Slacker BIKE With Slack-R Headset Angle Adapter - 9point8 - IS41, IS42, Specialized

[@andrewince8824]

I've never liked angled headset systems due to the fiddly installation. This looks like an exception. Seems very well thought out and well made.

[@kwennemar]

I've been kicking this idea around for a while and decided to order one for my 2017 Trek Stache this morning since you gave me a discount code. Your videos are really helpful and well thought out. Thank you for your work.

[@polishguywithhardtospellna8227]

Hey Ken, another viewer commented after you watched the video, that he run this part on his stache 2020 successfully for a year. Thought it might reassure you. Good luck

[@sixate]

I've been running this on my 2020 Trek Stache for over a year. Easy to install, great product, and it does make a difference in a good way. Highly recommend this product.

[@frustratedalien666]

Your videos are great for beginner bike tinkerers. My Trek Roscoe 7 has a decent 65 degrees head angle, so I don't really need the Slack-R, but it was fun to watch you walk through the whole thing. Cheers!

[@LoveMTB]

Glad to help and thanks for the nice words!🤘

[@jim6335]

I ran this on my 2018 Trek Fuel Ex. The results were pretty amazing. The stability was very noticeable. I did have a little trouble during the installation of the cups wanting to rotate as I tighten to spec even with carbon paste.

[@patrickgoogle4011]

Thank you for explaining this product, I’ve known about it for a while but never looked into it and now I’m interested. My 2015 Trek Remedy 9.8 is killer but it is pretty upright at 68 degrees so this may be a good choice. I do have 20mm of spacers too : )

[@d2cdl]

Great video, and well explained🤟I really like the fact that you get, what looks like, about 10mm extra stack height after fitting this. As a taller rider, I always find the front a little low for steep descending, so this kit kills two birds with one stone👊It's worth checking out the DMR Defy stem, as it has a really small stack height and might mean the difference between being able to use this kit or not🤩Cheers bud

[@GokkunGuru]

Very innovative product and a cheaper alternative than to buy a new slacker frame. Did you experience any creaking? It would be cool if it comes in different anodized colors for those who like matchy matchy.

[@marekzmazur2077]

I've been thinking about potential creaking with this Angleset. But when you think about the concept, it's the same principle as thread together PF bottom brackets. The conventional PF BBs just pressed in often creak. But the ones that thread together in the middle don't.

[@dcasandman]

I keep commenting today. I’ve watched this video before. I love my slacker headangle on my Tallboy. I’m really considering this for the light weight xc build chisel.

[@MTBfixHQ]

Personally if I wanted my bike to be slacker I think getting a longer fork is the best way to go. 1 degree slacker for every 20mm. Switch the 100mm fork for a 130mm fork and you will slack it out 1.5 degrees and if you don't like 130mm you could always add more air and it will be like a 100mm. The Slack-R is a great idea though I like 9point8, thanks for the detailed video as always

[@jaygames1598]

If you change fork travel, you often get the one positive with 2 negatives. You make the bb higher and the seat tube angle slacker. Most older bikes, that are good candidates for a slacker head angle, have a pretty slack seat tube to begin with. Things to consider.

[@MTBfixHQ]

​@@jaygames1598 This is true but those are only two negatives if you see it that way, I prefer a higher BB because so many roots in my area and just push the saddle more forward on rails to make up for the slacker seat tube. Also keep in mind this Slack-R isn't giving you 1.5 degrees of slackness purely from the offset angles of the bearings, you can see it will be adding 15-20mm of length to your axle to crown measurement which is what a longer fork does anyways.... so the Slack-R will also give you a higher BB and slacker seat tube lol

[@jaygames1598]

@@MTBfixHQ I have over-forked a 2006 giant reign which was so fun and a 2013 norco fluid which I put back after a week or so. I like a xc/short travel bike to climb as good as it descends. As for the bb, my 2020 gt sensor was a monster truck in high and there's definitely some positives with that.

[@jaygames1598]

@@LoveMTB Agreed. I've tried 20mm longer travel forks 3x and 2 were quickly put back to original travel. Looks like a great product.

[@allseasons765]

increasing fork travel will decrease climbing performance and fun. speaking from experience, I added just 10mm to my travel by changing the air spring, and I can really feel it on the steeper climbs. because of the steeper seat tube angle and completely extended fork, it is veeery hard to weigh the front end and the bike wants to wheelie all the time and I can't steer properly. Can't imagine what 20mm would do, probably much worse. Whereas just slackening head angle wouldn't have these effects

[@fmanuelsg]

Nice video! I have the same bike. I think that the headset it's the only out of date thing of the bike (angle and lockout). It would be very nice if you could measure the head angle once you have installed the kit as you do at the beginning of the video. Also it would very nice to check that the seat angle is not affected or at least measure how it is affected. The finally trick would be check if the slaker kit allows to install the across lock headset. Cheers!

[@garryhaines3066]

great video as always, i have installed a Works Components to slacken my head angle which is so much easier and the company was excellent in advising on what one to get.

I don't know how you tighten the assembly without the top cup turning! Holding both cups with all my might but even just a bit of torque makes the tol cup especially rotate...

[@LoveMTB]

You have to start the threads at the same time otherwise you run out of it too early. Assuming you got the right kit

[@LoveMTB]

Make sure that when you start the caps you thread the in about the same, as in couple of turns. It is possible that one of then cups runs out of thread before the other, and that's when they start turning.

[@Emolokz]

I feel like using a C-clamp would've helped you with holding the cups still while tightening.

[@ismaeltrindade8423]

I have a doubt: this solution is amazing for me to modify the frame geometry. But, what the limits? Can it modify the angle to damage the headset frame? For this modification, I think the frame will lost the guarantee. Anytime, I love this solution!!

[@Rhums]

I got one of this for one 2015 Epic FSR. Tight it properly has been a true pain. You make looks it far too easy. Both cups were turning as soon as I was applying some torque. Plus the more you tight it, the more the thread for the adapter is disappearing under the screw thread and it becomes very difficult to maintain the torque. But at the end, it works fine.

[@Rhums]

@@LoveMTB Once in place, it's glorious ! No regrets. It's a bit weird at the beginning when you're used to a pure Cross-country bike. I can't say i can feel degradation while climbing hills... but it's definitely better on tricky descent. My bike is aging but with the Slack-R, the geometry gets almost identical to the 2021 Epic... so for 120€, I got a 2021 Epic but with the FSR specs on it... All in all it's damn cheap and I can keep all the upgrades I made previously (actually everything except the frame :) ).

[@loxavilinares]

Hello, I want to change my bike angle fork but I'm a little lost. I have an Orbea Oiz M-10 2022 and the direction diameter is 1/8-1/2 integrated and 9,5cm long. As I see you know a lot about it, do you know if there exists any special kit for my bike? Thakns a lot!

[@Luckshot1761]

Nice Concept. Really like the idea in general. Removing Material from my frame in the headset area will never be an optiom for me though. And even if the diameter fits it does not mean it will fit your bike (e.g. cube bikes, as mentioned on their website). Also 30Nm seem to be quite a lot with such a small thread pitch. Should result in a pretty big preload. As it is right now this will void your warranty imo.
