Review: Adidas Adipower Pro strings Author: Cheung Preamble This year we have seen the introduction of the Adidas range of racquets and footwear. Added to the range are a new range of strings. The market leader in strings is, of course, Yonex starting with BG-65 in the 80's. Lately, we have seen Ashaway build up a bigger presence with their Zymax range. Can Adidas provide a viable alternative with a range of six strings? Let's first look at some of the technical details. We see that the strings have a core made up of high polymer multilfilaments surrounded by a coating of nylon resin. There is are two discrepancies in the marketing literature. The words on the diagram in the brochure say "high polymer nylon multifilament 1pc" implying one single thread when there are multiple filaments in the core. Secondly, we see the word 'high' and 'hi' both on the same page. Do they have the same meaning or do they refer to something different? Perhaps I am being overtly fussy but then again, there are some people on badmintoncentral forums that set very high standards! There is another outer layer of 'braided high polymer nylon monofilaments 48pcs". Again, the diagram is inconsistent with the description. A braid should have intertwining filaments, but this is definitely not shown in the cross-sectional diagram. What we are shown is a single layer of nylon filaments arranged in a slight spiral. I am left feeling puzzled - is it or isn't it supposed to be braided? Finally, the whole thing is covered with another layer of nylon resin. We are told this technology will 'keep the strings in a round shape and deliver greater repulsion and power'. The same design applies to all 6 strings in the range. Description adipower Pro The adipower Pro string comes in 10metre lengths or 200metre lengths and is of 0.66millimetre diameter. The review strings came from a standard stock supply in 10 metre length. It came in a white colour. The strings are quite clearly marked "ADIPOWER PRO MADE IN JAPAN". They do feel smooth on the surface when you run you fingers over the string. Strings were supplied, and the racquet strung by MBS at 27lbs tension on an electronic stringing machine. The racquet was a Yonex carbonex 20 classic which has been my standard racquet for many years. There was nearly a week from stringing the racquet to actual play. Assessment was solely with feather shuttles. Another issue we have seen with these strings is why does it have the same name as the racquets? Again, it's a potential source of confusion for consumers and vendors. Imagine ordering some strings for about 7-9USD each and then getting a few racquets instead. It's only good if the racquets came at the price of the strings! OK, let's go back to the catalogue and look again. Oh, I notice the racquets are named as "adipower pro" and the strings are "adipower Pro" - the difference of a capital letter. Didn't I say badmintoncentral forums set very high standards? Power Having just recovered from Golfer's elbow, I am anxious to give this string a good whack (and test my arm in the process). Starting off with gentle smashes, the signs look good. There is a slight bounce and rebound of the shuttle off the strings. Before anybody starts asking what the heck is a gentle smash, I move on to smashes with a lot more power. I'd say the strings allow the player to produce a lot of power and rate them as very good. Sound Hitting your smashes gives a low pitched boom sound. Lower pitch compared to other 0.66millimetre strings on the market. Hard hitters will like it. Control Drives and smashes are very good but they do not always win you games. I moved to pulling the shuttle around the forecourt and midcourt areas; trying cross courts, half court dinks, soft pushes etc. Here we see the control aspect is not so strong. As mentioned before, the string surface is smooth. This causes me to be try and play shots with a higher margin of error. I would still rate it as good. Feel String feel is a difficult quality to describe. It reflects one's overall impression of the shuttle on the string bed when playing shots. Here again, I would rate the string as between good and very good. Tension holding The strings don't seem to be losing much tension. Remember that it took nearly a week for me to get on court to try out the strings. It is quite possible the strings had lost a bit of tension already. There is absolutely no problem with that so long as the tension still holds after that. Durability Examining the strings closely after 8-10 hours of strokes and smash practice, I see the strings seem to hold up quite well. It looks like the strings will stay for quite a while considering the thin string gauge. There is no notching nor fraying of the string, in part due the frictionless surface. Conclusion The adipower Pro string is definitely one of those strings you have to try out. It benefits from the thin 0.66mm gauge. It's got good durability. Compared with the other 0.66mm strings I use from Yonex, the characteristics are slightly different. There is not much to choose between the strings so it comes down to your own personal preference to play with it regularly. I would say there is a tendency for it to favour the power players rather than the control players.
