Great for Cross, Gravel Grinding, or any of the new road disc bikes. The 22 mm deep rim makes the ride compliant while the 24 mm wide rim also makes it perfect for the larger tires and lower tire pressures used on both road and off road riding. It's available with two hub options - a standard quick release version (in black, red, or silver) and a thru axle version (black only). Hub options are selected at checkout. The thru axle version uses interchangeble end caps with options for a 9,12, or 15mm front and a 10-135, 12-135, or a 12-142 rear. These can be swapped out later if you change your specificiation. As in all of my wheels, internal washers are used on the drive side rear spokes for added durability. In addition both the front and rear use an asym rim. The asymetrical rim moves the spoke bed off center toward the non dished side of the wheel. This helps equalize spoke tensions making for a stronger and more durable wheel. Dual sealed cartridge bearings are standard on all of my wheels. Cartridge bearings are great because they are supler smooth and easy to replace. The rear hub is 8.9.10 and 11 speed compatible. Fits a standard 6 bolt rotor.

Specifications

Size: 700C Clincher

Weight 1530 grams (without skewers or rim strips) weights can vary by about 50 grams a set due to rim, spoke, and hub weight tollerances.

Rim (for more information on rims and wheel building go to the rim page)

Rim Material 6066 Alloy - machined braking surfaces. Welded seam.

Drilling: 24 hole front and 24 hole rear

Rim Weight 445 grams

Rim Dimensions 22 mm high 24 mm wide

Rim ERD 593 mm

Spokes

Spokes if Sapim CX Ray 4.1 grams each bladed aero. Blade is 2.3 mm x 1 mm

Spokes if Sapim Laser 4.1 grams each Double butted 2.0-1.5-2.0

Spoke Length Front brake side: 2X 279

Spoke Length Front non brake side: 2X 283

Spoke Length Drive Side Rear: 2X 279

Spoke Length Non Drive Side Rear: 2X 280

Spoke Tension Front: 110-120 KGF (on a Park Tensiometer 13-14 for CX Ray and 18-19 for Laser

Spoke Tension Rear Drive Side: 150-155 KGF (on a Park Tensiometer 16 for CX Ray and 21 for Laser).

Spoke Tension Rear Non Drive Side: There is no spec for this because it is whatever it is to pull the rim to the center of the wheel. They will always be looser than the drive side spokes and often by quite bit.

Note: Wheels come with extra spokes and the exact length is indicated on the spoke package. We occasionally substiture when we are out of a particular length.

Spoke Prep

We use Loctite 242 on the non drive side spokes and on the front spokes during the building process (no lubricant). On the drive side rear spokes we use a lubricant to build (nothing special - just something slippery) and after the build put some Loctite 242 in to finish them off. The Loctite 242 will make the spokes harder to turn but will not sieze them.

Spoke Nipples

Front Nipples Alloy 14 gauge uses Park Black Spoke wrench

Rear Drive Side Nipples Brass 14 gauge uses Park Black Spoke wrench*

Rear Non Drive Side Nipples Alloy 14 gauge uses Park Black Spoke wrench

Note: We use brass nipples on the drive side rear because we have found that occasionally alloy nipples will crack. It adds about 11 grams to the wheel weight but we feel it is well worth it. Also, we build to extremely high tension and brass nipples are better able to handle the higher tensions.

Spoke Washers

Used internally on the drive side rear spokes. I have them custom made by Boker's in the US. They provide an extra layer or durability while adding almost no weight. Weigh less than 1 gram each.

Hub (for more information on hubs and servicing go to the hub page)

Front over lock nut dimension 100 mm

Front flange diameter brake side: 57 mm

Front flange brake side to center: 22 mm

Front flange diameter non brake side: 45 mm

Front flange non brake side to center: 35 mm

Rear Over Lock Nut dimension 135 mm

Rear Drive Side Flange Diameter: 53 mm

Rear Drive Side Center to Flange: 14 mm

Rear Non Drive Side Flange Diameter: 58 mm

Rear Drive Side Center to Flange: 34 mm

Campy Cassette body - 9,10, or 11 speed compatible

Shimano/Sram Cassette Body - 8,9,10,11 speed compatible

Cassette Body Bearings: 6902 (Two) Abec 5 sealed cartridge bearing with seals

Front Hub Weight 138 grams

Front Hub Bearings: 6802 (three) Abec 5 sealed cartridge bearing with seals

Rear Hub Weight 264 grams

Rear Hub Bearings: 6802 (both drive and non drive side) Abec 5 sealed cartridge bearing with seals

Note: On Shimano-Sram cassette bodies (they are one in the same) you will need a spacer if using it with a 9 speed cassette (which is included in the spoke package), for a 10 speed cassette (which is narrower than a 9 speed) you will need the included spacer and the one that came with your cassette. If your cassette doesn't have one you can get them at any bike shop. They are 1 mm wide.

Skewers

Skewers weight 46 grams front 50 grams rear.

Tire Recommendations

With the wider rims, you can use pretty much any tire width you want - from 19 mm all the way up to over 30 mm. I like 25 mm wide tires simply because they hold more air and are more comfortable. 23 mm tires are probably the fastest and are the most aerodynamic. As you get bigger tires, the limiting factor is the frame. Typically the tires will first rub on either the brakes (on the top of the tire) or with the rear tire hitting the seat tube. Most road bikes will fit up to 25 mm tires, a few bigger ones, and many won't even fit a 25 mm tire.

Tire Pressure Recommendations

With the wider rims you can generally run at least 10% less pressure than with a narrower rim because the system holds more air. Less pressure is better because you have a bigger tire patch and will roll over the bumps in the road instead of bounce over them (it's that sidewall flex that gives you better rolling resistance). Most people run too much pressure in their tires because they believe they are faster (and they feel faster at first). If the roads were perfectly flat that would be the case but they all have lots of bumps so lower pressures make sense. Generally speaking a 160 pound rider should be around 80-90 psi in the back tire and 75-85 in the front. If you have been running higher pressure you will immediately notice how much more comfortable the ride is and how much better the bike handles around corners.

Documentation

When you receive your wheels it will include a package with the extra spokes, skewers, a spacer (if a Shimano-Sram cassette is ordered) and some documents. The documents will list the builder and on alloy wheels a serial number (which is under the rim strip near the valve hole on both wheels). Also included is a spec sheet showing the type and length of spokes used and the spokes tensions for your wheels). There is also some maintenance info and whatever else I want to throw in there along with a copy of your invoice. We keep a record of your info here so you can contact us with either your invoice number (preferred), serial number (also OK), or your name and we can pull up your records.

Awesome wheels! 03/16/2021
By Mark Niswander
These wheels replaced the original set on my gravel bike. Each wheel is about a half pound lighter than the originals! That makes a BIG difference. I now have several hundred miles on them and they are great. They handle, climb, and descend very well. So far all of my riding has been on the roads but I intend to do some trail riding too. Hoping they will take me on a cross-country tour this year (but that's more up to me than the wheels).

And let's not forget, the superb service and communication John brings with any set of his wheels.
