The front derailleur is one of the most important moving cycling components on the bike.
The derailleur at the front attached to the frame and moves the chain between the chainrings on the cranks. Is needs to be kept clean to keep shifting smooth, a rusty or grimey derailleur can often be the cause of the chain jumping or dropping whilst shifting.
Easily adjustable to allow you to make changes to the indexing of the gears, we have products from a range of manufacturers including Shimano and SRAM. The front derailleurs we have are made to go with their recommended groupsets.
