| Component Notes |
Shimano’s E-type front derailleur traditionally included a backplate that was held behind a threaded bottom bracket. This pre-dates current direct-mount designs and was filler for when brands started to move away from traditional band clamp derailleurs.Nowadays, ‘E-type’ is more commonly sold without this backing plate and is sometimes referred to as a ‘low direct mount’ or ‘E2-type’ front derailleur.Following the direct mount above, this is the next most common form of direct-mount derailleur and features two bolts 22.1mm apart, with right-side hole of the derailleur 5mm forward offset to the left one.SRAM also offers compatible derailleurs with this mount type – they’re called ‘S3’ or ‘Spec 3’.This mount style is becoming increasingly popular, because it's near-hidden if you decide to exchange front shifting for a simpler 1x setup.Tire Size - The Chameleon will accommodate up to 29x2.5 or 27.5x3.0. If you adjust the dropouts back a bit (lengthen chainstays) you can fit some 29x2.6 tires as well |
