I bought Trek Fuel Ex with Alu frame at 2020. It has press-fit bb. Since day one I had zero issues with bb, still on original bb, which is Shimano deore. BTW that bike experienced everything, jumps, lots of pedaling, dust, mud, rain... Honestly I would like to have threaded bb, but it is not end of the world if you have press-fit which is made good.

Yup! As I mentioned in the video, when press fit is done right, it will work great without issues. In my personal experience with Trek, Me and 4 other friends have Farley's, which we all bought new. Three of us had our frames warrantied, with one of the guys having it warrantied twice, all due to the bottom bracket. Trek was absolutely AMAZING at handling it. HUGE props to them. But still, out of 5 people, it cost them 4 extra frames. Trek and specialized are the dominant players in my area. I've worked on, or known, MANY people with pressfit BB issues with these two brands, which is to be expected considering how dominant they are around here. Scale is the issue. These two companies probably produce a few million bikes (of all types) a year globally. The cost savings moving from threaded to pressfit at this scale are huge. But manufacturing consistency for press fit as this scale is much harder to maintain than threaded. And as I mentioned in the video, anyone can fix a threaded BB if something is wrong. Pressfit needs more experience to do so.

Simply awesome! I was sitting front row as you preached your rant and couldn't agree more. BSA/T47 BB and non headset cable routing are my 2 non negotiables and will never own a frame without either. That Maxhit BB looks interesting, but I've had such good luck with good ol' DUB BSA BBs that I haven't even thought about straying.

AMEN Brother! I'm TOTALLY with you on this. I honestly wish people would not purchase bikes with headset cable routing so it can die off. The maxhit is a first for me. Had my reservation considering the price, but got it for 20% off so I figured why not try something new and different. If it wasn't for the discount I would have been like you and stuck with something that I know works without issues 👍

Totally with you on this myman.👍 I know there are some die hard press fit people out there, but in my experience, I've seen WAAAY more issues with press fit then threaded, percentage wise, over the years. And its not like I'm some kind of bike shop that deals with thousands of bikes a year.

Great stuff - I'm watching this whole series as I do want to build up a bike some day. Thanks! Got a good rule of thumb for when to use grease vs anti-seize?

@zoubtube 3 ай бұрын

I'm glad to hear the videos are helpful for you, and thank you for taking your time to watch them. A good rule of thumb is, in a high-pressure/high torque static application, especially with non-matching metals, you want to use anti-seize. In a low-contact/pressure moving parts application, grease is best. Hope this helps and let me know if there are any other questions

Totally agree. No way im buying any bikes without threaded bb. Stay away from press fit frames.

Mine is absolutely fine. Carbon frame (Scott Spark) PF 92 Shimano XTR BB and Crank set (24mm is standard Shimano). Easy to fit and no creaks.

@@johnlesoudeur3653 I totally get it, and I know people with pressfit that don't have issues. But as I tried to explain in the video, the issue is scale. The chances of manufacturing a pressfit solution at scale without defects are lower than threaded. And more importantly, imo, if there is a defect, it can be much harder to solve with a pressfit BB as it can require significant experience to fix, whereas anyone can solve threaded issues, barring it's not something major like a cracked BB shell. I'm more than confident that yours will work just fine for years to come. 👍

Wow, this BB is impressively good. I worked in a shop as a summer job and got a chance to tap the BSA BB on my Orbea Laufey alu frame. It was so badly ovalized that the tap was indexed at 12 and 3 o’clock. I ran the tap twice, but it was still pretty bad and I just ended up installing the new bottom bracket in the wonky shell. In this case, do you think it still could be fixed with a sharp tool, lots of cuting fluid and patience, or should I just try to warranty the frame which is 5 yo with pretty beaten up paint job ?

@zoubtube Күн бұрын

If you attempted both facing and taping and still it was offset, I would send it back under warranty if It's still covered. They should replace it or, at a minimum, fix it, no matter how beaten up the frame is. Bad BB alignment is a manufacturing issue, if they fight you I would fight back and hard. Thanks for the comment

I did not want pressfit, but as I bought a bike right after Covid I did not have a choice. Either pressfit bottom bracket or lots of other things I'd had to spend time and money to swop out. The higher end brands tend to opt for pressfit unfortunately.

@MatTancock 3 ай бұрын

Not anymore though thank god, brands started to move back to threaded during covid. Even specialized did it.

As I mentioned in the video, when press fit is done right, it will work just fine. It's when there is a manufacturing issue that it can require some significant experience to solve with pressfit, whereas with threaded, anyone can solve it. There are HUGE manufacturing cost savings for frame makers to move from threaded to press fit. Specialized and trek alone probably make a few million bikes a year globally. Even if it's a dollar savings per bike, it's big money at scale. So I get the move. BUT, many in the industry are now moving back to threaded for mountain bikes. And I wouldn't be surprised if it continued. As always, time will tell. Ultimately, if you have a press fit, and it works without issues, then I wouldn't worry about it. Chances are high that it will keep working without issues. Just make sure to go out there and enjoy it! 👍
