@MRGRUMPY53 Given that the amount of extra friction and power loss from that abysmally designed GXP will probably make the power meter pointless. And given that the axle will wear out pretty quickly due to under-rotation of the bearings because GXP is garbage. Yes, bin it and get a Shimano crankset with a new power meter.

@MRGRUMPY53 For the normal non pro rider, the power loss will be hardly noticeable. Pro riders won't have GXP in their bikes anyway even if they're sponsored by SRAM, they'll have custom built BB usually based on 386 Evo or similar 30mm. The issue for normal people comes from needing new bearings more often to the point where it becomes a pain. Then ruining the spindle because of the bad design putting all the load on one side causing under-rotation and galling on the other. If you have time and money then it makes no difference what you use but if you think £3,000 on a bike is a lot and want it to last a few years or don't want to be replacing bearings every few months to avoid creaking and loose cranks then GXP should be avoided.

I love those bottom brackets. Have them on all three of my bikes.

Good luck fitting that to an orbea bike. Oval holes for bearings

So I count myself as a Hambini fan, but many comments under this video are super unfair. Seems like some of you will be happy only when aerospace-engineers start to make simple bike-maintenance videos. I wanna react to some of the comments trolling some of the steps. Someone wrote GXP is crap according to Hambini. Might be, but Oli is not encouraging here ppl to switch to GXP. He is using it as example of BB change, because he happens to need it on his own personal bike, where he decided to use it. .........about anti-seize. Oli said, to check with manufacturer what to use as it varies from model. .........someone complained about hammer use on carbon. Well, hammer was not used on carbon, but on tool that was in contact w/ old bearing. Every bearing extractor requires use of hammer. Also Oli used it safely. And also I´ve seen Hambini to use hammer in many videos working on carbon frame. Not directly hitting carbon - obviously. I think Oli did good job and gave enough information. Main motivation was to make video where they can show ParkTool (as they are sponsors) and this video did deliver solid presentation. Hambini is doing great job on his channel, but let´s NOT troll now every bearing video, which is not made by Hambini. Cheers.

For sram gxp it is applying preload on the non drive side, since that bearing is clamped by stepped axle and crankarm. in case of shimano hollowtech both bearings are floatiing so basicslly the whole axle could move left to right. its quite a different system.

Thanks for the video maybe you can share some light on my case I own a Rotor 3D Q ring compact chainset with 30 mm axle/spindle crank. The crankset/chainset I have is a combination with the Rotors 3D Inpower left arm meter (I guess the very first version). and I would like to swap it into my current bike. In any event, I would like to fit this crankset on my new Obrea Avant M20 Team D which has a shell of 86.5X46mm (I think the Obrea shell is called BB 386Evo) but these dimensions I have mentioned, I got from my bike shop mechanic who tried to fit it on and he said the crankarm is rubbing against the shell cups. He couldn't figure out if there is an adapter that can do the job and fir the two together. I wonder which type of adapter I'll need in order to fit the two together. if possible I'll be very happy if you could assist me with this.

Wow looks like Ollie has been working out😂 Is it just me or am I really seeing Ollies biceps😂

You could have used some shim's to convert GXP to BB386. Cheaper, faster and not worse than GXP.

Would the same apply if I wanted to install a Campag Super Record crankset on my 386evo frame?

If I have few bikes with bb30 and I am going to purchase quarq, can I use bb30 to gxp adapter?

how well should a new bb spin? should the new bb have any noise? will it be tight cause its new then loosed up and spin more freely? i just installed a pf gxp bb and it seems tight and has light click noise, normal???

Or, alternatively, who wants to swap between one crappy press fit standard and another. The first five minutes show how much is wrong with press fit.

the key to all maintenance: passion and smile ;-)

If the bearing in the crank push fit side fails how do you remove it without damaging the housing?

Ollie...you can use the formula torque equals force multiplied by distance from axis and hang appropriate weight by measuring the length of that bb tool

Did you take the crank out to put the chain on at 12:33 ? Did you think we wouldn't notice!

What's the value of the tapered spindle?

Oli, why do you need to use a bearing press tool to install the GXP BB, when you could screw the two sides together (one to the other) to bring them together and into the frame? I ask because I’ve got to install a PF30 BB soon and just planned to screw the two sides together to meet in the middle, as I don’t have a bearing press.

I have a raod bike with a 135mm qr OLD Shimano rear axle and I changed the 2x setup to Sram Rival 1 (BB30). I am a bit confused about the optimal chainline. I found out that the Rival 1 cranks have a chainline of 45.5mm (Some other sources state 47mm. I don't know why). I believe the optimal chain line for 135 qr is 49mm. I am shopping for chainrings and am thinking about buying a 3mm offset chainring instead of the 6mm one I use atm. This should move the chainline to 48.5 (or50) which should be closer to optimal 49mm if I am correct. Please help
