Which type of Alum frame: 6061 or 7005

Wheels of Happiness

4.07.2021





You often seen the grade of Alum used in bikes:   6061 or 7005,  The other MTB is marked 7005?  What does the alum grade mean?

The alloys in the 6061 series are:

      Magnesium - 0.8 - 1.2%
      Silicon           0.4 - 0.6%
      Copper         0.15 -0.4
      Iron               up to 0.7

7005 on the other hand contains:

     Zinc -            4.5%
     Magnesium   1.4%

Which one is better?  It is 6061.  Not because the other number is higher does it mean it is better.  But 7005 is more durable...

Bulk of alum bikes are under the 6061 classification

Growing consciousness and awareness for beautiful, quality, lightweight bike frames and wheelsets

                                       The OEM disciples are all setting to spread the good
                                         news about OEM frame and wheel set so that
                                         more will enjoy beautiful bikes at affordable price




This post did a number of posts on his OEM bike project;  and pictures of his finished project. I brought this in our Bisikleta Iglesia today. With the  number of people touching the bike, making suggestions, or joking about riding the bike by mistake, and openly saying that the bike is nice and beautiful I could judge that a number are really aspiring to get one.   An OEM bike.  No less than 5 may be out of 20 who biked today would, if given the chance get one.

Same thing about the readers at the net and social media. I got inquiries about: supplier of the OEM bike frame, how much is the budget, where did I get the  Direct Mount brakes, I would  say about 2 dozens are ready to start an OEM carbon fiber bike project.  For 1/5th the cost, you could  have a super bike lightweight shod in high end group and wheel set.

             Say frameset     CF                         P35,000.00
             Wheelset           CF                          25,000.00
              Ultegra RS 8000                              30,000.00
                            Total                                  90,000.00

 An orig legit sourced (mas mahal tubo ng reseller)  would set you back by P400,000.00.   4x ang mahal and most of them goes to the profit of the trader.

Why prevent those who are PHP challenged to enjoy super bikes at limited budget. Yong mayayaman ayaw ata.  Privileged sila ... kaya nilalait OEM at replica.   I tell you they perform just the same.  I have an orig carbon frame/bike and this OEM. Mas magaan at mas pleasant iride ang OEM...Mas guwapo at mas Oh ahh

How to make your bike lighter; light is might

Wheels of Happiness

Rizal, Philippines  | December 4, 2013

From Grimper Hereux

From wiki how

As we biked last Sunday VM told me about a You Tube video that adding merely a water bottle in a bike added 20 watts to a bike without adding speed or incline.  Conclusion:  light is might.  A heavy bike requires more power.

What are the ways to reduce weight:



1.  Buy lighter, albeit lighter frames like carbon fiber.

2.  Buy lighter chain ring set, and pedals

3.  Buy lighter wheel and wheel set tires  These will set you back by  30 to 50t and will save you about 2 lbs.  Your 19 lbs bike now becomes l7 lbs.  That is a lot of weight loss

4.  Remove all unneccessary accessories that add weight
