Bike Checks: New Build on a Trek Fuel!

We will be featuring bikes that are build at Tionghin from now and having a bike checks on the complete set up!

Bike Checks on a Trek Fuel!
The bike was brought to us for assembling as it had received a new custom paint job and decals on it. The owner do own a JayTheHill Hardtail bike in Titanium, Ht.Xc.Ti stands for Hardtail Cross Country Titanium. So these decals was brought over to the new custom Trek colour, smooth finishing in classic style on a 90s Trek Fuel!

We do provide Matt race shield protections on your bikes with additional cost on the labour charges too!

The Secret Life Of A Hayes V-series Rotor

We take a closer look at how a Hayes V-series rotor begins life as a massive roll of steel, and becomes the finished product that their new Prime brake system uses.

The Secret Life series lets you look beyond the packaging and flash to see what it takes to bring to life the products that we use.

  • The stainless steel is purchased in a large continuous roll; like toilet paper, but without the perforations or 2 ply thickness.
  • The stamping press straightens the strip through rollers, then stamps out the shape. It’s a progressive die, meaning the rotor geometry is created by stamping the part multiple times with various dies. One hit removes material in the center for the hub, one punches out the cooling holes in the rub area, one creates the ‘spokes’ in the center, etc. The last hit is the one that punches the rotor out of the strip. Like making cut-out cookies, the rotor goes on for further processing and the rest of the strip is recycled.


The Hayes V-series rotor in various stages of production. If you thought that making a rotor was a quick and simple process, you thought wrong.

  • Then the critical dimensions of the rotor are machined. Things like the mounting holes and the lobes that locate the hub.
  • After that the rotor is ED coated. The whole rotor is essentially painted black. This keeps the “as-stamped” surfaces (those created from the stamping process that do not get machined or ground afterwords) from oxidizing.
  • The stainless steel we use is called martensitic stainless steel. It has very high strength, is heat treatable and machinable, but does not have the best corrosion resistance, compared to other grades of stainless steel. The ground and machined surfaces of the rotor have a very smooth surface finish, almost mirror-like, which keeps oxidation (rust) to a minimum, but the rougher as-stamped surfaces will begin to show red rust over time if not protected as the high amounts of iron in the stainless begin to oxidize or rust.
  • The rotors are ground to the proper thickness and flatness. This removes the ED coating off the part, except for the as-stamped edges.


Two pieces become one when the steel braking surface is riveted to the aluminum carrier

  • Then the rub area of the rotor is heat treated to increase hardness and reduce the wear rate. The heat treat is a special, proprietary process that maintains the flatness of the rotor.
  • The rotors are then ready for use. Bicycles are of course lighter than most all other vehicles with disc brakes, but in the ultra weight conscious bike industry, the mass of the rotor is minimized creating extreme usage conditions that match or exceed the harshest motor racing environments.
  • Temperatures reach over 1000 deg F in the rub area, but remain much cooler at the hub. This creates a thermal stress as the rub area expands with heat, but the hub area doesn’t. The rotor needs to be able to allow this expansion, but still remain flat and return to its original form when cool. All this in addition to the brake torque loads.


After a lot of work, this is the finished product. This V-series floating rotor is used on the new Hayes Prime brakes and is available in 140, 160, 180, 203, 224 mm

A brake rotor is a simple looking part, but presents a formidable design challenge.

Shimano – Ice Technologies XTR Benchmark Test at Sicklines!

In order to test the limits of the Shimano XTR Ice-Tech rotors, Shimano solicited the help of Velotech to test the Saint as well as XTR brakes. See inside for the results from Shimano.

Shimano introduced a revolutionary cooling technology for disc brakes in 2010 named ICE TECHNOLOGIES. Since in any brake system there is a direct relation in between the generated kinetic energy (for brake power) and thermal energy (generated heat), Shimano has focused on the management of the system temperature. Lowering the temperature contributes to avoid negative effects on braking performance, as a result ICE TECHNOLOGIES brake systems have practically zero brake fading in normal usage, it increases the pad-durability up to 100% and reduces noise substantially.


XTR Trail brake with cooling fins and Ice Tech rotor

This technology basically consists of two elements. First of all, the rotors have a 3-layer sandwich structure of an aluminum core and two stainless steel outer layers; due to the higher heat dissipation of aluminum it reduces the rotor surface temperature with around 100 degrees. Secondly, the ICE TECHNOLOGIES brake pads that are recommended for trail riding feature aluminum cooling fins that can further improve the heat dissipation and reduce the brake-pad surface temperature by another 50 degrees.

The renowned German test institute “Velotech.de” has tested all SHIMANO XTR disc brakes in the previous weeks with striking results. They have tested the Cross-Country as well as the Trail version of the new XTR with different rotor-sizes and compared them to the famous SAINT brakes as well as with other high-end brands that are included in the usual magazine- tests regularly as well. You can check the details of the test results for the tested brake-models in the attached PDF’s of the original “Velotech.de” certificates and test reports at the right side of this web page.

The result in short:

  • All tested new SHIMANO XTR disc brake models/rotor sizes/pad combinations have exceeded Velotech’s firm disc brake standards, as well as the DIN EN 14766 and GS standards. See the attached reports for the detailed data.
  • The Ice-Tech brakes do withstand testing even under conditions that are 3 times as hard as required by DIN+.

  • Even if trying to test until failure of the brake Ice-Tech brakes are far ahead of the other brands and do withstand the test under 1050 Watt, while even the famous SAINT brake cannot do that (as a tip for SAINT users we recommend the usage of Ice-Tech rotors as these will improve the system performance a lot!!!).

Footnote:
* = marked brakes did complete the test without failure
** = the brake did fail in the 700W test already

The new XTR brakes work on a much lower temperature level than regular disc brake systems and do have practically no fading as you can see in the below chart

Shimano’s Conclusion – The Ice-Tech system contributes a lot to the lifetime of your system and the reliability and stability of your brake performance. Enjoy the ride!
