Condensed Answer: Chainrings are less "pretentious" when it comes to chain size than cassettes. A 12-speed chainring can operate with a 10-speed chain if the rest of the drivetrain is…
Condensed Answer: 10-speed chains are slightly wider than 11-speed models. Consequently, the outer plates of the chain could come in contact with the cogs surrounding the sprocket currently in use.…
Short answer: A 9-speed Shimano or SRAM cassette can be installed on a 9-speed Shimano or SRAM hub right away. A 9-speed Campagnolo cassette cannot be installed on an 8-speed…
The factors that determine whether a 9-speed derailleur will be compatible with an 11-speed cassette are: The derailleur's rear shift ratio. The derailleur's total capacity. Understanding Rear Shift Ratios Modern…
General Information Cassette width: It's logical to expect a cassette with fewer gears (e.g., 10-speed) to be narrower than a cassette with more gears (e.g., 11-speed), but this isn't the…
Two factors determine whether an 11-speed derailleur is compatible with a 12-speed cassette and shifter: The derailleur rear shift ratio The derailleur's total capacity Understanding Derailleur Rear Shift Ratio Apart…
Condensed Answer: A 10-speed chain can technically work with an 8-speed cassette, but the dimensions of the chain are not ideal. Both the inner and the outer width of the…
Condensed Answer: An 11-speed chain is narrower than a 9-speed chain and can therefore work with a 9-speed cassette. The combination, however, makes little financial sense because 11-speed components are…
Condensed Answer: A 12-speed chain can operate with a 10-speed cassette. The only exception are Shimano's new 12-speed chains. Those don't mix well with 10-speed chainrings. Understanding Chain Width A…
If a rim has a 25mm internal width, then it's too wide for a 28mm tire by conventional standards. If the 25mm measurement refers to the external/total width of the…
