hi i need a chain ring fixing bolt

WELL LOCAL SHOP NO HELP not got anything , so i got a brake cable clamp bolt and filed corner off to slot it in and nut and washer on the outside so at least it is usable,

dimensions are:
overall length when joined together and tight on crank 12.6mm
shoulder of bolt part 8mm and
shoulder of nut part 6.85mm
silstar is the brand of crank

picture of crank on bike showing missing item at 4 oclock, also picture of the bolt parts itself

will stick it in wanted forum

well been out and checked it. the arms and guard ring are all one piece and the two chain wheels bolt onto the arms/guard ring combo
but just noticed one of the bolts is missing
you can see it in picture at 4 o'clock and outer chain ring !
i wonder if i can get another one?

some years ago i had a worn chain and sprocket set up on mountain bike , going up hill out of saddle pushing hard, chain jumped and i went out the side

cracked wrist and elbow. had to ride home a good few miles , hills , peak district, was like electric shock down arm every time i tried to use the brake!! then docs tors said i hadnt broke it , just a strain , carry on lifting things etc.
then a week later rang me up and said they had "looked at the x rays again and i had broke my wrist , come back" in took pics of wrist and elbow and said i had broken both !! all ok now though , new chain front and rear sprockets, cheers

i will take it off and see but i think the larger chain wheel is bolted to the guard ring and then the guard ring has fingers on it and these are also bolted to the arms on the crank . i will post some little pics if that is the case when i have it apart later today . if so i will l leave it as is till i get a better crank, thanks for replies

hi again,
thanks for the comments
if i unbolt it then the big ring comes off as well, as the big ring is mounted on it . i was thinking of cutting the guard ring off but save the bolts etc that hold the large ring on .. but hey i am trying to make it look more than it is so perhaps i should just leave it as is...or get some smarter cranks, the bike by the way is a 1953 king of mercia that i have just rebuilt and will strip down again and paint when i am happy with all the components
cheers

hi folks i am thinking of cutting the guard ring off this double ring crank and chain wheel.
any ideas whether i will weaken it too much and cause the chain rings to bend??

what do you think ?

edit ref notification

what length cranks are they ??

hi folks

with all the bikes going to fixed or single speed any one got a 6 speed freewheel 14 to 28 that they would move on?

for building up an old road touring bike

cheers

cheers mate

sheldon brown makes a good point about them and also comments that they might not do you any good in an accident like a blunt knife to the groin !!

i have a pair of shimano sis ones i shall try them

and i have realised i have a damaged boss on the frame the one just above bb on drive side that guides rear gear cable to the chainstay tube i shall have to visit mercian next week and see what they say

i am near derby anyway

yes cable stops but just wondering what was at the top end of the cables !!

its last reincarnation was as a fixed wheel track bike with one brake and 28 spoke large flange track wheel tubeless etc

i am turning it back into a road bike might try for some stem shifters if i can find some

hi folks
old mercian frame with bosses very near top of down tube

what are they for ?? stem shifters or bar shifters

it is a 1953 frame so not anything modern

@ wikey

Nice story but you should have gone M5 / M6. It would have saved you 80 miles ;)

yeh but givin my age away, not all the motorway was there then !!

although a policeman did try and send us on it at lancaster - youd think he would know better

yeh one for the grandkids later

"I need to hear jolly stories of your cycling exploits."

well heres one
when i was 16 my mate Tim and i were bike mad, belonged to cheltenham and gloucester cycling club.
in the summer his father died and at the funeral his cousin who was about thirty started ribbing us about cycling

tim's mum had invited me to join tim and his young brother and her on a weeks holiday in a cottage near stranrear in scotland
tims cousin knew this and said if we were so good we could ride there. tim said we would and then got over excited and said we would do it in 2 days. his cousin said he would bet us 15 pounds on that - a lot of money at the time. so a week and a bit later we set off from cheltenham on our dawes red feather 5 speed bikes. we pulled into kendal mid evening and had a meal at a b and b and walked into the town a little way and had a couple of underage beers

next morning up early back on the bikes , up shap and down to carlilse gretna, dumfries lockerby and that evening into stranrear or at least nearby where the cottage was . done in 2 days, 420 miles we got our money and we put the bikes on the train to go back home !!
