Head pt57 question

This was probably asked before but I can not find an answer in the search.

Most people put PT630/280/57A in the same sentence, is this accurate? I have read the 630 is flexier/lighter than the 280, though, they are both from the same mold as the 57A. So, between the 630 and 280, which one is really the pT57A? :confused:

thanks.

PT57A is an engineering Mold code, not the layup.
Therefore, the mold is the same on all three. However, usually, the PT57A suppose to mean the Pro stock (lighter, customizable) version...

It's the same mold. Same materials, same dimensions between pro and retail models, except that pro models are hairpins only, meaning no handle and not cut to 27". Hairpins are shipped to placed like Priority 1 to cut them to 27", add custom pallet, custom grip, and then weight it out to the specs of the pros.

Consider that most pro stock frames are customized to the point where 10 to 20 grams of silicone are added to the handle, and 10 to 30 grams of lead are added to the hoop to any given pro stock frame (by customizing company). Therefore the hairpin has to be light weight.

The final static weight of the average pro's frame, while on court, is less than 350 grams, with a swing weight of 365 or higher. You can't get to those numbers without significantly light weight stock frame.

I have a couple of retail, 20+ year old Pro Tour 630s. With strings and overgrip they weigh 370 grams and have a swing weight of 360. That's too heavy for any modern pro. Therefore, hairpins come out of the factory considerably lighter.

but still same specs, same dimensions, constant beam, materials, etc.

Really? That sounds wrong... They are normally bellow 350g and around 330 SW.
Maybe they came to you customized?

doc and anubis, thanks for inputs, but your theories are different. doc saying it is only the mold are the same, which I agree, 630/280 even have 57A printed on the hairpin under the pallets. anubis, I have doubts about your theory. People have reported here in the past, that the hairpin of 630 is lighter/flexier than the 280 hairpin. That is why I was asking in the first place, which one (which hairpin) matches the current PT57A hairpin flowing around in the market.

I've completely rebuilt both of my 630s. New grips, butt caps, CAP grommets. I've been through every inch of those frames and they have no additional weight added to them.

The 630 and the 280 is the exact same stick. Same flex, same everything.

Now, there are different kinds of pt57s, however. Same materials, dimensions and specs, but some pt57s have different flexes, depending on which pro its for. I don't know which ones are stiffer than the other ones, but for instance I know the flex of the 57a is different than the 57e.

Also, some 57s have different drill patterns.

Sometimes they have different variations in weight. Some are SL, L, LM and so forth

I am not sure about your theory but I disagree.

There is the Austria 280 that is the same materials as Euro (Austrian) 630. However, the TREK font 630 feels totally different from the other versions. The composition may be the same, the amount of materials and layup not.
The Chinese 280 does not even have the same materials.

The Pro stock, PT57A with PJs are the same materials, but totally different amounts making them considerably lighter in the hairpin to hairpin comparison. When you add silicone and lead to the Pro stock, you completely alter the feel and vibrations, making it a different racket from the retail 280/630

Having played with a PT280, PT630, PT57E, and PT57A with the same string setup and weighting. I still play with PT630s. I can definitely say that they are different racquets. All in the same "family" but different from each other.

No, that is incorrect. vsbabolat confirmed in that thread that they are the same stick.
vsb is highly respected and I am his follower too, read many of his posts. but I do not remember he said 630=280, but he did say they share same mold also the original Radical 630 and Radical TT. and he confirmed many of these variations play quite similar.

People, you are fussing way too much about this. Not even 2 frames of the same model fell completely the same. I have 3 O3 Whites and one pro stock, they all differ slightly. I had 4 POGs 4-stripe, they also all felt slightly different.

To the best of my knowledge, 630 is Euro branding, while 280 North American, otherwise the same frame. They are all from the PT57 mold, while the pro stock is a lighter hairpin.

I like this simple explanation. Except, I'd use the word "similar" in place of the "same"
