frena, frena


rafa del club luis valtueña, informa sobre las pastillas de freno OBE para mtb


Pastillas de freno OBE: Buenas, bonitas ¡y BARATAS!
La marca de las pastillas es OBE (Original Brake Engineering) y las hacen para todo tipo de frenos y fabricantes.

Os cuento mi experiencia anterior con otras marcas y la comparo con las OBE. Por cierto, tengo unos frenos Avid Elixir CR

- Pastillas Avid Orgánicas: Frenan muy bien, son silenciosas pero me duran 3 meses. Cuestan 17,70 Euro el par en Chain Reaction
- Pastillas EBC Red: Frenan bien y son silenciosas y generan baja temperatura. Duran poco más de un mes ¡inaceptable!. Me costaron 13 Libras en UK
- Pastillas Kool Stop: Frenan bien, son más ruidosas, me han durado 3'5 meses. Creo que me costaron 18 Euro en Cosme
- Pastillas OBE semi-metallic: Frenan muy bien, hacen poco ruido y las llevo usando 2 meses y tienen muy poco desgaste. Me han costado 4,68 Euro comprando el pack de 4 pares. Envío gratis a España

¿Donde? pues en una web de UK http://www.discobrakes.com. El único punto negativo es que, como el envío lo hacen por correo ordinario (gratis), puedes tardar hasta dos-tres semanas en recibirlas. Pero si se piden antes de necesitarlas se acabó el problema

info about different disc brake pads
Disc Brake Pad Compounds

Many disc brake pads are available in different compounds

Semi-Metallic Compound

Also known as Compound S (Semi-Metallic)

Sem-metallic compound for good wear in all conditions. Medium density with consistent wet and dry performance and good grip.

Advantages: Cheap, Above average all around performance
Disadvantages: Grippier and longer lasting pads are available
Suitable For: Everything
Conclusion: Best Value

Superlight WorldCup Competition Alu Backed Pads use the medium compound.

Professional Grade Black Ceramic Compound

Also known as Compound C (Ceramic Pro)

These soft organic ceramic fiber disc brake pads are carbonized. The ceramic compound insulates the brake system from friction heat up to 400oC. The result is a very powerful, quiet pad with extremely low heat generation which all but eliminates the chances of brake fade.

# Details Upgrade on original fitted pads
# DIN 79100 Standard Approved
# Organic Compound contains no metal material
# Reduces damage to rotor
# Carbonized compound reduces brake fading
# Ceramic Fiber insulates brake system from friction heat
# Non-Asbestos


Advantages: Excellent grip, Low noise, Low heat, Consistent in all conditions
Disadvantages: Short life span unless rider is light on brakes
Suitable For: DH, Dry XC, Ti Rotors
Conclusion: Best Performance, Short Life

Metallic Sintered

Also known as Compound T (Sintered)

Superior power in all conditions
# Long wear pads, great for DH or XC
# Consistent braking power in the wet
# Almost unaffected by rain and snow
# Copper back plate


Advantages: Better performing and longer lasting than most pads
Disadvantages: More expensive than medium pads
Suitable For: XC, DH (low brake use), All weather conditions, Mud
Conclusion: Solid Pads and Best All Rounders

Red Ceramic Compound - Hard

Also known as Compound D (Ceramic Hard)

Harder than ordinary pads. This is the highest density, hardest, ceramic compound for performance and longer lifetime. These organic disc brake pads contain a high amount of ceramic fiber, which insulate the brake system from friction heat up to 400oC.

Advantages: Better performing and longer lasting than medium pads

# Details Upgrade on original fitted pads
# DIN 79100 Standard Approved
# Organic Compound contains no metal material
# Reduces damage to rotor
# Carbonized compound reduces brake fading
# Ceramic Fiber insulates brake system from friction heat
# Non-Asbestos


Advantages: Longer lasting than Black Ceramic pads
Disadvantages: More expensive than Black Ceramic pads and not as grippy
Suitable For: XC, DH (low brake use)
Conclusion: Advantages of a Ceramic Pad with Longer Life

Kevlar Compound

Also known as Compound VG (Kevlar)

Spring(s) Included

Contains Kevlar® brand fibre developed by DuPont.

Kevlar is a high strength synthetic fibre which dramatically improves the performance of these medium density pads and gives excellent braking power.

Advantages: Better performance than semi-metallic
Disadvantages: More expensive than semi-metallic and known to wear out faster in bad weather
Suitable For: XC, DH
Conclusion: Performance Advantages of Kevlar

Other Factors

Low Noise: The black ceramic compound C is thought to be virtually silent

DH: Black Ceramic pads are great for Downhill as the ceramic compound insulates the calliper pistons from heat build up so reducing the likelihood of brake fade.

Rotors: All of these compounds can be used with any rotor. Ceramic pads cause less damage to rotors than metallic compound pads. Titanium Rotors: We recommend black ceramic compound for titanium coated rotors, as it contains no metal, so will reduce damage to the rotor. The coating on titanium plated rotors is extremely thin (often just a few microns), so will ultimately wear off no matter what pad you use, but ceramic pads will prolong their life over pads containing metal.
