Bottecchia 8avio Revolution 105 Disc: Reading the Listed Gearing
Bottecchia 8avio Revolution 105 disc buyers should read beyond the groupset heading. The manufacturer lists a 57DM complete build with Shimano 105, a compact double chainset and a twelve-sprocket cassette. Yet one control entry disagrees with the headline. A useful purchase enquiry preserves that disagreement instead of silently choosing the most convenient specification.
Read the Bottecchia 8avio Revolution 105 disc gearing
The 57DM heading and group entry say Shimano 105 24s DISK. The chainset is listed as 50/34, and the cassette as Shimano 105 11/36 12s. Those are separate pieces of information: two chainrings at the front and a cassette entry explicitly marked twelve-speed at the rear.
Keep the tooth counts when comparing another bicycle. “105” alone would hide whether its chainset and cassette have the same listed arrangement. These numbers describe the published build; they do not predict your climbing speed, preferred cadence or how a particular hill will feel.
The controls line needs an answer
The same page calls the controls “Shimano 105 22s DISK”. That contradicts the 24s heading and twelve-speed cassette record. No corrected manufacturer notice is established here. Ask the seller to identify the actual controls, rear derailleur and cassette together, preferably with readable part markings and a written build confirmation.
Distinguish a component list from a photograph
The blue historical Bottecchia visibly has down-tube shift levers. It is a useful reminder that a brand name can span very different control arrangements. It is not an 8avio Revolution photograph, and counting its visible levers cannot authenticate the transmission fitted to a present 57DM offer.
The 8avio Revolution product record anchors the local model being discussed. The 8avio Revolution listing identifies the colour as B2 Grigio Verde Opaco. Treat that identity statement separately from the manufacturer's unresolved control description and from the older blue bicycle.
Confirm the entire offered configuration
The table also names Shimano 7070 disc brakes, 140/160 rotor figures and GPM wheels described with axle12. Obtain confirmation of the complete supplied arrangement before ordering replacement transmission parts. A matching brand or speed word is only part of a component identification, and this page does not approve a conversion.
Use the Bottecchia background guide for the broader range, then return to the topic index for separate frame and brake questions.
