Oh no! My chain just snapped IN THE MIDDLE OF NOWHERE!

....and it was the one and only time I didn't take along my chain tool. :roll: :!:
So I got my keyring out and this is how I got home:

Those 27 miles were not fun. Obviously, the keyring would get caught on the chainring so I had to pedal/back-pedal with my left foot the whole way. :?
It was the middle of nowhere between Alderley Edge and Macclesfield in Cheshire - so no chance of getting a taxi home! Had no credit on the phone to even phone one!
I won't be forgetting that chain tool next time!
Anyone else had any similar tragedies when out training? I don't think there could be anything worse than this! :oops:

Like those quick-release links you can use to get the chain off the bike easily? Or are you talking about something completely different?
When I get a new chain (which i'm doing tomorrow), will the old chain be of any use to me if I get into a similar situation? Could I use it for "spares"?0 -
Wasnt a KMC chain by any chance was it ?0

A club mates chain snapped about 20 miles from home, on the moors in a snow storm. Needless to say he was very, very cold when he arrived at home after being pushed all the way."A cyclist has nothing to lose but his chain"

A bit OT, but I am moving up that way probably next year, around Bollington area hopefully. What are the best clubs in the area, specifically for racing rather than cafe rides?-- Dirk Hofman Motorhomes --0

I always see The Macclesfield Wheelers out and about. Not sure what they get up to though as i've never been on a club ride. Probably gonna tag along this weekend though, so i'll let you know.
The Manchester Wheelers are around that area a lot too. Again, not been out with them though.0 -
:idea:
Good bit of lateral thinking Bhima to use the keyring to repair it - must have been a pain pedalling back and forth with 50cm of useable chain but at least you were moving. Did you get the tip off Ray Mears or Bear Grylls?0 -
Isnapped mine going up a tiny little rise once and fell breaking my elbow. There ensued a 15 minute wait for somebody to stop and help.
Good thinking with key ring though!"In many ways, my story was that of a raging, Christ-like figure who hauled himself off the cross, looked up at the Romans with blood in his eyes and said 'My turn, sock cookers'"

A spare speed link or whatever you want to call it is no good if you can't remove the snapped link.
Good thinking there though, i would have pushed it up the hills and along the flats and free wheeled dow the hills, personally.winter beast: http://i497.photobucket.com/albums/rr34 ... uff016.jpg

I've got a new chain now - and the spare links I took out when getting it to the right length will be useful in future...
Weird - the chain is skipping on the higher gears, especially when on the small ring (at the front) and especially when I put the power down...... This never happened with the old chain...? How has the cassette suddenly got worn so quickly? :? :? :? It doesn't even look worn though...?0 -

Haha! It was in the part of Alderley Edge with loads of forrest - I was literally looking for bits of stone/twig at one point! I was chuffed when I found some string randomly - although it only held for about 10 meters! 0 -
The chain and cassette wear together, if the chain wears too much before replacement, the new chain won't mesh with the cassette as it has worn to suit the old chain. With judicious chain changes many reckon on getting 1 cassette to last 3 chains, but you have to change them before they go too far.
I always carry a spare KMC link and a Lezeyne multitool that has a chain tool (it is a very small multitool, but the chain tool works well). A broken chain miles from home with no way to fix it can be very sad!0 -
Right! So I never noticed the wear before because the chain's wear counter-acted the skipping? I'll get a new cassette tomorrow - but, theoretically, if I were to leave it on, would it damage the chain and decrease the life of it? i.e - Should I replace the cassette ASAP to minimize chain wear?0

Not sure if the chain would be prematurely worn, but your sanity and safety would suffer with chain skipping. Some wisdom from Jobst BrandtBhima wrote:Right!

Skipping Chain
Skipping Chain Sprockets do not change pitch when they wear, only their tooth form changes. The number of teeth and base circle remain unchanged by normal sprocket wear. What changes is the diameter at which the worn and lengthened chain bears on the sprockets, making wear indentations at a larger diameter than a new chain requires. In practice, this amounts to a change of pitch, since the chain will no longer ride in the original valleys between the sprocket teeth.
A new chain often will not freely engage a worn rear sprocket under load even though its root diameter has the same pitch as the chain. This occurs because the previous (worn and elongated) chain formed pockets higher on each tooth (a larger pitch diameter) than an in pitch chain describes. This wear occurs because a worn chain rides high on the teeth. A chain with correct pitch cannot enter the pockets when its previous roller bears the previous tooth, because the pocket has an overhang that prevents entry.
Without a strong chain tensioner or a non derailleur bicycle, the chain has insufficient force on its slack run to engage a driven sprocket. In contrast, engagement of a driving sprocket, the crank sprocket, generally succeeds even with substantial tooth wear, because the drive tension forces engagement.
However, worn teeth on a driving sprocket cause "chainsuck", the failure of the chain to disengage. This occurs more easily with a long arm derailleur, common to most MTB's, that is one reason this occurs less with road racing bicycles, that experience a noisy disengagement instead.
In contrast a worn chain will not run on a new driving sprocket. This is less apparent because new chainwheels are not often used with an old chain. In contrast to a driven (rear) sprocket the chain enters the driving (front) sprocket under tension, where the previous chain links pull it into engagement. However, because a used chain has a longer pitch than the sprocket, previous rollers bear almost no load and allow the incoming chain link to climb the ramp of the tooth, each successive link riding higher than the previous until the chain jumps. The pockets in a used sprocket are small but they change the pressure angle of the teeth enough to cause skipping.0 -

Push it up to the top of the Edge and coast downhill to Macc 0 -
Cheers alfablue - it was a bit of a nightmare to get my head around that explaination but I get it now (after reading about 6 times!)...nickcuk wrote:

Would have cost more to get a taxi from Macc, plus it's not all completely downhill!
By the way, what's this doing in the Training forum? Didn't I post it in "Workshop"? :?0 -

Macc Wheelers are the local club. Large club with an active racing scene, both road and time trialing. Club runs at 1300hrs on Saturday, Sunday training rides during the winter and chaingangs on Monday and Wednesday nights during the winter, and Monday and Thursday during the summer. Club 10 mile TTs on Wednesday evening starting 9 April.0 -
Good point about carrying a spare link, so what link would I need with a Shimano chain?0

SRAM powerlinks work fine with Shimano chains (don't know about the others). Have also got away with fitting 9 speed link to 10 speed chain in emergency. Even if you carry a spare connecting link you still need a chain tool to remove the damaged link.0 -

Up the Irons !0 -
it happened to me last September. Returning home over the Denbigh Moors. I coasted downhill and walked up for about 2 miles to the village of Bylchau. Saw a chap mowing his lawn so asked if he had a pair of pliers to try and squeeze the link together. Luckily for me he was an ex cyclist and had a chain link tool in his shed. Between us we sorted it and I managed to ride the last 14 miles home. Always carry the right tools now though!Here's a box,a musical box. Wound up and ready to play.

How did the keyring get through your rear mech?0

After reading this I realised that I wasn't carrying anything for this eventuality! So in a panic I have bought some KNC links from Ebay.Norfolk, who nicked all the hills?
