so i just bought some stronglight cranks and i was wondering if you need an allen wrench or special tool to attach them to the bottom bracket

man anyone know where i can find the search link or use freakin punctuation or anything cool cranks cool

so you dont know?

I don't get the venom.

To the OP: If it is a new crank, you just need a large allen wrench (I think it is an 8mm). Make sure you snug it nice and tight. Then ride the bike up and down the block and snug the bolts again.

thanks a bunch! i was hoping that i could just use an allen wrench.

you got pretty bitter in two months

to op i picked up some stronglight track cranks about 6 months ago but had my LBS install them so all i can add is they're great have fun!

Note all punctuation except the exclamation point was removed for telix

yeah im really excited for these. ive been eyeing them up on the internet since i deciding to get my new bike and these are the last and final piece to complete it(replacing shimano 105 175mm). i picked them up at via on saturday. now i just need to get them on the bike!

aight, you need more than a pocket multi tool allen wrench. you need something a little heftier, something a little bit longer. i have absolutely no intention of trying to put on or remove my stronglight cranks (well, just crank now since i bent the nds) with a pocket, folding allen wrench. but luckily, i do have a nice bit fat long one, and it does the job.

fyi, they're called self extracting crankbolts. you tigten them, and it pulls the crank on to the square tapered bottom bracket spindle. when you loosen, it pulls them off. for other types of cranks, you need a crank puller, which threads on to the crank, and then threads on to itself to push the cranks off the spindle.

self extracting crankbolts are the cool.

I'm just a long-time user of a variety of forums and don't care for unformatted AOL typing.

learning new things everyday! thanks for the information!

the concept is pretty cool. i snapped the one that came on my sl track cranks though, and was worried that i'd completely screwed up the cranks. turns out they're just little inserts that screw into the cranks and they can be removed with a chainring bolt tool.

Hey, It seems that you can buy them for your cranks. Some made of Ti. Does anyone know if they can be used on all cranks?

well, when i took mine out the stronglight cranks had the same threading as regular square tapers. normal crank puller works so i assume the reverse is true, that you can screw the self extracting bolt into any crank.

You can use self extracting bolts on most cranks.

You need to make sure that the part which screws into the crank arm is nice and tight before you self-extract the cranks. If it isn't then you can strip the thread on the crank. That's bad news.
