Both the front and rear boron/carbon axles are “dead” axle systems which means the axles do not rotate. Once in place the boron/ carbon axles not only support the vertical force from the wheels, but this axle design also contributes an additional benefit to enhance the lateral stiffness of your fork and frame.

Important to this structural augmentation to your frame is the requirement for a constant and significant longitudinal compression of your axle. Your axle/ hub system is designed for a moderate to high quick-release compression force. The end-caps and compression stack-up of the hub body, spacers and cassette (rear hub) will be free-rolling with minimal play along the axle when the quick-release compression force is moderate to high. It is important to note that a high quick-release force does not increase the thrust load on your hub bearings.

Each wheelset is specifically designed for Shimano or Campagnolo cassette. You cannot put a Shimano Cassette on a Campagnolo wheel and you cannot put a Campagnolo cassette on a Shimano wheel. The wheels are dished specifically for Shimano or Campagnolo.

Warning: Changing the cassette will void the warranty and will cause damage to the wheel. Additionally, the use of an improper cassette may pose risks of improper wheel operation giving rise to risks of substantial harm or injury to the rider and/or the rider's equipment.

Supported Quick Releases
Brands/ models listed have been tested and qualified by Lew Racing for use on Pro VT-1 and Pro VT-1C wheel sets.  Brands/ models not listed either have not been tested or do not provide sufficient compression force, strength or both.

Warning: Use of unsupported Quick Releases on these wheel sets may pose risks of substantial harm or injury to the
rider and/or the rider's equipment.

Bearings
Both front and rear hub shells are specifically designed for hybrid ceramic or 100% ceramic bearings. The hardness of a ceramic bearing which results in superior low friction performance also results in a bearing structure that is more brittle than a steel bearing. Ceramic bearings need to be pressed in with a minimal interference fit or they will crack. Lew Racing hub shells have been specifically developed for the ceramic bearings we specify.

Our full ceramics bearings are not sealed (seals result in high drag off-setting the benefit of the ceramic bearings). It is rare (but possible) that a hard impact can cause hairline fractures in ceramic bearings. Rough bearing motion may be an indication requiring inspection for cracks following a hard impact or crash if the bearing motion is not smooth.

Ceramic bearings will produce a very small amount of play in the hub mechanism. This is a trade off for the performance and weight loss that is gained by using ceramic bearings. Using the approved quick releases with maximum pressure will reduce this effect to a minimum. The boron axle is extremely stiff/rigid and will not bow under the high compression force of the quick release.

Tire Installation and Prep
The rims are sanded to prep the rim for gluing before shipping.  You may Scotch-brite™ the rim with green colored pads, but do not sand the tire channel before gluing the tire on the rim.

User should follow the specific instructions accompanying the tires you purchase and install.  We find many reasons to inflate your tires to our recommendations. 

(1) Do not assume all wheels are equal in stiffness or handling. 

(2) Pro VT-1 Wheels and rims perform best at the following pressures based upon a 20 – 22 mm wide tire. 

(3) Thinner tires will provide less stability and less protection to your wheel/ rim, while wider tires will provide improve stability and protection. 

(4) Clydesdale riders should only ride 22 mm tires or wider.  NEVER exceed tire manufacturer’s recommended tire pressure. 

(5) The manufacturer’s recommended tire pressure, especially for wider handmade tires such as Veloflex may in some cases be lower than our recommendation for a 20 - 22 mm wide tire. 

(6) Over inflation offers no performance benefits and carries detriments of increased shock, worse handling, reduced traction and increases the occurrence of flatting.

(7) Always test your tires before each ride by trying to push them off the rim and check to ensure that the base tape is has not separated from the tire.

Event: Road Race/ Criterium
Rider weight = 140 lb or less: 120 PSI Tire Pressure
Rider weight = 141-165 lbs: 121 -140 PSI Tire Pressure
Rider weight = 166- 185 lbs: 140 – 160 PSI Tire Pressure
Rider weight = 186- 215 lbs: 140 – 160 PSI Tire Pressure
Rider weight = 216 – 250 lbs: 150 – 180 PSI Tire Pressure

Event: Time Trial/ Triathlon
Rider weight = 140 lb or less: 140 - 160 PSI Tire Pressure
Rider weight = 141-165 lbs: 140 -180 PSI Tire Pressure
Rider weight = 166- 185 lbs: 160 – 180 PSI Tire Pressure
Rider weight = 186- 215 lbs: 160 – 180 PSI Tire Pressure
Rider weight = 216 – 250 lbs: 160 – 220 PSI Tire Pressure

Event: Track
Any Rider weight: 160 – 220 PSI Tire Pressure depending upon event

The Negative consequences of improper inflation pressures include:
(1) over inflation eliminates the principal shock absorber on a bicycle significantly impacting rider fatigue and equipment wear
(2) over inflation degrades the of handling by reducing the size of  the contact patch (increasing slip rates and side wash out)
(3) over inflation causes loss of traction (loss of rear wheel acceleration, and braking skids)
(4) over inflation increases the likelihood of tire puncture (less tire to road conformance, greater puncture load behind road hazards)
(5) over inflation increases the possibility of rapid catastrophic flat tires and accelerated tire wear

(6) under inflation may result in the tire slipping off of the rim and an immediate and sudden loss of control resulting in a crash
(7) under inflation may result in impact between the rim and road suddenly catastrophically failing the wheel or rim without notice

Warning: Warning: Improper installation, inflation, or maintenance of your tires may pose risks of substantial harm or injury to the rider, the rider's equipment, or riders around him/ her from a chain-reaction crash.

Rider Weight Limits
The lateral stiffness of a wheel also determines its match for a particular rider on a particular course. Lew Racing's carbon/boron composite wheel products are intended for use by persons who weigh less than or equal to the specific Approved Rider Weight limits set forth below in pounds or kilograms.

Weight Tubular Standard Set PRO VT-1
Both Front and Rear = 880 grams* (APPROVED RIDER WEIGHT < = 185lbs / 83.91kg)

Weight Tubular Clydesdale PRO VT-1C
Both Front and Rear = 1050 grams* (APPROVED RIDER WEIGHT < = 250lbs / 113.40)

Warning: Use of these particular products by persons/riders in excess of these specific weight limits voids the warranty and may pose risks of substantial harm or injury to the rider, the rider's equipment, or riders around him/ her from a chain- reaction crash.

Routine Inspection, Handling, and Storage of Composite Wheels

The all composite rim and spokes of the PRO VT-1 and PRO-VT 1C wheels need to be examined thoroughly before each ride for chips, nicks, cuts, scratches, cracks, or other damage to the wheels, rims, and spokes. In handling and maintaining your wheels, you should not use sharp tools on Lew Racing products or hammer or strike the wheel, rim, or spokes due to the risk of scratching, cutting, piercing, cracking, or damaging the composite material. You should not squeeze or bend the carbon/ boron spokes as that will result in damage to your wheel.

The wheels must not be stored or left for prolonged periods in direct sunlight or in areas in excess of 125 degrees Fahrenheit as improper storage and handling can cause degradation of the composite material. Cracks, damage, or material degradation compromises the strength, stiffness, and integrity of the wheels.

All of the above prohibited storage and handling mistreatments may damage your wheel, rim, spokes, or other wheel components and result in sudden and catastrophic wheel failure during use. In the event you detect any flaw in your Lew Racing product, you should promptly contact Lew Racing concerning an inspection of the wheel set and you should refrain from further use the wheel set in any capacity. Use of any wheel exhibiting such flaws as cracks, nicks, cuts, delamination, or any degradation of any wheel material may pose risks of substantial harm or injury to the rider and/or the rider's equipment. To extent rider uses any Lew Racing wheel set with knowledge of such flaws, or knowledge of misuse, abuse, tampering, or improper installation of any component on the wheel set or bicycle, the rider assumes the risk of harm or injury associated with such use.
