9 Speed Road STI + MTB Derailleur
4 min read
Asked by: Victoria Hills
Can you use MTB derailleur with road bike shifters?
Shimano derailleur compatibility
Most 8- and 9-speed Shimano mountain bike and road kit is inter-compatible because they both use the same cable pull ratio. This means that you can use an 8 -or 9-speed mountain bike derailleur with road shifters or vice versa.
Can I use STI shifters and MTB Rd?
As most of you know, neither SRAM nor Shimano allow their DoubleTap or STI road shifters to interface with their 12-speed MTB drivetrains. SRAM uses two different pull ratios on their mechanical groupsets.
Can I use STI on MTB?
Registered. The righthand (rear) Shimano 9 speed STI levers will work perfectly with Shimano rear derailleurs on 9 speed road or mtb cassettes.
Can you use MTB Rd to roadbike?
Mountain bikes are designed to work both on-road and off-road. Most times, it’s what type of trails can it handle. For instance, cross country bikes are for mild trails, dirt roads, and paved roads in normal use.
Can a 10-speed derailleur work on a 9-speed cassette?
Condensed Answer: 10-speed Shimano and SRAM MTB derailleurs have a different rear shift ratio than 9-speed derailleurs and cannot be effectively combined with a 9-speed shifter and cassette.
What is the difference between short cage and long cage derailleur?
Quote from video: So that cage has had to move right forward. Now the longer the cage the more of a difference in ratio between the smallest and biggest sprockets.
What does STI stand for Shimano?
Shimano Total Integration
When Shimano launched its STI (Shimano Total Integration) system, it did much more than just relocate and streamline the gear levers — it completely changed how people rode and raced bikes.
Are derailleurs universal?
No, bike derailleurs are not universal. A derailleur that works with one bike may not work with another bike based on factors such as the cage length. Check the difference between the smallest and largest cogs and also the chainring size to determine the derailleur compatibility.
What is the meaning of STI in bike?
Shimano Total Integration
Shimano Total Integration (STI) is a gearshift system designed by Shimano for racing bicycles. It combines the braking and gear shifting controls into the same component. This allows shifting gears without having to remove a hand from the bars, unlike previous down tube shifting systems.
Can a 10-speed derailleur work on a 8 speed cassette?
A 10-speed derailleur can work with an 8-speed cassette only in one situation – if it’s a road model designed by Shimano and not part of the Tiagra 4700 series. Why? Because the rear shift ratio of Shimano’s 10-speed road derailleurs is 1.7 and matches that of 8 and 9-speed Shimano derailleurs.
Will a 10-speed derailleur work with 11 speed?
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.
Can I use a 10-speed derailleur on a 7 speed cassette?
No, you cannot. A bike with a 7-speed cassette would also come with a 7-speed shifter and a chain that is compatible with 7-speed cassettes. This will make it impossible for a 10-speed derailleur to work on it. This is because a 7-speed shifter and a 10-speed derailleur have different pull ratios.
Does bike stem matter?
However, the stem has a significant effect on your bike’s geometry and, as a result, the handling and your ride position. There’s plenty to consider if changing or upgrading your stem, from its length and angle to the material a stem is made from and compatibility with your handlebar and steerer tube.
How do you change the stem on a mountain bike?
Quote from video: So the tools you need for this job are you only need one that's the best part you just need a multi-tool. From Maya stem I'm using a t25. You can need a four five or even a six millimeter.
Do I need a spacer above my stem?
When dealing with a carbon steerer tube, it is critical to have the steerer tube go all the way through the stem, in order to reduce stress on the end of the steerer tube. It is then necessary to have a spacer on top of the stem.
How tight should a MTB stem be?
A god rule of thumb is to tighten your headset cap bolt until it is causing some friction with steering and then back it off until it’s tight enough to keep the stack neatly in place. This is typically 1/8th to 1/4 of turn. Give your headset spacers a twist. You should not be able to move them much, if at all.
