Defiant Gen2 wheels - pushing fixed gear performance to the limits.

JUST 1.55kg.

We upgraded the Defiant Gen2 with special hand-built 50mm deep, 28mm wide rims. As with our Zenith Elite series, the rims weigh just 450g, down from the usual 520g.

Sapim CX Ray bladed aero spokes replace the Pillar 1423 spokes from the previous Defiant. With a thinner profile than the Pillar spokes, the CX Rays are lighter and stronger, helping you cut through the air with ease.

Following the great feedback that we got from the previous version, the Defiant Gen2 will sport Gran Compe Short Flange hubs as standard.

The Defiant Gen2 will retail at just SGD 1299. Choose from your choice of holographic, oil slick, DarkLight, or other standard colours at no extra charge.

  • 3-Year Limited Warranty

    All Defiant wheels are warranted against defects in materials and workmanship for a period of THREE (3) YEARS from the date of original retail purchase when installed properly and used for on-road riding. This warranty only applies to the original owner and is not transferable.


    Lifetime Stuff Happens Policy (original owners only)

    You ride hard, and sometimes, stuff happens. We've got your back.

    If your wheel experiences damage under any circumstance not covered by our warranty, the price of a replacement Ascent wheel is 25% off the current retail price. Please note that this does not include freight, taxes/VAT or the cost of other replacement parts.


    Worldwide Care Package

    For our customers worldwide, we will provide extra spokes and bearings with the set of wheels in order to minimize downtime in the unlikely event of a spoke or bearing failure. The wheels should be fixed by a certified bike mechanic.


    We encourage our global customers to resolve minor issues such as wheel truing locally if they are able to, as this minimizes downtime and transport risk.


    If you wish to ship the product back to us for a claim, please show us photos of the affected areas first. Often, the problem is relatively minor and can be rectified locally.


    Warranty Shipping (International Orders)

    The customer will send the package to Ascent Bikes, and bear the initial cost of shipment. We will examine the wheels upon receipt, and if the item is found to be covered under the Warranty, we will refund the cost of shipping, subject to the maximum amount paid during the initial purchase, and bear the cost of shipping the product back to the customer.


    If the damage or defect is not covered by Warranty, the customer will have to bear all shipping costs, including the return shipping cost back to the customer. The return shipping cost will be limited to the cost initially paid by the customer. We will only dispatch the wheels upon full receipt of the return shipping costs.


    Limitations on Warranty

    The warranty does not include damage caused by crashes, impact damage, transportation, abuse or if it is subjected to loads in excess of its design limits.


    The warranty does not apply if the product has been modified.


    The warranty does not apply if the serial numbers of the rims or hubs have been defaced or deliberately removed.


    This warranty does not apply to normal wear and tear. Wear and tear parts are subject to damage as a result of normal use, failure to service and/or riding or installation in conditions or applications other than recommended.


    The warranty does not apply if improper brake pads (for alloy rims) have been used, as those pads can damage the braking surface.
