If they do, then nip to a workshop to have it tightened, unless you have a cassette tool and chain whip.Ĭhain is just really dirty: A dirty chain will be clunks and inefficient when shifting – if this is the case, follow our chain cleaning guide. This is easy to spot – grab hold of the cassette, and wiggle the cogs left and right – they shouldn’t move. This will be apparent by eye – you can bend it back yourself, but be very, very gentle- and if you’re at all concerned, ask your local workshop for help.Ĭlunking when changing gears could be rear gears in need of indexing: This noise will become familiar once you’re used it it – it will only happen when you try to shift, and will be a series of clunks and winges from the chain, which will probably then fail to move into the next gear as requested – in this case, the rear derailleur needs adjusting.Ĭlattering could be a loose cassette: If this is the case, you’ll notice a clattering when you ride over uneven surfaces. Jump off the bike and spin the pedal, if this is the cause you’ll see the chain very close to the piece of metal that shifts it between chianrings.Įither the front derailleur needs adjusting, in which case follow this guide, or by your derailleur is bent. Diagnose the noise your bike is makingĬonstant grinding noise could be chain rubbing the front derailleur: If you’re chain is rubbing on the front derailleur then the noise will be constant as long as you’re in the big chainring. WARNING: Fixing the bike clerking sound required technical knowledge and proper bike tools.Noises coming from the drivetrain are very common, and could have a number of causes. If the creaking sound does exist, most like the bb cup / bearing parts have worn out if the pedals / cranks / frame bb are perfect. Certain wheel hub is using sealed bearing, all we can do it re-lube the bearing and realign the wheel rim on bike.Ībove solutions may temporary solve the creaking sound from frame. However, if there is possibility of loosen bearing at the rear wheel hub axle. Sound exist from rear wheel could be due to the new spokes tension. Your need to have a BB tools as following to re-tighten the BB that attach on bike frame. Else re-lube the bearings.įor BST (British Standard Thread) type BB as shown above. Turning the bearing, if there is “rough” turning, replace bearing is required. Tools: Allen Key Recommend Torque wrench (suggestion torque 8-9Nm)įor BB30 / BB 386 model / etc, all you need to do remove the crank arm components and check the bearing condition. Solution: Re-tighten 5 allen bolts on the chainrings Non-hollow crank arm tighten the 7mm / 8mm allen screws on both left and right arm. If you can duplicate the sound and feel it, its an indication of an issue within the BB or crank. Then put a hand on each pedal and put body weight on it to simulate the load of pedaling hard. NOTE : Hollowtech II crank just retighten the BB cover (5) and allen screws (6) on left crank arm. One thing thats helped me narrow a creaking problem is to flip the bike over and remove the chain. Tools: Allen Key Recommend Torque wrench (suggestion torque 12-14Nm) Solution: Re-tighten both Left & Right crank bolts that attach on BB NOTE : Tighten Direction L – Anti-Clockwise, R – ClockwiseIf the clerk sound exist, change another pedals and try. Last year, more than 2.
