RETURN COSTS & RESTOCKING FEE (ASSEMBLED ITEMS)
🚫 No Returns or Refunds on Assembled Shafts
Please note that all assembled shaft orders are final. Due to the custom nature of this process, we do not accept returns or offer refunds on any assembled shafts. Each order is built to your specifications, and once assembly begins, we are unable to restock or resell the components.
We encourage you to double-check all specs (flex, length, grip, adapter, etc.) before placing your order. If you need help confirming details, our team is happy to assist before you check out.
Returns can be made on non-personalized items and non-assembled items within the US, 60 days after you've received the original order. Items are only accepted on unopened and unused products. Items must be returned in the original packaging.
INTERNATIONAL RETURNS
We do not accept any international returns at this time.
At Grips4less, we strive to provide a smooth international shopping experience. To ensure clarity regarding shipping, duties, and returns, please review our policy below:
Duties, Taxes, and Import Fees
- International orders may be subject to duties, taxes, and import fees imposed by your country. These charges are the customer's responsibility and are determined by local customs authorities.
- If duties and taxes are not paid upon delivery, the carrier may be unable to complete the shipment and may return the package to us.
Refused or Unpaid Shipments
- If an international order is refused or the required duties/taxes remain unpaid, the carrier may return the package to us.
- In such cases, customers will be responsible for all shipping costs, including outbound and return shipping fees.
- Refunds for returned shipments will be issued minus all incurred shipping fees.
Lost or Delayed Shipments
- Once an international order has shipped, we are not responsible for delays caused by customs processing or other carrier-related issues.
- If a package is significantly delayed, we encourage customers to contact their local customs office or the carrier for more information.
By placing an international order (any order shipped outside the US), you acknowledge and agree to the terms outlined in this policy.

WHAT YOU NEED TO KNOW
The Aerotech SteelFiber i125cw is a taper-tip iron shaft with a graphite composite core inside a SteelFiber outer mesh. The "cw" means constant weight: every shaft in the set weighs 125 g, whatever iron it goes in. It has a 0.355" taper tip and is sold one shaft per iron (3-iron to wedge) in Stiff or X-Stiff.
Before you order: each shaft is made for one iron, so order one per club. True Temper makes the CW length specific, with no tip trimming. See How Tapered (0.355") Tip Shaft Lengths Work.
Who It's For
Good fit if you...
- Want a heavy 125 g iron shaft with a damped feel at impact
- Want help with height and spin: True Temper rates the CW high launch, high spin
- Want one weight through the whole set, 3-iron to wedge
- Have irons with a 0.355" taper-tip hosel
Not the right fit if you...
- Want something lighter: the SteelFiber i110cw is 110 g
- Need a Regular flex: True Temper lists the 125g CW in Stiff and X-Stiff only
- Have irons that take a 0.370" parallel tip
How It Plays
Damped feel. True Temper builds SteelFiber with a graphite composite core that damps vibration, then winds the SteelFiber mesh over it (more than 59 miles of fiber per shaft, by True Temper's count).
Same weight, every iron. The CW is made to one weight across the set, so your 3-iron shaft and your wedge shaft both weigh 125 g. Torque is 1.8° in Stiff; True Temper gives no torque for the 125 g X-Stiff.
High flight, high spin, moderate tempo. True Temper rates the CW high for trajectory and high for spin, with a moderate tempo. It suits a player who wants a higher flight and more spin from the irons, with a smooth, even transition rather than a hard, quick one.
Specifications
True Temper's figures for the flexes it lists.
| Series | Flex | Weight (g) | Torque (°) | Launch | Spin |
|---|---|---|---|---|---|
| SteelFiber i125cw | Stiff | 125 | 1.8 | High | High |
| SteelFiber i125cw | X-Stiff | 125 | Not published | High | High |
Material: graphite composite core, SteelFiber outer mesh | Tip: 0.355" taper, constant weight | Butt diameter: 0.600" | Raw length: 40" to 36.5" (True Temper lists no lengths for the X-Stiff) | Tempo: Moderate | Launch is True Temper's trajectory rating | Source: True Temper official Steelfiber CW (Taper) specs, checked October 2026
Will It Fit Your Irons?
This shaft is for irons with a 0.355" taper-tip hosel. Order one shaft for each iron you are reshafting and pick the iron number in the dropdown: the i125cw is made length specific for each iron at the same 125 g, so a 7-iron shaft is not meant to go in your 5-iron. True Temper says no tip trimming is needed; trim at the butt only to reach your playing length.
Not sure which tip your irons take, or how long each shaft should be? Read How Tapered (0.355") Tip Shaft Lengths Work, take the Iron Shaft Finder Quiz, or let us install them with our Retrofit Service.
