I’d like to thank Hambini for sorting the issues around the BB, all running perfect now.  Can I add that Cliff Pratt resolved everything to my satisfaction when Scott refused to accept responsibility

For as expensive as carbon frames have become, the bottom bracket should be inspected and the measurements written down on a certificate complete with matching serial numbers.

You treat these frames with real care.  It's heartening to watch a proper engineer at work.

I had a similar issue with a Scott Addict RC 2026 frame. One side of the bottom bracket shell was perfect (40.95), while the drive side was out-of-round (40.87–40.97). This caused noise while pedaling. I have to say, the shop reported the defect to Scott Italy, and they sent me an identical replacement frameset with a perfect bottom bracket shell...

1:45 besides the compliance Scott also offers a rear light to fit in there that is kinda neat

Coming from an engineering background and having repaired my bikes and friends BBS.
I have experienced this several times with bearings that were rough when fitted and lovely and smooth when removed. On each investigation, the frame was significantly under sized.
I actually believe it’s will occur more often, when you fit higher quality bearings with tighter internal tolerances.
It could be a lot of Bike shops may fitted cheaper, (they would never admit it) looser tolerance bearings and would on most occasions still allow the bearings to rotate freely when fitted.
My solution being a bit more basic, finding something under sized and with emery paper, a sharp knife, care and patience, like lapping valve seats, have removed the excess to achieve the appropriate sized and roundish ID. Then the NTN bearings that I normally use are super smooth when fitted.
So this can be achieved by a home mechanic, with a good quality vernier and patience🙂

Imagine creating a creaking noise like that on a new £5K frame in your own garage!! 😦😧!!

good thing he didn't try to visit the titanic on that thing

When hubby and I had a high end MTB shop in the late 1990s, we wouldn't touch a Scott with a ten foot pole. Seems that notion is still valid. Glad you could save the mess they made, interesting video.

7:52 man that cracking noise gave me PTSD

Hambini I found you again! Amazing 🙌🏼

Everything Propietary, Headset Area, Seatpost, Anything! I dont know Man...

That’s why I have a stethoscope as part of my bike repair kit. It’s great for checking wheel bearings and bottom brackets.

Great tech evaluation and QC of a frame that should be FLAWLESS at 5K!

At the end of the square taper, beginning of the Hollowtech, we would do a “cleaning pass” with a threading tool of every frame sold by the shop.. I’d say 1 in 10 frames needed it - and that was with steel and alloy.

This was pretty much SOP in the bike shops I knew, a good way to avoid worn out bearings and/or phantom clicking during the warranty period. Clients were more likely to splurge on a pair of Bora’s if the bike was perfect!

In 2026 you'd think that manufacturers would have these processes down to a fine art.

I love this channel because every time i watch it, i'm glad i only have a Ti frame with a threaded bb

Thank you for your videos Hambini. This is the reason I have not bought a new frame. You have saved me thousands of dollars! 🔥👏😊

Excellent! When the hole is too small we know who to call

I don't even ride a pushbike but I'm really enjoying this video.
