Most golfers do not re-grip as often as they should. I still see people playing with the same grips that were on their clubs when they were purchased 5, 10, 20 and 30 years ago. While this may save them some money, it does not save them strokes. The golf grip is the only part of the club that you touch.
If it doesn’t feel good, becomes hard or slick or worn, it will affect your performance. If the pros are changing their grips on a regular basis, then everyone should as well. As a general rule, if you play or practice once a week, then you should change your grips once a year or season, twice a week, then they should be changed twice a year/ season, etc.
Some pros change their grips every week for that new grip feel. Some grips wear out faster than others and should be replaced very often. That is not the case with the C-Thru Grip.
MATERIAL AND PRODUCTION
C Thru golf club grips are made of a proprietary blend of TPR (thermal plastic elastomers). The material used is called Vulcathene. The material is non-porous and will not absorb water or perspiration. C Thru golf club grips will NOT get hard and brittle over time like other grips. It will NOT get slick like other grips. C Thru golf club grips will remain tacky and each time it is cleaned with a wet towel and dried, it will feel as it did when first installed. Of course the C Thru golf grip will wear and will slightly discolor (yellow) over time, but the image will still be visible through the grip.
C Thru golf club grips are made by the injection molding process. The cap is made with a harder blend of the same material and is attached in the molding process. Most other grips are made by compression molding, thermally bonding two halves of the grip together and attaching the grip cap. Some of these grips are then buffed (sanded) to remove excess material for aesthetic reasons. This process leads to inconsistencies in weight and size. C Thru golf club grips are made with a much tighter tolerance level.
SIZING
Golf grips are grouped by size. This is done for a few reasons. Ideally, you would like all of your golf clubs to feel the same. The shaft manufacturers use different size shafts. This is due to the playing characteristics that each shaft is designed to achieve.,/p>
Core sizes are numbers used to determine the inside diameter of the grip. The outside diameter of the grip when installed is directly related to the core sizes of the various grips. Inside of most grips are a series of letters and numbers, M for men’s, L for ladies and: 50,56,58,60,62 that designates core size in 1/100ths of an inch. These numbers relate to the core size of the grip. The higher this number, the thinner the walls of the grip, and the lighter the overall weight of the grip. The sizing may also have the letter R because some grips are round and some are ribbed. Some manufacturers designate a round grip with the letter R at the end of the coding, others use the R for ribbed. The ribbed grip has a flat spot inside the back portion of the grip.
Shafts come in various sizes measured in 1/100ths of an inch. Most golf shafts today are .600” or as we refer to them, 60’s. When the shafts vary in size, the grips need to be adjusted as well.
There is a “standard” size golf grip within the industry. It is measured 2” from the grip cap, or top, of the grip. This measurement is .910”. Putting an M58 grip on a .580” shaft will create a “standard” grip size. Putting an M60 grip on a .600” shaft will also create a “standard” grip size. Putting the same M58 grip on a .600” shaft will result in a slightly oversized grip (+1/64”). This seems to be the trend now with almost every manufacturer using this combination. The industry does NOT have any rules and regulations governing these measurements. This information is important because all grip manufacturers do NOT use the same “standard” of sizing, which is why some grips feel different than others
Now the fun begins. We have been brainwashed by the manufacturers to disregard the bottom portion of the grip. Many years ago, when C Thru Golf Grips first began doing club repair, they were just as concerned with the bottom portion of the grip when sizing and installing grips. The reason being is that the shafts all seemed to vary in size, due to the steps or tapering, as it reached the bottom of the grip. This is why C Thru golf grips produce a less tapered grip as well as a normal tapered grip. There are other manufacturers that are now producing a less tapered grip as well. The reason being that there is an optimum size for your bottom hand. Once you determine this, then the final size can be attained by knowing how much, and where, to place some build-up tape. This is a subject that would require some very good measuring tools and a long lecture, which we and C Thru Golf Grips will not bore you with.
