Description
Project 321 was the first in the aftermarket Lefty game and have been the number one reseller of Leftys and Lefty accessories for several years. Needless to say, we have quite a bit of experience and have had time to refine our design. Our 1.0 Lefty hub is purpose built and not just repurposed from an ISO hub like some of our competitors’ hubs. This means that every little feature about it is dialed-in and there are no compromises. For example, the flange spacing has been optimized to yield a stronger wheel by improving bracing angles. We were also able to shave some weight off of the hub by shrinking the drive-side flange and adding lightening holes. When combined, all the small details come together to create the best Lefty hub money can buy. Our 1.0 Lefty hub can be used on the Lefty 1.0 Hybrid and older forks or on the Supermax that has the appropriate brake adapter installed. Our 2.0 / Supermax Lefty specific hub can be found here: 2.0 / Supermax Lefty Hub
Thoughtfully angled flanges. This is a big one, folks. We are the only manufacturer on the market to create a little to no-touch environment that allows the spokes to touch the hub only at the bend and nowhere else. This creates a more stable and true wheel and eliminates any unnecessary stress on the spokes. We have achieved this by adjusting the angle of the flanges slightly inward to mimic the angle of the spokes and remove any interference. On many of our competitors’ hubs the flanges are vertical causing the spokes to have to bend around the flange creating a stress point and reducing the strength of the wheel.
Rotor bolt holes are form tapped which creates a stronger, cleaner thread than the more common method of cut tapping.
Hubs also feature a CNC machined logo versus a lasered or stickered logo.
Rigid Quality Control. This is something we take VERY seriously. You will not receive a hub with a scratch or ding. We believe it is your job to try and tear this baby up, not ours. We also maintain tight controls on anodizing to provide consistent colors and use an extra long seal to preserve color. Unfortunately, fading is part of the nature of the anodizing process, but the extra long seal helps maintain the original brilliance as long as possible.
Outstanding Customer Service. We pride ourselves on our knowledge and our availability. A real person still answers the phone and we have team of knowledgeable sales and technical advisers available to help you over the phone or via email. Our response times are normally very fast, often same day and our shipping team works hard to get your product as quickly as possible (often same day).

What does 1.0 mean/stand for? A 1.0 or “Classic” Lefty is one that is model year 2015 or prior and has a 32mm stanchion. This distinction is important because these Leftys do not have the extended axle spacing that the newer 2.0 / Supermax Leftys have and they must use a 1.0 Lefty Hub.
+
Can I use this hub with a 2.0 or Supermax Lefty? It depends on which 2.0 / Supermax Lefty you have and if an adapter exists for it. Here is a chart that shows you the possible combinations:

Can this hub be converted to an ISO Front hub? No, there is no conversion kit to turn this hub into an ISO Front hub.

How do I know if my bearings need to be replaced? There are a few factors to consider when it comes to evaluating the condition of your bearings. The amount of ride time you have on them and the conditions in which they were ridden both affect the expected life of the bearing and can vary significantly. If the bearings begin to feel excessively rough or notchy or the inner race begins to show a high degree of play then it may be time to swap them out.
+
Where should I buy replacement bearings? Standard and ceramic bearings can be purchased right here on our site!
+
How is this product shipped? We offer FREE SHIPPING (within the USA) on this product via USPS Priority Mail unless shipped with other items.

Can I ship to a different address from my billing address? Unfortunately, No. For security reasons Project 321 will only ship to the billing address or address associated with the PayPal account used to purchase the item. PayPal does allow the addition of multiple addresses on an account.

**IMPORTANT!!! Due to a large drive side flange spacing our hubs are ONLY COMPATIBLE WITH 51T MICROSPLINE CASSETTES. This feature of our hubs is designed to maximize drive side bracing angle and rear wheel lateral stiffness. This has been a feature of our hub design since before Microspline was released. Please note that when purchasing a hub set with Microspline driver or upgrading to Microspline driver on an existing hub set youwill be limited to 51t only. Thank you!
