Who is making SRAM components.....?
SRAM was originally owned by SACH's. Not sure, but I think SR now owns
SRAM. Sachs automotive still makes motorcycle chains. So I would not be surprised if SACHS is still OEMing chains for SRAM.

Crappy shifting, bearings that constantly had to be repacked, headsets that required regular fiddling, heavy steel frames that fatigue cracked, weak brakes, cables that snapped regularly, flimsy tubular rims that dented and broke easily. |

SRAM acquired Sachs. And before the chains were Sachs they were Sedis. http://www.sedis.fr/en/sedis_group/history.htm http://www.bikepro.com/products/chains/sachs-sedis.html Also: http://www.fundinguniverse.com/compa...y-History.html http://velobase.com/ViewBrand.aspx?B...9fe6a27&From=T DR |

When Sachs was making components they were using Weinmann. Weinmann
looks as though they have been acquired and only the rims exist now. On Feb 20, 11:21*pm, Randall wrote: Who is making SRAM components.....? The brakes look at lot like the old Modolo SLK brakes. Modolo has been OEMing brakes for various companies over the years for Mavic. I would not surprised if Stronglight was making their cranks as well. Not certain if the Huret division is still making parts. I can't believe that *Sachs shut down the Maillard division. When Sachs acquired Maillard they were the number #1 hub manufacturer in the world. The Normandy hubs were standard on most of the bikes until the late 80's. Today the consumers have live with these junky Joytech hubs that are rough because the hub flanges are not parallel. |

Kinetic energy is not proportional to speed. I am aware of the implications of "Ek=1/2(mv^2)". v is dictating the kinetic energy changes in this model. I barely regret the oversimplification. Indeed, I understated the case for my claim: "road bikes have the potential to put far higher stress on their braking systems than wussy MTBers." (I do regret the awkward comparison of "road bikes" and "MTBers.") So, anyway, as your speed goes up, your kinetic energy goes up very rapidly, and that largely dictates the amount of energy your brake discs have to dissipate, so road bikes may need surprisingly big discs. |
