The Ultra 100 and the Clash 100 are two of Wilson’s best selling tennis rackets and it is easy to see why as they both offer a great balance of power, control, and spin for beginner to intermediate tennis players.
The Wilson Ultra 100 (or “U100”) is in its fourth version (v4) whereas the Clash 100 (or “C100”) is in its second version (v2).
Wilson released Version 4 of the U100 in September 2022 while Version 3 of the C100 has no confirmed release date.

Both rackets share a lot of similarities including both having a 100in head size, a racket length of 27in, and a 16 x 19 string pattern.
In terms of weight, the U100 V4 has a slightly higher strung weight (318g vs 312g) and a heavier swing weight (317g vs 313g) but you won’t feel a huge difference in terms of weight when you are swinging these two tennis rackets.
The C100 (7 pts HL) is more headlight than the U100 (4 pts HL) so the C100 will be slightly more maneuverable when you are at the net.
In terms of stiffness rating, the U100 has a relatively high stiffness rating of 70 so it would not be ideal for anyone who has suffered from tennis elbow in the past.
In contrast, the C100 (57) has a super low stiffness rating for a frame of its type so it would be a very good choice for anyone looking for an arm friendly frame.
Recommendations
If you are unsure about whether you should buy the U100 or the C100, then I have listed some of my recommendations below based on some typical tennis player types.
As always, I would recommend that you take advantage of one of the demo programs available online so that you can properly demo each racket before you commit to buying either racket.
Beginners
Although there isn’t a huge difference in terms of racket specs between the two rackets, I definitely feel like the Wilson Clash 100 would be better suited for beginners as it has a slightly better balance of power, spin, and control than the Wilson Ultra 100.
Intermediates
Both of these rackets would suit most Intermediate Players but if you pushed me to pick one over the other, I would go with the C100 as I love the feel of the clash line of rackets and the arm friendly features of the racket will save you a lot of pain down the line.
Advanced Players
I think most advanced players will want a slightly heavier and more control-oriented racket than either of these two rackets e.g. Wilson Clash 98 or Wilson Pro Staff 97.
One Handed Backhand Players
I wouldn’t recommend either of these two rackets for a one-handed backhand player as neither has the level of control needed to hit an effective one handed backhand.
You can check out our guide on the Best Tennis Rackets for One Handed Backhands for our recommendations.
Players with Tennis Elbow
If you want an elbow-friendly tennis racket that will help with your tennis elbow then the C100 is hands down the best racket to go for as its stiffness rating is considerably lower than the U100.
