Product Details

Overview & Technology

Wheels Manufacturing Front Cones (CN-R036) are precision-machined replacements engineered to Shimano Ultegra or higher quality standards. Each cone is finished on precision lathes and ground to tight tolerances so the bearing race seats and axle preload behave exactly as the original equipment intended. Manufactured from heat-treated, high-strength bearing steel and finished with precision threads and bearing surfaces, these cones deliver consistent contact geometry and low friction under load. The result is reliable, smooth-rolling hubs that resist premature wear even in the demanding, muddy conditions common to cyclocross racing and training.

Key Features & Construction

Precision fit: Machined to the same dimensional standards as Shimano Ultegra cones for exact interchangeability with compatible front hubs such as 400 CX, HB-RM50 and HB-RA50. Part number CN-R036 is produced to tight tolerances so bearings seat squarely and preload adjustments remain stable. Durable materials and finishing: These cones are made from heat-treated bearing steel with precision-ground bearing faces and rolled threads. That combination improves wear resistance, reduces vibration and maintains smooth bearing rotation over many service intervals.

Fit, Compatibility & Specs

Compatible models listed for this cone include 400 CX, mountain HB-RM50 and HB-RA50 front hubs. Manufacturer part #: CN-R036; Forest Bikes product number: 090093. Shipping package measures approximately 3" x 2" x 0.4" and weighs ~0.02 lb, making it a compact spare to stow in a toolbox or race kit. Check your hub code or existing cone markings to confirm match before ordering. If your hub uses a different cone variant (for example CN-R040 for RX-100 / Deore LX), select the matching part to avoid thread or bearing-face mismatches.

Who It's For

This cone is ideal for cyclocross racers, mechanics and commuter cyclists who need a reliable OEM-style replacement for front hub service. Its precision finish and hardened construction suit riders who expect frequent wet/muddy rides and want a durable component that keeps hubs running true between rebuilds. Wheelbuilders and home mechanics will appreciate the exact-fit nature of Wheels Manufacturing cones for consistent bearing preload and minimal fuss during rebuilds. If you’re maintaining Shimano-compatible hubs and want parts that meet or exceed original standards, this cone is a practical choice.

Frequently Asked Questions

Will this cone fit my hub?

Check your hub model and existing cone part number before ordering. CN-R036 is specified for 400 CX, HB-RM50 and HB-RA50 front hubs. If your hub listing or stamped cone matches one of these, CN-R036 will fit and function as an OEM-style replacement.

Are cones sold individually or as a pair?

Cones are typically sold individually — left or right — so you can replace only the worn side. This product listing indicates front cones (left/right); select the correct variant or quantity for your needs.

Do these cones include bearings or seals?

No. Cones are replacement bearing races only and do not include loose bearings, seals or dust caps. When servicing hubs we recommend replacing bearings and seals as needed and using fresh grease for best performance.

What material are these cones made from?

Wheels Manufacturing cones are produced from heat-treated bearing-grade steel with precision-ground bearing surfaces and finished threads. That construction improves wear resistance and delivers long service life under load.

How do I install and adjust these cones?

Install the cone onto the axle to seat the bearings, then set the hub preload by tightening until play is removed and rotation is smooth. Final micro-adjustment is done while the wheel is mounted to the bike. Use the correct cone wrench sizes to avoid damaging flats or threads.

Can I use this cone on the rear hub?

These cones are specified for front hub applications listed in the compatibility notes. Rear hubs often use different cone dimensions and thread lengths, so verify a rear-specific part number before attempting installation.

Buying Guide

When buying hub cones, match the exact part number or hub model — subtle differences in thread length, shoulder location and bearing-face diameter can make an otherwise similar cone incompatible. Use your hub’s service manual or the existing cone markings to identify the correct replacement. Consider replacing cones along with bearings and seals in a full hub service; new cones on old, pitted bearings will not restore ideal performance. Keep a spare cone in your toolkit if you race cyclocross or frequently ride in wet conditions — a quick cone swap can save a race day.
