The PF30 on my Boardman CX Team has been annoying me for the last 2786 miles, creaking like a whatsit. The original lasted 7000 miles before rusty balls destroyed it, and since fitting, and refitting, and refitting again, I have never been able to get the new one to run quietly. After some...

Need some help on how I size these new fangled bottom bracket bearings for my Boardman SC Comp fixie. Checked on the usual online suppliers and no numbers match what I have on the original unit. This has lasted 7 years and has finally given up ! So, how do I size this lump ?

What am l doing wrong...l bought a Campagnolo bottom bracket as per the photo Italian thread 115mm spindle, for my Centaur triple crank. To fit my Italian Veneto frame, except that it doesn't ! I can't get it to even begin to screw in. Is it possible that the frame thread is English and should...

What type of bottom bracket is this how is it removed and will the shell take a standard replacement. It is in a Coventry eagle frame at the local junk shop?

I've got an old separate axle Athena level bottom bracket I'm wanting to use... the Fixed cup has flats for which I have a suitable spanner... the adjustable side has half a dozen small holes.... does anyone know which tool it is... I did see the UT-BB100 listed somewhere and I'm glad I was...

A bit of advice required please. Im guessing that the crank arm has worn from all the grit trapped between it and the bottom bracket.Never really noticed anything from cycling but the bottom bracket developed a really annoying creak in the last few weeks so I decided to have a look.Ive since...

Morning all, I picked up a SH triban 3 with 650 wheels for the wife to use on the turbo (and to try to tempt her out on the road with me when the weather improves). It's like new, itlooks like it's never been outside, but there's a definite wobble on the chain rings which is causing me some...

I am looking for the above. The length is marked at 121 A...........B..............C ====||========||===== A=32 B=55 C=34 Thanks

I have removed the bottom bracket, The cups look fine. but the spindle race is slightly pitted. I can not find a replacement on Ebay. The part is stamped 121-> It measures A=32 B=55 C=34 It also has 3 stars stamped on it So these measurements add up to the 121. Any ideas where these can be...

I'm currently running an Ammaco XRS700, crap bike, but it was free and got me into riding again so shouldn't complain. Its got the old fashioned square taper bottom bracket which had really stiffened up a few months back. On close inspection, the drive side cup was not sitting flush against the...

Without starting a storm of epic proportions, I am interested in what sort of mileage people usually get from their bottom brackets. The reason for asking is that I have got more than ever expected from my first bike so far and wondering if this is actually normal. I appreciate that this will be...

picked up a Merlin Axe which was advertised with a 105 5800 chainset. When it arrived I noticed it was actually a RS500 chainset. Merlin have offered to replace the chainset but considering this means spending £15 on a BB tool and not having use of the bike for a week or so (I still have my...

Has anyone had any experience of these? They appear on Ebay for about £9. Anyhoo I have bought one for my hybrid that I use for shopping. I figure that for that price I can afford to take a punt for this bike...

Hi, It started off as a sort of a click on each pedal rotation about 200 miles back, only when putting pressure on the left crank whilst rotating. I took off the pedals, cleaned the threads and reinstalled and it went away for a few miles. Started again and progressively got worse, with the...

Hi, Was looking at buying a reasonably priced torque wrench drive to do some component upgrades. Regarding external bottom brackets, they say tighten to a certain torque but my question is do you need a special torque wrench for components like bottom brackets or how do you use a basic torque...

Hi, I am looking into replacing some components to upgrade my road bike and have a (probably stupid) question on bottom brackets. There appears to be different marketing for different external bottom brackets, some just appear to be external and some are marketed as hollowtech and hollowtech...

Just wondering if anyone knows what type of press fit bottom bracket is fitted to a Giant Defy 1 2013 model, so I can get some prices. Cheers

i've just got around to removing and greasing the BB on my few hundred miles old Brompton. It's a FAG with plastic cups - the fixed cup side of which I've sheared off the outer portion: This doesn't affect the function, but I suspect it will be a hacksaw and hammer job to remove the remains...

New take off, in opened box. Campagnolo SC-S bottom bracket, 115.5mm English thread. Square taper. £20 plus postage https://iansattic.space/shop/campagnolo-sc-s-bottom-bracket/

Well hello. Having installed a new BB just 40 days or so ago an annoying and all too familiar noise appeared, the creaking of the left hand side of crankset. Truth is, I can't actually believe it has failed so perhaps it has not! I managed to take the left arm off yesterday and noticed that...

I had to post this because I am so proud that i finally after 2 hours of swearing and bashing I have got the seized bottom bracket out. Moral of the story never assume that the bike was greased before assembly.

My BB was starting to make a complete racket on the non drive side so I looked to get a replacement. I initially ordered a more standard Shimano Tiagra 4700 Bottom Bracket like so... But they made a mistake with stock and I ended up ordering a swanky black one.... A Shimano Ultegra 6800...

Today I have replaced the external bearings in my bb for the 4th time in 7 years at at cost of £22 this time! Really! Just a few years ago bb's were made of 'kin 'ard steel and had 9 softer ball bearings in them which normally wore out first, the bearing could be taken apart and cleaned...

I recently swapped out the stock BB from my 2014 Giant Defy 1 this week after it developed a creak, this is the first time I have had to do so in 6k miles of riding on the bike. I replaced the stock BB71-41B with a BB92-41B(BB86). The creak disappeared, for a whole 20 miles or so and has...

after my first hard winter on the bike a charge cooker 1 2016 , the Btm bracket needs replacing, has anyone any recommendations which will allow me to use the existing cranks( fsa comet mega tooth) And the rear hub looks like to needs replacing as the cassette has play in it ( is a generic loose...

The right-side crank on my trusty Spesh commuter snapped tonight as I was setting off at a roundabout (Sugino 52/42/30), and I wondered whether it would be better to replace the whole drivetrain, given the years of service I've had from it, or whether a new pair of cranks would be okay? I'm...
