Everyone seems to have a problem with front derailleurs – SRAM swore to kill them with limited success. Now, Classified, a Belgian company tries something that is actually tried before. I’ve never seen any product they made before, and I highly doubt it’ s a bike component company. Rather, they seem like many companies come up with a good product and attract some funding. It’ s also a small company that looks to be growing. Frankly, I’m not interested in company stories, as they’ re stories after all, and I’ ve never been a fanboy of any company or any product. Basically, Classified Powershift is a wireless -Bluetooth- operated, 2 speed gearhub without a freehub, instead, a proprietary cassette. Dubbed as “revolutionary” by bike media, it’s nowhere nearrevolutionary, as this was tried before, by a bigger and older company… Continue Reading Classified Powershift, front derailleur killer ?Continue reading

What is Shimano’s Di2 in detail, first successful electronic shifting system
Electronic shifting is not a Shimano invention, but it’s Shimano who did it commercially viable. It all started with Shimano Dura Ace 7970 Di2 in 2009, for road bikes, then came the XTR version for MTB, GRX for gravel bikes, and Alfine Di2 for gear hubs. First Di2, Dura Ace 7970 Di2 and newer Di2 versions are totally incompatible: the 5 plug version is very simplistic: it’s just wires connected to switches and derailleurs across junction boxes. Newer Di2 versions though, use CAN bus for communication between components. CAN bus is known for its extensive use in all modern cars, and became the norm for even the cheapest ones in late 2000’s. But CAN bus, being a data communication protocol, can be used in anything, and it is, including machinery. Unlike Sram’s eTap, which is designed to be wireless… Continue Reading What is Shimano’s Di2 in detail, first successful electronic shifting systemContinue reading
Mysterious disappearance of Chinese electronic rear derailleur, WheelTop EDS OX
I’m annoyed by electronic drivetrains, because of their vendor lock nature: you cannot use shifters from any other manufacturer, though it is perfectly OK to implement. But the most annoying part is, they are designed to make you spend more. There is no reason for an 11s electronic rear derailleur to mismatch with a 10s cassette. Anyone who knows a few about electronics already knows it’s very easy to make it work with ANY cassette. Jockey cogs will need replacement, but that’s a very easy obstacle to handle properly. WheelTop is the first manufacturer that came out with a decent design, that is advertised to work with 7 to 12-speed cassettes. Now, the product disappeared, even from the company website. I won’t be surprised to know they had troubles with Sram, maybe Shimano. Thing is, I’m sick of patent trolling.… Continue Reading Mysterious disappearance of Chinese electronic rear derailleur, WheelTop EDS OXContinue reading
Why electronic groupsets like Shimano Di2 are the future?
For years, many photographers insisted on DSLRs and ignored mirrorless cameras. Then, something very silly happened: camera makers started making mirrorless cameras with a DSLR “hunch”. Now, everybody is flocking to mirrorless cameras, selling their perfectly fine DSLRs for pocket money and grabbing mirrorless cameras at highly inflated prices. Why? People doesn’t like change. But when it’s unavoidable, or that change provides real opportunities, they follow the crowd. Electronic groupsets is good for ordinary people like you and me. The reason is not the groupset itself: they’re heavier and more expensive. Thing is, in Shimano-speak, they are capable of “syncro-shifting”. For those who don’t know what it is, it automatically adjusts gears so that each consecutive gear combination that is selected is the perfect combination. Let’s say you have hypothetical 3s chainrings, namely A,B,C; A being the biggest chainring. Then… Continue Reading Why electronic groupsets like Shimano Di2 are the future?Continue reading
