SANTA CRUZ RESERVE 99 TURBULENT AERO 700C RIM

The Reserve 99 TA carbon rim is the most extreme profile in Santa Cruz Reserve's road range: 99 mm deep, 38 mm wide externally and a claimed 645 g. It is the carbon time trial front rim for triathletes and TT specialists chasing the biggest aerodynamic advantage possible.

It is sold on its own, with no hub or spokes, and is intended for custom builds or for a mechanic to rebuild an existing wheel. Reserve uses it as the front of its 99|Disc set, paired with a rear disc wheel.

A 99 mm front rim, wide and stable

• With a 99 mm profile the rim fills much of the space between hub and tyre, leaving only a small portion of the spokes exposed to the air.
• The 38 mm external width, far more than the 30-31 mm of the 77|88 series, is designed to blend the airflow between tyre and rim and to make handling more predictable in a crosswind.
• 25 mm internal channel for stable tyre support and a well-supported air volume.
• Part of the Turbulent Aero family, developed by Reserve from real-world wind data.

Who the Reserve 99 TA is for

• Long-distance triathletes who want maximum speed in the aero position.
• Time triallists preparing for flat, fast courses.
• Athletes who also race on the track: Reserve lists the 99|Disc for time trials, triathlon and track racing.
• Riders pairing a very deep front rim with a rear disc wheel.

Building and compatibility

• 24 holes and a 433 mm ERD, essential for choosing spokes.
• ETRTO size 25-622, with recommended tyres from 28 to 32 mm.
• Designed for disc brakes, with no brake track.
• With a 99 mm profile you need suitable extra-long valves or extenders.
• A profile to use knowingly: in strong winds it calls for handling experience.

Why choose the Reserve 99 TA

• The deepest front rim in the Reserve road and TT range.
• Generous external width for clean airflow.
• Pairs with a rear disc wheel for a complete TT setup.
• Reserve lifetime warranty with no rider weight limit.
• A free base for your custom-built front wheel.

When races are won on average speed, the Santa Cruz Reserve 99 Turbulent Aero 700C rim is the component that makes the difference up front: give it to your mechanic, choose your hub and take your TT bike to the next level.
