Similarly one may ask, what is a top pull front derailleur?
Some front derailleurs are designed to work with cables which pull upwards from above the derailleur, and some work with cables which pull downwards from below. They are called “top-pull” and “bottom-pull” respectively. Locate the cable stop or routing on your bike frame through which the derailleur cable will run.
One may also ask, what is band on front derailleur? There are two types of road front mech mounting: band or braze on. Band: this as the name implies is a band which clamps around the seat tube of the frame. There are two band sizes 31.8mm or 34.9mm so check current model or frame manufacturer's recommendations.
Similarly, you may ask, what is the difference between top pull and bottom pull derailleur?
Traditional front derailers are "bottom-pull", operated by a cable running up from the bottom bracket area to the derailer. "Top-pull" derailers are operated by a cable running down from above. Run the bare cable under the bottom bracket and up to the derailer's anchor bolt.
What is down swing derailleur?
"Swing" refers to the location of the pivot on the derailleur and is totally independent of the pull. IIRC Top Swing refers to a Low Clamp design (Only Shimano does this) and Down Swing refers to your typical high-clamp design.
Related Question AnswersWhat does the front derailleur do?
The front derailleur moves the chain between the three front sprockets. Unlike the rear derailleur, the front derailleur moves the top part of the chain, which is under tension when you are pedaling. This means that in order to switch sprockets on the front, you have to ease off on the pedals.What does braze on mean derailleur?
Braze on mounts are commonly riveted or bolted to road frames. This is the more common form of road front derailleur mounting and can be made compatible with frames needing a band clamp too. Braze-on derailleurs just feature a small nub with an internal thread to accept a mounting bolt.Are SRAM and Shimano front derailleurs compatible?
yes, it'll work. caveat: depending on how much smaller your middle ring is, you may have problems shifting up/down. too large a tooth difference can sometimes cause issues here. but the basic question of sram shifter pulling cable for a shimano front mechis easy; it'll work fine.Does SRAM front derailleur work Shimano?
Yes, you can mix Shimano and SRAM front derailleurs and shifters. It's the rear derailleur that is not cross compatible, with the exception that SRAM has made 'Attack' shifters that will work with the Shimano rear derailleurs.Will a triple front derailleur work with a double crankset?
Triple FD will work on a double chainring if the difference in teeth number between the chainrings isn't bigger than 12. Compact cranksets, with two chainrings that vastly differ in size (usually 34-50 combination) will work well only with double FDs with the curve appropriate for the big ring size (50 to 52).Can I use any derailleur for my bike?
A derailleur for your mountain bike should match the specifications on the original derailleur. That is, while it doesn't need to be the same model of derailleur, it does need to be the same brand, in almost every case. Meaning a 7 speed will fit for 5 and 6 speed bikes. An 8 speed will work for 7 and 8 speed.Can you use a triple shifter for double?
Can I adjust a Shimano mountain bike front triple-trigger shifter and front derailleur to work on a double crank? Yes you can, as long as you use a mountain front derailleur. In other words, shorten the cable so the derailleur moves immediately from the smaller chainring when you push the lever.Are derailleurs interchangeable?
The important thing is that the different ratios means that rear mechs and shifters are not interchangeable between manufacturers – Shimano rear mechs must be matched with Shimano shifters, and SRAM with SRAM (however Shimano front mechs can be used with SRAM shifters).What is the difference between braze on and clamp on derailleur?
Clamp-on have a metal clamp that wraps around the tube of a frame that doesn't have a built-in mounting tab for the front derailleur. Braze-on derailleurs can be mounted to frames that don't have a mounting tab, using an adapter.How do I know my bike chain size?
L = 2 (C) + (F/4 + R/4 + 1)- L = Length – your chain length in inches (rounded to the nearest inch).
- C = Chain stay – the distance between the middle of the crank to the rear axle.
- F = Front chainring – The number of teeth on the largest (front) chainring.
- R = Rear cog – The number of teeth on largest rear cog.
