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.

What 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.
