Entry Level Mountain Bike Upgrades - Box Four 8s Drive Train Upgrade! - Bike Repair

Tired of your multi ring drive trail? So get rid of it!
Check out the Box Four 8s Drive train and some killer components!
In this episode of the Entry Level Mountain Bike Upgrade Series I'll be replacing the entire drive train on the DiamondBack Over Drive. I'll be installing a solid Wolf Tooth Drop-Stop chain ring to replace those 2 rings up front on a RaceFace Affects crank. Those cranks are connected to the bike with a beautiful red bottom bracket provided by Wheels Manufacturing. As for the rest of the drive train, that's all from Box Components are look SICK! In our next video we install a PNW Dropper seat post so stay tuned! Let's jump into some mountain bike upgrades, learn about bike repair and do some well deserved mountain bike maintenance.
-- IF YOU LIKE THE BOX 1X DRIVETRAIN --
--YOU MIGHT BE INTERESTED IN THESE FACTS --
This 1x system has a great gearing range. The 42t low gear will offer you some killer climbing gears.
Because of this great gear range you can finally toss that front derailleur system. Now extra shifter on your bars and one simple clean ring on the cranks. Love it!
The included derailleur includes a clutch to keep constant tension on the chain eliminating chain slap and dropped chains. This clutch can help eliminate a chain guide.
Prime9 Technology is a counter-intuitive philosophy based on the “less is more” theory. It embraces tange without adding complexity. The outcome is fewer parts, reduced weight, and increased durability!

inguardabile.

[@WOLFTICKVIDEOS]

We still have not tried out the Box groupset, curious about how it performs. Is that dropper post 27.2mm? Good series man. Thanks for the video.

[@rgmtb]

I'm quite happy with the system so far. No, this is not a 27.2 dropper but PNW does make one! kzbin.info/www/bejne/f5LUepWvadmbf7M

[@DorkyThorpy]

For anyone (like me) who thought of mixing box derailleur with shimano shifters, apparently you can't. Cable pull is different.

[@rgmtb]

I've never tried that but could see how it would be a bad combo.

[@theking_023]

What is the teeth of your cassette? Thank you!

[@ianrice1778]

I have a 2022 Trek marlin 5 n I installed a budget 1x buy just putting on new crank arms n a single chahinring. Now I want to order the box 8 speed that got just installed. I not a pro bike machanic but I know some stuff n your videos help big time. N I had the same diamondback as you 👍

[@taylorshiver3284]

Can't wait to see the rest! Do you still plan on showing how to change that stock crank to a 1X like said earlier? I think that is what I am going to try and do.

[@rgmtb]

Here ya go, check out these two videos. I wanted to do more with this series but it's already taking so long that I need to wrap things up. If you have any questions just let me know. I really happy to help :-) kzbin.info/www/bejne/rpWbg3l5pb12aJY kzbin.info/www/bejne/f4LYgZJ7ipx1nKc

[@andrew.cho_]

This has showed me so much, thanks soo much

[@kieranharvey348]

Thanks for the video. Did you not need a b-link to attach to the deraillieur hanger? Their own instructions imply its needed but you seem to run it just fine without

[@rgmtb]

No I did not. Normally a b-link is only needed if you are running a rear mech that does not have a cage long enough for the big gear on the cassette. I'm running the complete kit so everything works fine 👍

[@DorkyThorpy]

@@rgmtb I'm not sure it to do with the length of the cage. Although I did try a short cage with a 11 - 42 cassette and a link, but not enough "chain capacity".

[@Loftrocket]

Mechanical brakes!? Omg!!!

[@rgmtb]

Yeah, I'm not really in love with this style of brake. Well, I haven't tried a set that I've been impressed with yet.

[@B1KER]

Stopped by to see what you've been up to. Good stuff Gene!

[@rgmtb]

Thanks man! I've been watching your weight loss videos. You are very motivating buddy and a tip of the hat goes out to you.

[@B1KER]

Regular Guy Mountain Biking Thanks man. I climbed that trail we descended together last weekend. Was way better going down. 😂 Made me think of ya. Was wondering whatcha been up to. Looks like you’re keeping busy. 👍

[@lachlanmartin4046]

Hi

[@stevebennett3587]

Great video👌but i couldn't set up the box four derailleur as well as a shimano set up, not quite as smooth.

[@seanbickford2842]

I've got the Box 4 groupset on my Kona Blast and it rocks . Love it.

[@ianrice1778]

I have a 1x square tappered bottom bracket so do I need to have a hollow tech BB to use the box 4?

[@rgmtb]

No you do not. Sorry for the late reply. The staff at Box are super helpful so you might want to ping them if you're concerned

[@charliemtbaustralia5308]

Awesome, always teach me some things

[@rgmtb]

Glad to hear it!

[@soloride7474]

Sir wala bang cross chain amg 1x8 ?

[@edotalmor9208]

Good video. Even the colors came out nice with the red and black touches. For sure the replacement of the BB and cranks is a big upgrade compared to what came stock on the bike.

[@rgmtb]

Thanks man! The bike looks mint and I can't wait to get it done!

[@fernandomaldonado3877]

Is that chainring 104 bcd?

[@mtbboy1993]

5:26 why did you use a mallet? was it really necessary?, with the 30mm cranks I don't have to use a mallet, I jut have to hold it and screw in the bolt.

[@rgmtb]

Just following the instructions. I didn't see much value in the mallet either but the instructions showed it. It really didn't do anything.

[@mtbboy1993]

@@rgmtb oh only situation I use a mallet on a crank is when it it's bit resistant to get out of the bottom bracket.

[@matt-g-recovers]

Don't need 12 speeds, want lightest. Are there still lightweight 8 speed setups? Love the series.

[@rgmtb]

That I'm not sure about but I'm love'n the Box options. #9isfine with me :-) HAHA

[@marvsvins2588]

If I buy a rd and shifter only how much that? Pleaseee reply meee idol

[@rgmtb]

I'm not sure. I don't sell these, just use them. I know you can buy just separate parts so you'll need to check there site. I've got a link in the description to help.

[@lachlanmartin4046]

Keep up the great work also first

[@KelvinChanMcSquared]

What are the tooth count of the chainring and the 8 speed please, love this build

[@phatlakien9735]

the cassette is 11-42, but the chainring tooth count is 36, I guess?

[@matiparada682]

is the clutch stiff? greetings from Chile

[@triangle8194]

Yes

[@mikieson]

gonna look great Gene!!

[@thegamingkid783]

Do I NEED to change out the bottom bracket to put a box 4 on my bike?

[@rgmtb]

No not at all. I needed to because I wanted to change out the stock cranks 👍

[@thegamingkid783]

@@rgmtb ok then with that being said my bike has a 1 by in the front so i wouldnt need to change anything out crank related then?

[@rgmtb]

That is correct but I would reach out to Box and tell them what front ring your using to make sure it will work with their system. I wouldn't know that information.

[@thegamingkid783]

@@rgmtb Ok thank you my fine sir.

[@pollo369123]

Is it necessary to replace the bottom bracket?

[@rgmtb]

Nope 👍

[@pollo369123]

@@rgmtb Thank you! Another question, I have this exact bicycle, what is the model Park Tool did you use to pull the cranks off?

[@rgmtb]

@@pollo369123 So I have the Parktool CCP-2 but that is now discontinued. The new tool is the CCP-22 and I have that now listed on my Kit for this bike build ;-) kit.co/rgmtb/mountain-bike-upgrade-parts

[@alexjohnson668]

My rear chainring starting starting to hesitate in shifting what’s could be going on. What do I need to do fix it.

[@mtbboy1993]

hesitate?, might be that it's worn, chain might be worn, chaining might be worn, or front derailleur needs to be adjusted, the chainring might be bent, if you struggle with cassette too, the cogs might be bent, and teeth might be twisted or bent, but if it's not too crazy you can fix that with a flat head screwdriver. if chainring is bent you might be able to bend it back using adjustable pliers. but really I recommend to use single chaining setup, direct mount like Gene used here, no spider to bend.

[@alexjohnson668]

Johannes Nilsen I don’t use a derailleur on the front with my 1x. like it tries to shift then it goes back to the next gear.

[@mtbboy1993]

@@alexjohnson668 do you mean it jumps between several gears, instead of shifting to one gear? if so do you mean the chain ring on the front or cassette? if it's chainring, then that's probably wire tention or limit screws need to be adjusted. also if you changed cranks with chain rings you miht need to readjust it cus the offset can be different.

[@alexjohnson668]

It’s my rear cassette that giving me issues. I rode last night it seemed to do better.

[@mtbboy1993]

@@alexjohnson668 it might be your hanger is bent and the frame is so flexible you are bending the hanger, so if hanger gets bent again it might have been bent for the better this time, or it can be the wire that shrunk slightly due to temperature change, this is common you might need to adjust it in the evening, cus it gets colder then it shrinks, and in the middle of the day it gets warmer so it expands, so you need too loosen it, but of course that's with big temp change. it might be the rear derailleur that has play, so if it is paly, you might shake the bike so much that it moves into a better position and then it shakes some more and it worse again, if there is a lot of play in the parerlogram, and this happens that's an symptom that means you need a new rear derailleur, unless it's one with bushings you can replace like on BOX One & Two for example.

[@ElderlyAnteater]

how does the shifting feel - are the jumps between gears too large?

[@triangle8194]

Shifts by is very tight. To compare I had a eagle box and it felt cheap compared to this thing.

[@triangle8194]

Shifting* not shift by

[@TheRealPervySage]

Is that a 32 or 34 tooth crank?

[@rgmtb]

Almost positive it was a 32.
