Thanks for this! I've built a 1x9 system with a 500g 11-46 ali express cluster, a 200g XTR 9 speed mech and the little hanger spacer that came with the cluster. Controlled by a Deore shifter that way lying around. . Works really well. Cost me just under $100 USD and a bit of online hunting and learning. I've since scored a 300g XT 10 speed clutched mech for $50 USD and will get an ali express 360g 11-50 10speed cluster for about $90 USD. Got a Deore 10 speed shifter for $30 USD. Its fun scoping cheap stuff online ... people are basically giving away great gear that is considered too old. Never owned any XTR gear before. I'm a nerd who is enjoying learning this stuff. For anyone else, that box-type deal gets the same result with new, heavier parts. Nice.

Upgraded my Rock Hopper Expert RD to a GX over the weekend. Shifts much cleaner then the SX 👍

Thanks very much for this objective review! Box Components may not have achieved Nervana, but they have produced functional options for the common man. I believe refinements will come, and I support them all the way.

I rode my gravel bike for the first time on that trail today! Can't wait for more gravel content. Good informative channel👍

9 speed concept is really great to be honest. During trail rides i usually do multi shifts with my 12spd, but i guess this 9 spd is enough to have easier shift

Nice and concise.

Awesome! I have a 1x12 deore and getting the shifting indexed perfectly is a challenge. If I fall and the derailleur gets hit even slightly the shifting goes all out of whack and needs to be adjusted. Feels like more gears is not always better especially on a MTB you intend to throw around. 12 speeds is really nice when it works though

Great series of videos and thank you for you insight. I have one question about the compatibility of the Box Components cassette.

As a 1x11 speed flat bar gravel rider I have to say that I'd rather have chosen 9 speed for the single reason that there's less shifting required for rapid gradient changes. Especially important as you can't just drop to the small chainring. In fact, I'd say the super cheap Box 4 8 speed setup would be a real contender for me too....

Question. I have a 2021 rockhopper comp that was already 1X. I wanted the 11x50 so I thought I’d go for the box 2. I didn’t realize that I had a direct mount derailleur hanger. So now I have a derailleur that doesn’t align. The box site says it not compatible and I didn’t catch that. Did your rockhopper have the correct b-link derailleur or did you have to find one?

I am thinking if upgrading the BB to a hollow tech will be useful. I’ve already got to upgrade the worn hubs

Just upgraded my girlfriend’s Rockhopper Sport with a Box Two drivetrain with a 52mm chainline crankset and the 52mm chainline seems to be a tad too wide. How is this bike doing with the 56.5mm chainline on the Deore crankset? Do you notice any expedited chain or cassette wear so far?

I'm thinking of turning my old Fuji fitness bike into something a bit more gravel friendly. It currently has a 2X Shimano Sora drivetrain. I want to go with Box Prime 2. But what of the crankset? The Fuji currently has the stock Shimano Sora, 50/34T. Any recommendations on what to switch to that will work nicely with the Box 2 Prime 9? Thanks!

Hello new here, what 1x size crank sproket your using 32t or 34t... and why?

I have an old specialized tricross and the cables exit the downtube the same way. So easy

how does 1x11 compare to a 3x8 for steep hill climbs and top speed? does the 3x8 win both? im looking to change my 3x8 to 1x11 or 2x11

Looking for some advice, I'm looking go upgrade to a 1x drivetrain on my rockhopper sport. Will any groupset fit or do I need to look for a specific spec? I don't know much about bike parts 😅

@TheBikeSauce

Hey Ben. This is a really loaded question, but for your bike, you’d want a cassette that will fit a shimano HG free hub (anything 8-11sp shimano cassette will work). You need a derailleur to satisfy both the max cog size as well as the overall drivetrain capacity. You will also need a new crankset with a single narrow-wide chainring (I believe the stock 2x cranks have riveted chainrings). It’s also a good idea to get a chain spec’d for the number of cogs on your cassette

9 is 🎉

Awesome upgrades. I have a 2019 Specialized Rockhopper 9 Speed. I'm going to replace the entire drivetrain with Shimano M7100 SLX 1 X 12 Speed group set I'm have a question. Since the rear hub is a 9 Speed. The Shimano SLX is Micro Spline Freehub. How can I convert the 9 Speed to Micro Spline Freehub body to fit the new 10 x 51 cassette? I hope you can be of assistance. Thanks you in advance.

@TheBikeSauce

2 жыл бұрын

That’s a bit tough. you’ll need a new hub, and unless the rim is really high end, it’ll probably be cheaper to buy a new wheelset. I’d go with a solid 11 speed system that you can mount on your existing freehub body. You’ll still get massive range and for mtb you’ll probably not notice the lack of smaller increments between gears

@TheBikeSauce

If your plan is to just swap cranks from a 3 ring setup to a 1 ring setup, you may not be happy since you'll lose substantial gear range, as the stock cassette isn't as wide ranging as a 1x setup (since it can rely on the front chainrings for range). You can do it however, and you don't even need new cranks most likely. Just look into a 'narrow-wide' chainring with the proper mounting and, if your current cranks allow, remove the 3 rings, and replace with the single narrow-wide ring.

Why does shimano even mention this compatibility on their websites, couldn't find an answer anywhere. Thanks again for the time

Yea it’s confusing for sure. It has to do with the outer dimension of the chain. Inner dimension is pretty standard, so the chainring itself doesn’t need to be specific to a gear number (8,9,10,11) speed. I do believe some 12 speed chains may use a different inner diameter however
