- Trail Test. Swapped my MTB front rotor from 180 mm to 200 mm (back still 180 mm). Question: Does a bigger rotor on the front stop the bike better? Let's find out.
Want to watch me remove the old 180 mm and install the new 200 mm (including alignment and bedding)? Watch this video:

Get more stopping power with a bigger front rotor? What do you think?
Great clear video. Love the content. More please.
: )
Awesome trail!
Thanks! 👍
Just went from 180/180 to 200/200 on my Ripley and glad I did. So powerful ! Had to adjust my ready stance coming into tight corners to get my weight further back! I've found it to be a great upgrade and the increase in weight is negligible.
Totally agree. I am at 200/200 how too ... and would not go back. Rock on!
Hi, sorry, but in your video is small error. 203mm rotor gives 27% stopping power than 160mm. 180mm gives 13% better stopping power, than 160mm.
Equation:
Sh = ( ( D / 2 ) ^ 2 - ( ( D - 20 ) / 2 ) ^ 2 ) * 3.14 * 2
where D is diameter of rotor with 20mm braking area (width).
Thanks for clarification.
Glad to hear you liked this upgrade 👍 seams like a no-brainer really, very noticeable gains for not a lot of coins.
I'm in the process of upgrading 180/160 to 203/180 and looking forward to testing improved braking power😁
Hi, did you try already the 203/180 how’s it feels? I plan to change my rear to 180 but not sure
Think you'll enjoy it.
One way to find out. : )
Don't care about the functionality, I did it for the looks! lol
sweet shiny spinner
Nice bike 🚴 enjoy the video
: )
if you know the basic physical laws they teach in jr high school, of course. Also you need to know that a larger disk can hold more heat energy and has more surface area to be able to get rid of it.
I got to go back to JR High and take that class. It's been too long. Over 40 years. : )
Just a newbie in mtbiking. Given that he has 180 and 203...
How should should you modulate brakes in steep rocky corners and what rotor setup shoud you use?
A) 180F/203R - front modulation
B) 203F/180R - front modulation
C) 180F/203R - rear modulation
D) 203F/180R - rear modulation
Best to have LARGER rotor in FRONT. Front wheel is strongest stopper. However, you do NOT want to use all front brake in steeps and OTB (over the handlebars). Front wheel needs to roll through steep hits (and keep your weight back). For most brake scenarios, modulate (use) front and rear brake equally (same time).
The bigger ones should be better,but the disadvantage would be higher warp risk,what do you think,did they warp ? And thanks for the video
Thanks for warning. So far, zero warping. Just excellent stopping.
Did you have to get an adapter or do anything different to the bike to make the 200mm fit?
Yes. Needed new Rotor (200) and new Adaptor (40p). Also got new brake Pads (optional, but recommended). You can watch me do the entire process in this video:
th-cam.com/video/LQ2X54OUL8M/w-d-xo.html
It includes: installation, alignment, and bedding.
If SRAM, here is a helpful chart:

Good luck.
Did the lever feel any different after putting on the 200mm rotor? PS - your home trails look awesome!
David, thanks. Lucky to live here. Ride two blocks from house to trailhead. Good question. Lever did not feel different (amount of pull needed). Lever did move out slightly (due to new pads). Front brake slows down just a bit quicker now - noticeble, but not like double. Can really tell compared to old/smaller rotor in back. Like it. Probably change out the rear rotor too. Read that caliper change (2 to 4 piston) will add 10-15% more stopping power while rotor change 180 to 200 will add 30-40% more brake. Rotor swap is cheaper and easier.
i'm wondering how strong will be the braking power of an mtb if they turn the rim like a huge disc rotor and use a big caliper with the same brake pads like that of a typical disc brake caliper's pad hahaha I know its ridiculous but I'm just wondering what if hahaha Its like the typical rim brakes but of course those uses different brake pad made from rubber hahaha
Interesting thought. Weight might be issue.
I am 170 pounds, will installing a 203mm rotor in front destroy my fork? I mainly ride roads but with slightly steep downhills that span about 2-3 km.
No idea. Why damage your fork? What kind of fork? Check your fork manufactures website to confirm that you can switch disc sizes (and the range). You will also need the caliper distance adapter to switch between disc sizes. Finally, if back too, check bike frame manufacture website to confirm size disc you want to add. Good luck.
@@50mtb44 i only have a non-known hardtail bike from a sub-line of Trinx brand called Keysto. The model of the bike is Keysto Striker. It is a 27.5 er bike. The fork is just a basic fork included in it with a lock-out switch. 30mm stancheons with a IS disk brake mount. Currently, it has 160mm rotors on front and rear with a shimano mt200 hydraulic brakeset. I have upgraded most of the parts. Only the fork remains not upgraded. Will be going with Suntour Epixon i think.
What is the disadvantage and advantage the disc rotors
Advantages of disc brakes: more stopping power, less fade on big descent, safer. Disadvantage: maybe cost more that v-brakes.
Advantages of LARGER disc rotors: stronger stopping power felt quicker, grabs faster, better for heavier riders, less fade on long downhill, cools faster. Disadvantage: bigger rotor weighs more (40 grams each), might not fit your frame or fork, cost of adapter, harder to keep a larger disc straight (after hit on rock).
Do you know what difference a 180 has over a 160?
Nope. Bet you can find it on Google. That is what I searched for 180 to 200.
Anybody try 203/203?
Nope. Just 180 and 200.
@@50mtb44 I remember that rotor sizes are 140, 160, 180 and 203, seems no "200".
@@robin94539 depends on brand. Sram is 200. Shimano is 203.
Hey 50mtb - hope you're doing well. Just found this, dunno if you've seen it - th-cam.com/video/kykuJIoavnU/w-d-xo.html
Thanks.
