Are 10 and 11 speed derailleurs the same?

Are 10 and 11 speed derailleurs the same?

the 10 speed and 11 speed derailleurs are interchangeable as far as the shifters go, the difference is that a 10 speed derailleur doesn’t like a cassette cog much bigger than the 36t it was designed for, where the 11 speed derailleurs are designed for 40 and 42t cogs, and seem to be able to handle bigger.

Can you use a 12 speed derailleur on 10 speed cassette?

-10 speed shifter sets your throw to match the rear cassette. -chains have the same outer dimension, the 12 speed derailleur would have narrower cogs than what required for a 10 speed. -As long as you can set the high/low limits on the derailleur to keep it on the cassette it should be fine.

Can I use a 11 speed cassette with a 10 speed derailleur?

It’s up to the rider to move the shifter to a position that would trigger and maintain a shift. If you have a friction shifter, you will be able to combine a 10-speed derailleur with an 11-speed cassette as long as the derailleur has the capacity to cover the entire cassette.

Can I use an 11 speed shifter with a 10 speed derailleur?

No, that will not work. The shifts will not line up across the entire range, because an 11-speed cassette is not just a 10-speed cassette with an extra cog stuck on at the same spacing.

Which Shimano derailleurs have a clutch?

Only Shimano offers clutched road rear derailleurs for two-chainring transmissions, though — the Ultegra RD-RX800 for mechanical shifters, and the the Ultegra RD-RX805 for Di2 electronic systems — while SRAM’s clutched models are limited to single-ring drivetrains.

Can I upgrade my Shimano 10 speed to 11 speed?

Luckily, many common and not-so-common wheelsets, as long as they’re at least 10-speed, can be upgraded to 11-speed by purchasing a new cassette body. The body is the part that attaches to the center of the hub and drives the wheel and bike when you pedal.

Can I use a 10 speed derailleur on a 11 speed cassette?

10-speed rear derailleurs do not work accurately with 11-speed cassettes when coupled with index shifters. The only exception are SRAM’s 10-speed exact actuation road derailleurs which have the same rear shift ratio as SRAM’s 11-speed road (exact actuation) and 10-speed MTB (exact actuation) derailleurs.

How do I choose a derailleur?

When buying a new rear derailleur be sure to match it with your drivetrain ‘speed’. 10-speed drivetrains use narrower chains than 9-speed so you’ll need a mech to match. Most rear mechs are made of a polymer and alloy mix but you’ll find carbon fibre in top-end models to shave even more weight.
