 finish at Unbound 200 as real-world proof.
• Tradeoff: A 1x-only drivetrain and race-oriented geometry mean less versatility for heavy bikepacking loads.
• What makes it different: An integrated power meter, CeramicSpeed bearings throughout, and a zoned aero frame design, combined in one build.
Victory's Take
We see the Ostro Carbon as one of the more complete race-ready gravel builds we carry. The aero details and CeramicSpeed spec are what our fit and service team gets asked about most, and if you're racing gravel, it's worth a test ride at Victory Bicycle Studio.

Frequently Asked Questions
How is the bike packaged and how long does delivery take?
All bikes are securely packaged to ensure that damage doesn't occur during shipping. All parts of the bike are padded and if needed, zip tied to minimize or eliminate movement inside the box. Once a bike is handed to the shipping company (usually Fedex or UPS), depending on your location, delivery will range from 1 day to 8 days. If you do choose the option for Professional Assembly or White Glove Delivery, this can add anywhere from 2 days to 5 days to the lead time.
Can I finance the purchase of my new bike?
Yes. Simply select the Shop Pay Installments option which will allow you to buy now and pay later. Shop Pay Installments is powered by Affirm. If you would like to determine your spending limit, simply download the Shop app or the Affirm app on your smartphone and after you create an account on one of these apps, the app will let you know what is your spending limit.
Can I return the bike if it doesn't suit my needs?
Our return process is as follows. The customer is responsible for the return label ($150). Once the returned bike arrives at our warehouse, our team will inspect it and make sure it is in new condition and undamaged. Once we verify, we will process the return and issue a refund to the original payment method on file. To clarify the amount refunded, it would just be the amount of the bike (and tax if applicable) less the $150 shipping label that we provided, but the original shipping is not refunded. So if the original bike cost $4,500 and shipping was $150 (so you paid $4,650), you would be refunded $4,350 (the $4,500 less $150 for the return label) assuming the bike was returned in new and un-used condition and within the 30 day return period.
What does the warranty of my new bike or product cover and what is the warranty period?
Depending on the bike or any product, different companies have different warranty policies. If you do ever have an issue with your bike or any product, simply email us at online@victorybicyclestudio.com and we will assist with any warranty issues and clarify the warranty for the affected product.
Can I have my bike serviced at any bike shop?
Typically, to avoid any issues with your warranty, you should bring your bike to a certified mechanic or bike store for that bike (i.e. if you have a Trek bicycle, you should bring the bike to be serviced to a local bike store that is an authorized Trek dealer). If you need assistance, simply email us at online@victorybicyclestudio.com and we can direct you to a certified dealer of your bike.
Do you ship bikes internationally?
We unfortunately do not ship bikes outside of the 48 contiguous states of the United States. We do recommend for international customers to open (or use a current account) account with a freight forwarding company. If you use a freight forwarding company located in the U.S., make sure to put your billing address for a dedicated credit card as the same address as the freight forwarder so that you don't have any credit card or payment method issues).
Once you do this, simply place an order with us and we can ship to the U.S. address as long as the credit card doesn't get rejected. Once the freight forwarder has the box/order/shipment, you would instruct them to then ship to you in your home country and they would charge you their own shipping charge to ship to your international address.
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!
How can I track my order?
When you place your online order, you will receive an instantaneous email update with your order number and order details, and shortly after, you will receive a follow up order email with the tracking number for your order. If you still need assistance with your order, feel free to email us at online@victorybicyclestudio.com and we will respond asap.
What happens if my package arrives damaged?
If your package arrives damaged, email online@victorybicyclestudio.com with pictures of all angles of the box and pictures of the damaged product and we will work with you to either send a new replacement asap and coordinate return (or re-imburse you for labor or costs incurred to fix the issue at your local bike store).
Are pedals included with the bike?
If you do not see pedals in the bullet point product specs on the product page, the bike does not come equipped with pedals. Many manufacturers do not spec bikes with pedals, so they are often purchased separately.
If I only pay the $150 for bike shipping, can I assemble the bike on my own?
Victory Bicycle Studio highly recommends that you bring your bike to your local certified bike store for the brand of the bike that you purchased. If you do attempt to assemble the bike and damage occurs, this may result in your warranty not being honored. For that reason, we do highly recommend to select our Professional Assembly option for $299.
