All these time, I thought that crash recovery mode is some intelligent, software-based fail safe with a lil bit of black-magic on top of it by Shimano.. turns out, it's much more simpler than that.. I thought I'm a decent bike mechanic, used to work in LBS before.. turns out I'm a dummy as well.. thanks for the insight, learn everyday 😅👍

Dude! You are hilarious! It makes a change to hear diamond advice with a little mirth! Thank you, from France.

I find myself beeing in a conflict. Watching a new RoJ video, or watching the col de la croix ascend of the tour

Thank you!!! I'm not the only one who knew this. I think this is the first video on KZfaq describing how it works.

I’d *heard* of crash mode recovery, but had no idea how to do it, so I learned something today. You are a service to the community, my friend! :-D That ride footage… I hope that was a one-way road as it was so narrow! It’s odd watching you ride with the drop-off on your left side like that; seems so unnatural when I’m used to riding on the right side of the road, but I’m sure you’ve gotten used to it. Thanks for the video! This one goes in the Saved pile. ;-)

Thank you mate! Fixed my issue.

Outstanding! now I understand..... Last year on a multi day ride with friends I got stuck in the hardest gear after a refuelling stop. After much trying to get the crash mode reset to work, I rode to the nearest "Di2 Specialist" who were very kind, but unable to fix it. 6o bonus km later I caught up with the 'Team'; grabbed a 'support' car and drove a 200km round trip to home to collect my other n+1 steed. Got back around midnight just in time for last drinks. Back home after the Tour, I decided to remove the offending derailleur. When I bumped it it made a loud click and has worked flawlessly since! With the help of your profound technical knowledge, next time I'll just pack a hammer.😅

Just wanted to thank you very much for this vid! I was able to not only know what happened, but also fix my co-worker's Ultegra Di2 derailleur. He had hit a sizeable pothole and it threw it out of wack (surprisingly the two race crashes and getting hit by a car before that didn't throw it into crash mode).

I first came across your channel in 2018 while looking for information about installing Di2. More helpful than the Shimano instructions! Been coming back ever since for your quirky sense of humour, and your incredible video-making skills. Twice had to ride in crash-mode. Both times after stopping for a coffee at a friends house after a ride. No bumps or rough handling of the bike, just slipped into safe mode. Gremlins or fairies for sure. I knew about crash-mode but couldn’t remember how to disengage it. I guess I stumbled across it just by trying to shift through the gears.

Production Level✔ Entertainment ✔And Animations!

I am in the middle of installing my first di2 system on my bike. Thank you for getting me “up to speed”.

Every time I watch your descents I imagine an old Mazda rx7 and a Toyota Trueno 86 drifting through those tight roads.

I am one of those dummies 🤣 Didn't know crash mode existed because thank God I've never needed it. Funny I haven't heard of it anywhere else other than here...

yaaaay! Always appreciate a new vid!

Very happy Di2 12sp Dummy here, thank you!

Agreed, it is a great road. Thanks ROJ

Great advice happened to me a few years ago hitting a pothole the crash mould does activate even if you don't have an accident good idea by shimano just the first time it happens it make freak out a little bit... cheers 👍

Concerning the low camera angle: After *never* making that mistake myself countless times I learned that you can draw a line over the mount with some kind of touch-up pen when the camera has the correct angle. At least that does work for GoPro mounts. Keep up the great content! 🙂👍

Perfect timing for this dummy. Thanks!

Thanks so much I got problems , watching this video settle my problems thanks 🙏

Some top tips there! Cheers.👏👏

Excellent video. Interesting approach from shimano vs sram who demonstrate this with a hammer and hit their derailuer

Another excellent video, mate!

Good stuff, thank you!

Nice one 👍🏻🎉🔥

Great Content!

ayyy youve uploaded again

I had an interesting experience with crash mode: I was running ultegra rx with 1x chainring, and I put an XTR 11-40 cassette on it and backed out the limit screw. Works pretty well, until I put the clutch on one day, and the extra tension caused the derailleur to enter crash mode 😆 Turn off the clutch and it works fine again for thousands of km

Wow, these should be the standard instructions to get out of crash mode!!! Much easier to remember and implement on the bike 🚲. Thank you 🙏

My friend Ive been completely inspired and infatuated with the sound and feel of heading down hill. Your bonus clips literally bring me stoke I love riding up hill. Mainly to go down yes. But I’m absolutely fine with the suffer going up Yet, I’m to dang busy to train enough for weekend trips and I really wanna be doing 150-200km+ rides in and around all these Japanese roads To get to your level. Did you really only ride weekends? Like, your riding plenty weekday yea? You must be 😅 I’m having a hard time trying to find enough time to build up for them long hilly adventures here in JP. I’ve done 50Km 1200meters and 80km 800meters but dang do I wanna get to your level! Looks so fun Tips? Make a video !?!

and I have strange problem, rear derailleur won't shift into two largest cogs (no matter if I'm on large or small chainring). and when it go all the way down to smallest, it has two more shifts but motor click for few seconds and nothing happens. when I start back to bigger first two shifts move derailleur 1-2mm and third shift move chain to second cog and it goes above to ninth when it stops (there is enough room until the limit screw, just there are no more shifts).

So glad I watched this just two days before the British National Gravel champs as I hit a huge hole during the race and the rear mech stopped working in the 11t sprocket. However, it took me about 10mins to get it working again as pressing the shift button wasn’t doing anything that I could see. It came back but I was wondering if I was changing in the wrong direction? In my frustration I was probably trying to shift up the cassette (as I was stuck in the 11) when if I had actually tried to shift down multiple times it would have only taken a few seconds to start working again? Is there a direction you should be shifting to re engage the mech? I won the M50 race by persevering with the shifter after this video - so thanks!! 👏👏👏

Just found this channel. I don't even have DI2. So not sure why I watched this. Haha

Wow had no idea it was mechanical always thought it was the motor that did it

Do you have any specific comments about the direct mount on your emonda? Amazing channel

Hello I know this may not be the right place to ask but could you please make a video about how to buy a bike in japan ? How easy is it and are they cheaper than in us/europe ? Sorry I just discovered your channel and some videos are a bit difficult, an easy video for begginers looking to make a bycicle trip in japan would be really cool I think !

I have learnt alot from your builds have a bit of OCD and weight obsession. My favourite one is the xtr rotors I had 105 and upgraded to xtr after watching your content. The guy was surprised when I mentioned they were lighter than dura- ace. Is a reputable bike shop in Adelaide South Australia. Funny how the new group sets are using them. Is because of you that I got them.👍🙂

Man! I’ve had this happen twice now and had no idea what was happening. I ended up pushing the whole thing with my hand and it went back into place. I thought my derailer was broken. Mine won’t actually pop back in when I use the shifters so I’m not sure how you got it to work?

I prefer the Sram Axs crash mode…where the motor and the clutch desengage automatically and then adjust itself

Hey, my ultegra di2 went into dead mode after I slip the chain outwards. It’s not working at all. I tried everything

✌🏻 где такие кепки покупаете? 🤤

It is striking how many problems there are during the tour with the new Di2 ! Or is that just me?

3:42 Didn't know 12 speed di2 got rid of the junction box. Di2 is now another step closer to being as good as axs.

Do a video on the new Dura Ace RT-CL900 Rotors. I'm sure you are HOT on the trail for these??!! Shimano claims no more warping or ting, ting, ting :)

...since 2012?! ( did wire your crankset yourself?...

I watch racing and it seems occasionally that someone will have a problem with their drivetrain. I wonder if that is sometimes the problem. Maybe the derailleur gets hit in a tight peloton or something like what happened to you.

I switched over to SRAM eTap when it first came out, back in 2015 (I think) the same kit is still on the bike (frame has changed) and it's never missed a beat. I've been out on rides with my mates running di2 and so many times we've hit this issue, and everybody just looks at each other, fiddles about and then it all works again. Now I know why !!!

Have u seen @veloandres new enve disk, tubeless 896g wheelset?

I have that same frame. How light can you build the SLR up to? @Rides of Japan

I have a question, not really related, i you don't mind. Do you need to make any adjustment to the rear mech, if you interchange cassettes ratios? Thanks.

Where is the ride?

Something about these videos make them like ASMR. I could listen to you read the phone book with those dulcet tones and soft J's. (For people born before phone books, a phone book is a thing everyone used to get with all the phone numbers before we had flatscreen TVs) So, I am the dummy who still doesn't get crash recovery mode. Is it electronic? What is the benefit, you fresh and it doesn't keep shifting? I'm going to go look this up in a phone book. So the manual part is you move it with your hand to a better gear for getting home if the battery is dead? I still fear Di2 like it's Skynet, I guess.

I'm ready to upgrade my drivetrain. Not sure if I want to switch to electronic shifting. If I do switch to electronic, I may change side over to sram (force). Anybody know if I can run a 12 speed Ultegra cassette/chain with force etap axs derailleur?

Alert! Alert! Alert! A deep earthquake occurred under the Nankai Trough in Japan today. That is a very bad thing to see. I heard the Nankai Trough fault line is due to have a 9.3m earthquake in the near future years ago. Also, an earthquake swarm is occurring over 100 miles to the south southeast of Tokyo Japan. And people in southeast of Japan, get ready for a possible big 7.0m earthquake to happen there at any time now. According to dutchsince

Crash Course in Crash Mode

Just wondering, what out front mount are you using for your garmin, in the bonus clip...its just so sleek and sexy!

My di2 battery is draining even my bike is not in use i cant find the possible issue. Maybe you can shed some light. Many thanks. Im using the shimano dura ace 9070 the old system.

Why are the pulleys so quiet when he's riding at the video end? Di2 R8050 on many bikes are rampant with noise. Jealous why this guy has quiet clean drivetrain sound.

I'm now undummied

so it's like a mechanical fuse. I bet Japan has many insanely beautiful natural places. the women are nice, too.

You was right about the English, It's Eng-lish not Engle-lish. 🤣

The pro tour riders even getting stuck in crash mode ..what' a joke ..ride campy eps ..no issues

Brotha man, Imma gonna give you a thumbs down if you knock your english Guarantee its much better than my Dutch, polish, or what ever So cheers ✌🏻

Writing on cap is in poor taste to us old codgers. It comes across as thinly veiled variation of an offensively vulgar profanity. That is fine for your mates but detracts from your otherwise excellent video.
