160mm Stainless Steel Disc Brake Rotor (6-Bolt)
Key Features
- High-Grade SUS410 Stainless Steel: Manufactured from premium heat-treated stainless steel for excellent anti-corrosion properties and high-strength durability under heavy braking.
- Advanced Heat Dissipation: Features a specialized "skeleton" or ventilated pattern that increases surface area to quickly dissipate heat, preventing "brake fade" on long descents.
- Universal 6-Bolt Mounting: Engineered with a standard 44mm bolt circle diameter (BCD), making it compatible with the vast majority of mountain bike and road bike disc hubs.
- Precision Ground Surface: The friction surface is double-sided ground to a mirror-like finish to ensure immediate pad engagement, reduced noise, and a shorter "bed-in" period.
- Lightweight Wave Design: The outer wave edge helps shed mud, water, and debris quickly while reducing the overall rotating mass of the wheel.

Compatibility & Fitment
This rotor is a universal component compatible with most modern disc-brake-equipped bicycles. Key fitment details include:
- Bicycle Types: Mountain Bikes (MTB), Road Bikes, BMX, Gravel Bikes, and Electric Bikes (E-Bikes).
- Hub Compatibility: Fits all standard 6-bolt hubs. (Note: Not compatible with Shimano "Centerlock" hubs without an adapter).
- Brake Systems: Compatible with both Mechanical (cable) and Hydraulic disc brake calipers.
- Pad Compatibility: Works with Resin (Organic), Semi-Metallic, and Sintered (Metal) brake pads.
When to Replace
- Minimum Thickness Reached: Most rotors have a "Min. TH" (often 1.5mm) stamped on them. If the rotor is thinner than this, it is at risk of structural failure.
- Warping or Wobble: The rotor is physically bent and rubs against the brake pads during every wheel rotation, causing a "pinging" sound.
- Deep Scoring: Visible deep grooves or "lips" on the friction surface caused by worn-out brake pads (metal-on-metal contact).
- Discoloration: A dark purple or blue "burnt" tint on the metal, indicating the rotor has been severely overheated and has lost its tempering.
- Persistent Squealing: If cleaning the rotor with alcohol doesn't stop the noise, the metal may be glazed or contaminated with oil.
Installation Tips
- Clean the Surface: Before installation, wipe the entire rotor with 70% or higher Isopropyl Alcohol to remove the factory protective oil film. Do not touch the friction surface with bare fingers after cleaning.
- Bolt Tightening Pattern: To prevent warping, tighten the 6 bolts in a "star" pattern (1-4-2-5-3-6). Do not tighten them in a circular sequence.
- Torque Specs: Most rotor bolts require a specific torque (typically 4–6 Nm). Over-tightening can strip the hub threads or snap the bolts.
- Thread Locker: Ensure the included bolts have pre-applied blue thread-locker (Loctite), or apply a small drop yourself to prevent the bolts from vibrating loose.
- Bed-In Procedure: After installation, perform 10–15 controlled stops from moderate speed to "marry" the brake pad material to the rotor surface for maximum stopping power.

Good watch
Color: Black
Needed a practical watch for everyday use and this fit the bill. Not too big, has a good sized watch face.

Nice looking, easy to read, comfortable silicone strap, hard to buckle.
Color: Black
This watch has all the features other Ironman watches have plus a 100 lap interval timer. The interval timer is possibly the reason this watch is slightly more expensive than the other IM variants with the same size and general appearance. I find this watch to be nicer looking when going out to dinner than the more common multi-colored IM watches, though most of the functions are available on the others.
My previous Ironman watch had a resin strap, which was somewhate stiff when putting it on. It was comfortable enough wearing on the river, but later in the day I sometimes took it off for comfort. This watch has a soft, stretchy, more comfortable silicone strap, that, sadly, is hard to buckle and tuck-in.

Longtime Ironman Wearer -- I Hate This Watch
Color: Black
I've worn the old Ironman 100 Lap Watch for Years
I would still be wearing those watches if the Indigo on them didn't consistently fail.
My main requisite is large, easy to read digital display, and the ability to turn the Indiglo on 20 seconds a day once or twice to see time in dark.
If I could have found a simple watch with a large display made by any other reputable manufacturer I would have bought it instead. I have truly come to dislike Timex because their Indiglo fails so consistently, on (5) different Ironman's I've owned. Doubt this one'll be any better, viewing it a disposable purchase after a year. Unsurprisingly, Timex is an American company, all marketing no quality, and yes I'm an American, looking at something Casio Seiko, Swiss or Japanese made. They get fundamentals right in terms of quality.
The band on this is redesigned. Grippier. Tougher to adjust or put on, but more apt to stay on and not slide once on. I'm used to the old band, don't love or hate this new one. I will usually take my watch off while typing for a long time, not as easy to do with this, not a dealbreaker, can see the sense in making a swimming and exercise watchband a bit tougher.
I hate the branding on this watch. Bright red Ironman logo on both ends of the band near the watch. Even worse is the Timex and Ironman words ATOP the glass on the watch. This means they throw shadows down onto the watch face below the glass. This effect gets even worse with the magnification underwater. Inexcusable design flaw, simply so some corporation can self-advertise its products. The combination of these two sets of branding make the watch look cheap, gaudy, and inappropriate for any remotely formal wearing. This would not have been the case if it was understated in color scheme. Without the two red marks on the band, and the absolutely moronic decision to place the branding on the watch glass, you have something understated you could get away wearing all the time. Not with the branding. There are also two lines running horizontally above and below the time. I hate these when I'm looking at it underwater. Haven't tried the lap functions yet, I usually open lake swim, maybe the lines help with that, but for my use I hate them.
I'm 6'4" tall, people complain the watch is big, it feels to me if anything a bit undersized or the proper size, others may find it big. I would rather have a slightly larger size with bigger numbers.
Biggest plus is time SUPER easy to read. I'd love to be able to turn date off and only have time display and nothing else in some mode. I don't need to check the date 6 times a day. Love to have mode where I press one button, upper left say, and date shows for five seconds or something.
Indiglo about the same as old big Ironman 100, excellent--when it doesn't break which it almost always does. I have many of these watches where the time still shows but Indiglo never works, Timex themselves admitted to me this is a known problem.
The rounder face, versus rectangular, better looks, but wonder if it is optimal way to make most readable.
I would pass on this watch. I have always liked Ironman watches, but the branding is so bad, glass especially, and the absymal quality of Timex Indiglo, are unacceptable.

Cool & functional
Color: Pink
Attractive watch. Simplistic, yet cannot understand everything without not having instructions. Watch did no come with instructions, which became hard to figure out all its functions.
