Can you tighten a bottom bracket
Answered By: Rodrigo Torres Date: created: Jul 30 2021
There are special spanners you can buy for this or you can use an adjustable spanner to move the bottom bracket cup and a screwdriver tapped gently with a hammer to tighten the lock ring. You may have to improvise further with your choice of tools.

What causes a loose bottom bracket
Answered By: Bryan Flores Date: created: Aug 10 2021
Most surprisingly, what often sounds like a bottom bracket creak is actually something else. Most of the time, the true cause is a loose chainring bolt—tighten them up and that'll quiet most creaks. … Crank bolts: If your cranks move side to side more than 1/16 of an inch, you've found the likely creak source.

How do I know if my bottom bracket is too tight
Answered By: Adrian Perry Date: created: May 21 2022
If the BB is too tight, it will not rotate without grinding or feeling stiff. In fact, if you ever tighten an adjustable (open/loose) BB to an extreme, the BB will not move at all. If you diagnose this problem in an open/loose system, you must loosen the adjustable cup until the stiffness lessens.

Can you over tighten bottom bracket
Answered By: Anthony Henderson Date: created: Aug 17 2021
If you overdo this, you'll load the bearings such that they wear down faster. If you've overtightened this, you need to undo it. Same with putting the non-drive side crank arm (which is something like 15 Nm normally).

What happens if bottom bracket is loose
Answered By: Louis Sanders Date: created: Jun 20 2021
An open/loose BB will need its bearings adjusting (via the adjusting cup) or replacing. If you diagnose a loose BB in any other type of unit, such as BB30/90s and outboard bearing units, the first thing to check is the attachment system of the cranks and/or BB spindle.

How tight should a threaded bottom bracket be
Answered By: Steven Ross Date: created: Mar 17 2022
If your bottom bracket's threads are particularly tight, you might want to have the them chased to see if they can be freed up. Generally speaking, with bottom bracket thread, you don't want them 'baggy' and loose, or annoyingly tight, somewhere in between.
Asked By: Richard Mitchell Date: created: Aug 04 2021
Should bottom bracket threads be greased
Answered By: Michael Scott Date: created: Aug 06 2021
In the case of the bottom bracket, you will use the grease when you install it, whether it is threaded, press fit or similar, and in the same way when you install or clean the cranks. The point of contact of the cranks with the bottom bracket should be greased too.

What do I do if my bottom bracket is loose
Answered By: Jayden Nelson Date: created: May 16 2021
Firmly hold the bike steady and attempt to move the crank from side to side – in the opposite plane of motion to its rotation. If there is any play from side to side, the BB system is loose. An open/loose BB will need its bearings adjusting (via the adjusting cup) or replacing.

Is my bottom bracket worn out
Answered By: Joseph Rogers Date: created: Jul 03 2021
If your crank is wobbling or there's a noise in your bottom bracket when you're pedalling, maybe it's time for you to replace your bottom bracket. "noise from bottom bracket" can also mean loose chainring bolts or a broken frame, and is most often the former.
Asked By: Herbert Foster Date: created: Jun 17 2021
How often should a bottom bracket be replaced
Answered By: Ashton Collins Date: created: Jun 17 2021
There's really no periodic time period for BB replacement. You run em till they die. If the bearings are smooth without any perceptable play, then they are fine. When things eventually get contaminated (if they ever do), then you'll notice roughness, crunchiness or significant play in the bearings.Oct 18, 2005

Guest12 speed bike
What does a 12 speed bike mean?On the back, the 12-speed cassette starts at a 10-tooth cog, and increases by 1-tooth per cog. The overall result is that you can reach a higher resistance at the top-end, and your smallest gear is even easier to push.15 Sept 2021Which is faster 11 speed or 12 speed?Since the 12-speed cassette has the same total width as the 11-speed, the space between cogs is narrower. This leads to “faster” shifting since the derailleur doesn't need to move as far to switch gears.3 Nov 2021Is a 12-speed bike good?And thanks to improved materials and tolerances, they're also much more reliable overall, even if they can be a little finicky compared to those 8 and 9-speed systems. 12-speed drivetrains pretty much killed the front derailleur as well, especially after 11-speed showed that maybe we didn't need them after all.16 Jul 2020Why is 12-speed better?Since the…
