About The Factor Ostro Gravel Carbon Premium Package Gravel Bike Frameset With Wheels
The Factor Ostro Gravel Carbon Premium Package pairs the OSTRO Gravel frameset with a Black Inc THIRTY FOUR carbon wheelset — no groupset included, so it's built for a rider who already knows what drivetrain they want to run. The frame is molded from TeXtreme, Toray, and Nippon Graphite pitch-based carbon fiber and paired with the OSTRO Wide Stance Fork, carrying over the "win everywhere" design brief from Factor's OSTRO VAM road racer into a gravel platform built for speed on mixed surfaces.
Factor used a zoned aero strategy: the front of the bike, which meets clean airflow, is shaped for drag reduction, while the rear prioritizes low weight and ride quality where air flow is turbulent. Most of that work went into an all-new head tube shape that manages the laminar separation bubble near the front of the tube — a detail borrowed from aerospace design. The frame carries a 45mm tire clearance rating, verified with 4mm of clearance per side to ISO standard, and rode to a top-10 finish at the 2022 Unbound 200.
Who It's For
- Riders who already own an electronic groupset and want to build it onto a race-oriented aero gravel frame, since this package ships as a frameset with wheels only.
- Gravel racers prioritizing front-end aerodynamics without sacrificing 45mm tire clearance for rough or wet terrain.
- Riders planning a full custom build and comfortable specifying their own bottom bracket standard, cockpit, and finishing kit.
- Riders wanting a complete bike out of the box, or planning to run a mechanical (non-electronic) drivetrain, should look elsewhere — cable routing and compatible components are electronic-only.
What to Look For
- Bottom bracket standard: ships with CeramicSpeed T47A aluminum cups; CeramicSpeed bearings are also available for DUB, 24mm, or Ultra-Torque cranksets, so confirm which spindle your groupset uses before ordering.
- Cockpit fit: the Black Inc integrated aero barstem comes in an 80mm reach / 120mm drop with multiple stem lengths and bar widths available — get a proper fit, since this is an integrated setup rather than a swap-any-stem cockpit.
- Wheel and tire pairing: the included Black Inc THIRTY FOUR wheelset is 700c; the frame's 45mm clearance applies to both 700c and 650b, so factor that in if you're planning a 650b build later.
Key Features
Frame and aero: The TeXtreme/Toray/Nippon Graphite carbon layup and reshaped head tube are the core of the frame's drag reduction, targeted at gravel racing speeds rather than road-race speeds — Factor says the gain is measured in minutes over a long event, not seconds.
Drivetrain compatibility: The frame supports SRAM's Universal Derailleur Hanger (UDH), which standardizes derailleur mounting position for smoother shifting, lets the hanger rotate rearward in a crash to protect the derailleur, and includes a chain-catching lip so a dropped chain can't lodge between hanger and frame. Combined with electronic-only compatible components and fully internal cable routing, it's built around current wireless drivetrain standards.
Braking and clearance: Disc brakes are rated to a 160mm max rotor front and rear, with 12x100mm front and 12x142mm rear thru-axles, and support for chainrings up to 52 teeth.
Wheels and bearings: The Black Inc THIRTY FOUR wheelset is 700c. The headset runs CeramicSpeed SLT bearings in a 1.5" upper and lower head tube, and frame weight comes in at 950g.
Rider Intent Summary
- Biggest strengths: aero-shaped frame construction, sub-1kg frame weight, UDH and electronic-drivetrain compatibility, and a 45mm tire clearance rating verified to ISO standard.
- Tradeoffs: sold as a frameset with wheels only (no groupset), the integrated aero barstem limits stem swaps, and compatible components are electronic-only.
- What makes it different: a zoned aero head tube shape adapted from the OSTRO VAM road bike specifically for gravel-speed airflow, backed by a top-10 finish at the 2022 Unbound 200.
Victory's Take
At Victory Bicycle Studio, we'd point this package toward a rider who already has electronic shifting and a clear build plan and wants Factor's aero frame and Black Inc wheels underneath it — bring us your parts list and we'll handle the fit and the build.

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.
