Campagnolo Record Bottom Bracket:
  • Three, sealed cartridge style, bearings; two on the chain ring side and one on the non-drive side.
  • Campagnolo's lightest bottom bracket; weighs just 190 grams.
  • 17 mm, hollow cro-moly steel 102 mm spindle fits 8, 9 and 10 speed, Campy Record and Chorus two ring cranks, from 1995 to present.
  • Spindle mid-section is oversized to increase stiffness and reduce weight.
  • Unique taper is not interchangeable with Shimano.
  • Removable cups are machined from 7000 series aluminum alloy and are easily replaceable.
  • Comes with British (1.37 inches x 24 threads per inch) or larger diameter Italian cups (36 mm x 24 threads per inch). Spindles are identical and always 102 mm long.
  • Cups are lightly coated with thread lock and should be installed in a dry, clean bottom bracket shell. Do NOT grease or lubricate the threads.
  • We suggest using a Park Torque Wrench, for the most accurate installation. Campagnolo recommends tightening the cups to 70 Newton Meters (N.m) or 51.66 foot pounds.
  • Easily installs with a Campy or Park bottom bracket tool which also fits all Campy cassette lockrings. Any 1 inch ( 25.4mm ) socket will fit over the Park BBT-5 tool and allow you to use a torque wrench. Tools are listed below.
  • A carbon fiber cover further reduces weight and adds a touch of elegance to this beautifully crafted bottom bracket.
  • Made in Italy by Campagnolo and backed with a three year warranty.

Bottom Bracket width, diameter and threading

BB Graphic

Road bottom brackets generally are available with either British or Italian threads.
British is more popular in the US and is widely called English threading. British threads measure 1.37 inches x 24 threads per inch.
The frame, bottom bracket shell diameter of an English threaded bottom bracket (C) , is 1.37 inches (34.8 mm).
The length, distance from one cup face to the other (B) , of a road frame bottom bracket shell that is English threaded is 68 mm.
Road frames also come with Italian threaded bottom bracket shells. Italian threads measure 36 mm x 24 threads per inch.
An Italian threaded bottom bracket shell is 36 mm wide (C ) and 70 mm in length(B ). A British threaded cup will slide into an Italian shell without catching any threads. An Italian cup is too tall to fit into a British threaded bottom bracket shell.
The length (A) of your bottom bracket spindle must be matched in length and taper to the crank arm it was designed for.

Mountain bikes almost always come with English threaded shells. The exact thread measurement is the same as road bikes, 1.37 inches x 24 threads per inch. However, mountain bikes come with two different bottom bracket shell lengths; 68 or 73 mm. 68 mm is the most popular but 73 mm is catching on. Both often require different bottom brackets even though spindle length and cup threading is the same.

Bottom Bracket Compatibility - length and tapers

All cranks must be matched with a specific length bottom bracket spindle. Triple cranks or frames with oversize seat tubes require slightly longer bottom bracket spindles.
Shimano and almost every major bottom bracket maker have traditionally used the same spindle end cross section of 12.9 mm and two degree taper. Campagnolo uses the same two degree taper but has a smaller starting cross section of 12.7 mm.
A Shimano crank arm will bottom out on Campagnolo spindle. A Campagnolo crank arm will not draw far enough onto a Shimano spindle.
Phil Wood now produces both Campagnolo and Shimano taper bottom brackets in a wide variety of lengths. Phil bottom brackets are exceptionally well made and usually last for 30,000 miles without maintenance.
