Campagnolo 9 Speed MK 2 Cassette Cogs

Heat treated steel cogs are carefully machined, nickel chrome plated and hand polished.
The smallest cog has a hardened chrome, satin silver finish for longer wear. This is the same heat treatment and finish that is now applied to all of the Record 10 speed steel cassette cogs.
Each cog has an indented ramp, called EXA Drive, to assist in up shifting. Tooth profiles are also custom configured to help with down shifting.
Campagnolo designates any 9 or 10 speed cassette that uses cogs bolted to alloy carriers as MK 2 cassettes. Non MK 2 cassettes are simply 8 or 9 individual cogs separated by resin spacers.
We do not have nor can we get titanium cogs for titanium Record 9 speed MK 2 cassettes.
MK 2 9 speed cassette cogs can last up to 7,000 miles if you keep them clean, well lubricated and use a Campagnolo chain.
For longest life and smoothest shifting we recommend using Le Tour Chain Lube on these premium cassettes.
Campagnolo 9 speed cassette cogs technical information:
Each cog is 1.75 mm thick. Campy uses 2.8 mm amber resin spacers and spaces their cogs 4.55 mm on center. That is to say that the distance from the center of one cog to the center of the adjoining cog, measured from the center of the first cog to the center of the second cog, is 4.55 mm. The inside diameter of each amber spacer is 35.4 mm. The largest five cogs on an MK 2 cassette are riveted together on two separate carriers to reduce weight and increase stifness.
These cassette cogs will fit all Campagnolo 9 and 10 speed hubs from 1997 to the present. You may mix them with Ultra Drive (UD) cogs.
Made in Italy by Campagnolo.

Branford Bike Online Catalog - Archival Edition
brought to you by the former owner of Branford Bike, Tim Brockett via his personal web site, TimsLife.Com

This is an archival edition of the Branford Bike web site from February 2006. Complete with product photos, prices, how to articles and technical specifications it is a treasure trove of accurate, detailed and historical information.

In July of 2006 Branford Bike was incinerated by a huge forest fire. No one was hurt but the inventory and buildings were completely destroyed. I witnessed the fire and stayed until the trees were burning in my driveway. At that point I hiked from Branford Bike, through the smoke and embers, down the mountain to my Jeep 3 miles away. I took photos and wrote about the harrowing experience so everyone could see what I saw. My insurance was generous and I later rebuilt my home and started another business selling books. Read the story here.

Branford Bike was a huge part of my life for over 30 years; June 1976 to July 2006. I enjoyed those years tremendously and Branford Bike was often a labor of love. I hope you enjoy browsing through the archival catalog. If your visit brings back pleasant memories please share them with me via e-mail at timbrockett@gmail.com .

If you find any printed Branford Bike catalogs, advertisments or flyers please scan them as a PDF and email. Or you may mail them via US Post to Tim Brockett, PO Box 1711, Emigrant, MT 59027. Eventually I will post them in a Memorabilia catalog section.

Many Thanks and Best Wishes,
Tim Brockett
