I thought who ever had assembled this crank must have used a threadlock 622 loctite. When I leant on the bolt a bit to hard it broke. When I phoned the wholesaler to order a new one they said they had broken the first bolt they did as well. Thanks for letting me know guys!

Curious, all the Torx chainring bolts I've met have been T30.Xplora wrote:Go team I swapped a stronglight 36 chainring onto my crank tonight, torqued it up and everything I need a better quality T25 wrench though I don't think I worked out that the wrench fit the chainring bolts until I got the torque wrench onto it (better bits on that one )

Now, I live on some acreage, and the back shed where I work on the bikes is a bit of a way from the driveway, where I test them.
So, I tighten the chainring bolts.
Carry the bike and the bike shoes to the driveway, so my speed plays don't get gummed up with dirt.
Put on socks, shoes.
Test bike.
Creak still there. Fair enough.
Take off shoes,socks.
Carry bike back to shed.
Find out bb tool has been borrowed.
That's slightly inconvenient.
Go next door and borrow bb tool.
Discover bearing puller doesn't suit new crank.
Drive 40 minutes to buy bearing puller.
Damn. This is really annoying.
Pull crank
Unscrew cups.
Wipe out all grease.
Degrease bearings, cups etc.
Retorque cups.
Put crank in.
Retorque crank arm bolt.
Discover I didn't skewer chain when putting crank back in.
Obviously can't get chain on.
Can't believe I did that.
Deep breaths. Count slowly. 1, 2, 3, 4......
I don't have a missing link or a spare chain pin.
Pull crank.
Reset grease how I want it.
Skewer chain and replace crank.
Retorque crank arm bolt.
Carry bike back to driveway.
Put on socks, shoes.
Ride 2 metres.
Flat tyre.
Throw bidon into the side of the house.
Take off shoes, socks.
Trudge with bike to shed.
Change tube.
Trudge back with bike to driveway.
Put on socks, shoes.
Test ride.
Creaking noise still there.
Sit quietly thinking Zen thoughts for 10 minutes. "That which does not kill us etc etc"
Take off shoes, socks.
Carry bike yada yada.
TIGHTEN THE CRANK BOLT I #$&% WELL MISSED THE FIRST TIME 3 $&% HOURS AFTER I STARTED.
Carry bike, shoes etc etc ad infinitum.
No creak.
Should have been a 40 second job.
I do usually know what I'm doing.
No, really.
Weep silently while putting tools away.
Go get beer.
Forecast is for rain tomorrow.
Will take fixie instead.

On the 1st test run down the driveway, applied the brakes and shot the rubber brake shoe inserts straight out of the alloy holders.

I'm concerned about my crank bolts all of a sudden with this T30 talk (no play on words intended). Would explain why my alloy crank bolts don't look so flash now
Followed up yesterday's effort with a flat, and then couldn't get the bike going with a spare tube and a repair kit. NOT IMPRESSED.

One of my best purchases would have to be my 10mm ratchet spanner, only a little thing but it makes installing brakes that little bit easier.

Connected the cables and suddenly.... the cable adjusters have been left out I now had to release the cables (supposedly they cannot be re-used once taken out). Luckily, amazingly, I was able to refit the cable ends into the very small anchor bolt holes.
Now to check out the shifting. Twist...... won't move. The shifter simply is too tight to rotate. I re-read the manual, ran through the whole process. I took the EX box off to check the direct shift with a spanner. The gears do shift, but put the EX box back on and the twist-shifter will not move. I mull over this problem for an hour or two and posted questions on the Thorn Forum about the Rohloff. Turns out the spanner-shift should be very easy.... mine takes some leverage effort. Umm, something wrong inside the gearhub ?? That funny cog
I pull off the wheel, remove axle-plate's five hex-bolts and pull out the cog. The small one in the middle here:
It's asymmetrical. I flip it over and refit the axle-plate, mount the wheel, connect the EX box....... and the gears are shifting nicely. D'oh!!

Moral of the story, always double check which way you're trying to spin something.... lol.

Go to do my own last night, yep, put it on the wrong way
Thankfully I had a spare chain, just just broke the chain (in a different spot), flipped it around and installed the new pin. Now to buy a spare chain pin or two.

Hate to depress you even more but there were more than a few differing diameters of cottered axle made over the years. look out for older continental and Japanese stuff.ldrcycles wrote:I found out last night that there is more than one diameter of cottered crank axle, the british size which fits Raleigh cranks, and the ISO size which is, get this, only 2 tenths of a millimetre larger. I have Raleigh cranks so guess which size axle I have?
Not even going to mention cotter pin sizes....
