Frames with known compatibility issues

Though the CinQo fits a variety of bicycles, there are certain models due to over-sized bottom bracket shells, that the CinQo does not fit.

  • Willier Cento Uno 2010 or later - (Any current or later model Willier with similar frame specifications to the Cento Uno)
  • Eddy Merckx EM5 & EM7: known issues with the Sram GXP - We successfully installed an FSA-SLK with the wave-washer on the drive side
  • Gary Fisher Carbon Road Cronos 2009 and 2010 models
  • Principia C24T Known issues around the BB86 shell with the FSA-SLK CinQo
  • Avanti Team Quantam: due to an oversized bottom bracket shell.

If you are aware of any other frames that do not work well, or have had issues with in the past, please contact us with the make, model and year of the frame.

What CinQo fits my bike?

Your bike's bottom bracket determines what CinQo Saturn powermeter will fit your bike. There are four main bottom bracket (crankset bearing) systems in use today and the bottom bracket shell on your frame will follow one of these standards.

1. Threaded (English/BSA and Italian)

The threaded bottom bracket has been around for many years and is the most common type. The width of the shell is 68mm (73mm on mountain bikes) and is threaded either English (1.37" x 24 TPI) or Italian (M36 x 24 TPI). Most bikes are English threaded unless it is an Italian bike (Colnago, Pinarello, etc.) in which case it is likely Italian threaded.

A number of bottom bracket bearing assemblies fit the threaded shell type including square taper, ISIS, Octalink and external cup. External cup bearings are currently the most popular (see the photo below). External cup designs include Shimano, FSA and others that have a 24mm crank spindle. SRAM's Giga-X-Pipe 'GXP' bottom bracket uses external cups but the bearings taper from 24mm on the drive side to 22mm on the non-drive side.

Regardless of the bottom bracket bearings you have now, it is easy and inexpensive to change to a different threaded bottom bracket type.

  • Rotor 3D cranks are compatible with Shimano bottom brackets. i.e. You can replace Shimano cranks with Rotor 3D and use the already installed bearings.

2. BB30, OSBB and PF30

The BB30 bottom bracket was developed by Cannondale and is becoming increasingly popular. It uses a 68mm wide shell and a 30mm diameter spindle, hence the name BB30. The shell itself is not threaded; instead the bearings press directly into the frame.

The most common BB30 bikes are Cannondale and Specialized - Specialized call it Oversized BB or OSBB - but other manufacturers also use this standard. OEM BB30 cranksets include Cannondale's Hollowgram SI and SL and the Specialized FACT Carbon cranks. A BB30 crankset will not fit on a bike with a threaded bottom bracket shell.

Press Fit 30 (PF30) is a SRAM-developed version of the BB30 system where the bearings are housed in press-in plastic cups, which are in turn pressed into the frame. This system facilitates looser manufacturing tolerances and promotes improved bearing life. BB30 and PF30 use the same cranks.

  • Specialized FACT carbon cranks cannot be purchased from Quarq.
    • Customers can ship their cranks in for installation, there is no associated cost to mounting the CinQo. Conversely customers can self-install the CinQo, provided they have a lockring removal tool.
  • Fitting SRAM S975 BB30 cranks in a Specialized OSBB requires spacers found in the SRAM BB30 Assembly Kit.

3. Integrated Bottom Bracket - BB86 and BB90

The integrated bottom bracket standard uses a 24mm spindle with press-in bearings. Basically, the bottom bracket bearings from an external cup system are pressed directly into the frame, eliminating the cups and threads. This system can use cranks designed for external, threaded bearing cups.

Variations on this system were developed independently at Scott, Trek and others. There is not a common name beyond "integrated bottom bracket" but the overall shell width is typically 86mm or 90mm wide so the terms BB86 and BB90 have been popularized.

Bikes with BB86 and BB90 include high end carbon models from Trek, Scott, Giant and others.

  • For BB90, FSA SL-K Light must use the "BB adapter kit A - Trek Madone Carbon" ceramic bearing kit. Steel bearings cannot be used.

BB86/BB90

4. BBright

BBright is a bottom bracket standard developed by Cervelo that uses a 30mm axle and press-in bearings, but the left side bearing is moved out by 11mm to allow for wider frame tubes. This promotes increased stiffness. Some newer Cervelo frames use BBright. More information on BBright can be found at bbright.net.

5. BB386

According to the standard, BB30 or PressFit BB30 cranksets should work with the open-sourced bottom bracket standard. At this time we do not have any known confirmation that the Sram S975 BB30 or GXP CinQO's would fit on frames with BB386. The issue would be more to the over-sized nature of the shell, rather than the bearing or spindle diameter of the crank. As we get more information on the standard, or customers who have used bikes with BB386 we will update our information.
