- Опубліковано 20 лис 2021
- Whacky drivetrains have been making more appearances recently, but are they a fad? Has the technology pushed them to new levels? And are they here to stay? Doddy compares a gearbox bike with a traditional drivetrain system to see what all the fuss is about and how gearbox drivetrain tech might be here for the long run! - What are your thoughts on gearbox bikes?

Another advantage of having no cassette at the back is you can have the hub flanges wider apart and build a much stronger wheel for virtually the same weight.

Built my own custom titanium hardtail with a pinion gearbox and belt drive, and 3D printed an electronic shifter for it. It was weird getting back to a derailleur when I travelled to a local island without my bike, and the zero maintenance drivetrain has been magnificent - I’ve not washed my bike in over 1000km (whoops)
Doddy is a great host. The detailed explanation of the difference in feel of the bikes is exactly the kind of thing I want to hear if I’m deciding on a purchase.
Horses for courses. Nothing beats the feeling of a crisp and clean derailleur system. But I also have a gearbox hardtail, and the fact that it just always works is ideal. Especially when trying to fit your mountain biking in between work, kids and social activities. I hate it having to fix up my bike five minutes before I’m meeting my friends to go for a ride.
... and that is original Effigear box. They have now smaller and lighter version called Mimic.
Coming from the dirt shed and was looking forward to this. Doddy is the MVP
Once a name rider in the EWS takes on this tech it will take off. I believe it is the future for all the reasons you mentioned.
I love the aesthetic and clean lines of the gearbox rig alone. Let’s not forget Allan Millyard’s gearbox too, that’s a piece of work
The remarks about added friction should be relativized. A gearbox has more friction than a clean straight derailleur chain line. But as soon as your chain line is not straight or dirty, the difference gets a lot smaller.
I'm ready to accept anything to get rid of that cleaning fuzz!
Campagnolo: We made a 13 speed drivetrain. SRAM: Hold my beer. However, I stopped the video at the
Replace the chain drive with a belt drive and we would be getting even closer to zero maintenance.
I know that Doddy points out that it is not a comparison of bikes but the whole package makes a difference. It is a longer travel coil sprung bike with a more flexible steel rear triangle and it has a lot more sprung weight. All of these things contribute to more grip along with the unsprung weight. It would be interesting to do a comparison on the canyon where he switches between a heavy duty tire wheel and drivetrain combo, a lightweight tire wheel and drivetrain combo and perhaps even a lightweight combo without chain derailleur and cassette just for comparison of unsprung weight.
I think for UK riding in winter the gearbox is a no brainer, although, I do look after my bikes, particularly the transmission, so have very few problems with derailleurs. I can't understand why downhill bikes aren't already running gear boxes, they don't need loads of gears, additional friction is only a disadvantage when peddling a lot and it eliminates smashed rear derailleurs.
I've had a Zerode Taniwha with a 12 speed Pinion gearbox, and have had it from when they were first released a number of years ago. Some thoughts on the gearbox. I think there is more drag than a derailleur setup, particularly during break in, but you get use to it and largely isn't a factor. From my design experience I suspect the biggest contributor is the drag from all the seals, then from the fact that it is a constant mesh gearbox meaning all the gears are always spinning. When you are pedaling in a low gear, the other gears are turning relatively slowly so the drag isn't that much, but when you use the higher gears, the slow gears that aren't being used are spinning faster than the gears you are using. I believe due to this, the efficiency is pretty decent in the lower gears, but gets more noticeable in the higher gears. The gearbox should be reliable but mine had to go in for a repair when something in the shifting system failed. I understand that Pinion has upgraded this. It definitely adds weight to the bike, but it is low and central, which is where you want it. I also think the Taniwha is overbuilt so that adds a bit of weight. Shifting is something you get use to but there is definitely a learning curve so most experienced riders struggle with it when they first try it. It's something you need to commit to and it does come good. Once you are use to it, the advantages are that you can change gear super fast, you can change many gears as fast as single change, and you don't have to be pedaling to change gears. The down side is you can't shift to an easier gear without taking the load off for an instant, and though with a regular drivetrain you can mash a gear, it is not kind to the drivetrain, particularly the chain. Chains seem to last forever. I'm still on my original chain. For the bike, besides the advantages of taking the weight off the rear wheel, it also affords a lot of advantages for the bike as the suspension pivots can be placed to take best advantage of a single chain line and a fix cog sizes. So I like the system, but it is not the home run for everyone. If I was XC racing, I don't think this is a good option due to the weight and drag, but for gravity assisted riding, and general riding where the fun factor doesn't hinge on weight and efficiency, then I think it a good option.
Worth adding that gearbox back wheels don't need as much dishing, so they're stronger
I am so impressed with Doddy's clarity and his precision with word choice when describing and comparing the two bikes together.

I ride an R&M Delight Mountain e bike with Rollhof and belt drive after becoming fed up with cleaning mud and gunk from derailleurs and chains after almost every ride .
