Wilson Ultra 99 Pro V5

The Ultra for people who meet the ball early and mean it.

A Steam-derived power frame with a rare 16x18 pattern, serious stability, and very little patience for late preparation.

THE ULTRA THAT EXPECTS YOU ON TIME

THE PARK TENNIS TAKE

The useful truth, in plain English.

The useful truth, in plain English.

Original editorial judgment · evidence below

Some racquets are happy to improvise. The Ultra 99 Pro would like to see the agenda. At a measured swingweight around 330, it is not especially interested in the forehand you began after the bounce. Get there early, set the racquet, and the old Steam 99 idea brings a very current amount of power and spin through a rare 16x18 stringbed. That pattern also makes strings part of the conversation, not an afterthought. This is the Ultra for the player who wants the line's punch with more weight behind the decision. It is not the Ultra for saving a late swing. It is the Ultra for making an early one count.

BEST FOR

Strong intermediates and advanced players with early preparation, full swings, and an appetite for Ultra power with more mass, stability, spin, and connection.

SKIP IF

You are frequently late, want a quick lightweight frame, prefer a soft muted response, or do not want string choice and restringing cadence to matter very much.

BEFORE YOU BUY

Ultra is the lineup. V5 is the generation. This page is the Ultra 99 Pro: 99 square inches, 305 grams unstrung, a rare 16x18 pattern, and model WR178711U. It is not the 100, 100L, 100UL, or the previous thin-beam Ultra Pro.

From the baseline

From the baseline

The 99 Pro carries more mass through the ball than the Ultra 100 and uses a rare 16x18 bed for lift and spin. Published playtests consistently describe a solid, penetrating response. The condition is timing: the racquet rewards preparation more than improvisation.

On serve

On serve

Mass, firm geometry, and the open pattern give the serve section real intent. Published testers found pace, kick, and slice available, but the racquet's swingweight asks the shoulder and preparation to stay involved deep into the session.

Against pace, the 99 Pro behaves like a wall when it reaches contact on time. Blocks, chips, and firm volleys benefit from the stability. Rushed returns reveal the other side of the same swingweight.

When contact wanders

The 99-inch head is not tiny, and the open bed adds useful forgiveness. The firm frame still reports off-center contact honestly. The racquet will help with stability. It will not invent early preparation retroactively.

Wilson lists a head-light unstrung balance. Measured strung samples land around 3 points head light with swingweight roughly 327 to 331, which explains the planted response and slower rescue swings.

THE LIMIT

The name says Pro, and the timing requirement agrees.

The name says Pro, and the timing requirement agrees.

Measured samples vary slightly, and playtesters disagree on exactly how much spin the 16x18 creates. They agree more strongly that the frame is firm, planted, string-sensitive, and less forgiving of late preparation than the Ultra 100.

Do you want the Ultra's power with more authority, or do you want the Ultra to make life easier?

Do you want the Ultra's power with more authority, or do you want the Ultra to make life easier?

Choose the 99 Pro when you already bring preparation and racquet-head speed. Choose the standard 100 when you want more of the family's help without carrying a measured swingweight around 330.
