Re: Chains n' stuff

9 March 2015 - 11:41am
I have a chain gauge but I get conflicting advice as to what they are actually measuring. Some say stretch some say what they are actually measuring is wear. Either way the chain is definitely longer and more flexible so I guess it is a bit of both. My dilemma with chains and wear is this. Change the chain regularly before it stretches too much and wears the cassette out or wear both together and then replace them at the same time?

I had this dilemma with my road bike last year when I tried to change the old chain for a new one. Trouble was when I put a new chain on the old and slightly worn cassette it started to slip . So I put the old chain back on and my intention was to continue to run the old chain on the old cassette until that started slipping then change the whole lot together. (New chain, new cassette and possibly new small chain ring on the front).

A year on and the old chain and cassette on the road bike are still working fine although the chain is now very worn (the larger of the chain gauges, 1.0, now fits comfortably between the teeth) and the indexing is a little sloppy. I am intending to do the first leg of LJOG this summer (Lands end - S Wales) and after the chain broke on my MTB the other day was wondering if I shouldn't just replace the transmission on the road bike now and have done with it. MTB chains take a lot more strain that road bike chains but there are some pretty steep hills on the N Cornish coast.

BTW I have changed the chain on the MTB for a new one. If it slips on the old cassette then that will get replaced as well.

As a chain wears the links get thinner and thinner making failure more and more likely so time to bite the bullet and splash the cash me thinks.
Or you can just take a few powerlinks with every time you go out, and see how you get on? I guess there's a fair chance it will break again soon, but maybe you can put off replacing it all for a bit.

p.s. sod's law says that the chain will be fine until are in a hurry to get somewhere.

p.p.s. I would probably replace it. Or at least order the bits.

Stretch is the best measure. A £10 chain gauge is a great investment.

I'd vote replace it all now - it'll feel so much better and if you don't it'll probably break again anyway.....just at the worst moment.

Chains n' stuff

Out on my mountain bike today and the chain broke. Now the transmission on my MB is worn make no mistake. The chain has more flex in it than a snake and makes a lovely scrunching noise when it does with all the grit it has picked up out on the trails. The rear block has sharks fins for teeth and I am getting a certain amount of "chain suck" on the group set at the front. But I was hoping to get a little more wear out of it before replacing the entire transmission at £+++

My question is this. If I stick a power link in the chain am I asking for another long walk home or should I bite the bullet now and replace the entire transmission and have done with it?

Generally I agree.

Whilst accepting what you say about the old lady, my sympathy is limited. Quite simply this is an example of how cyclists are singled out and treated differently. Every Tom, Dick and Granny feels entitled to lecture cyclists about what they ought to be doing, usually (as here) from a position of complete ignorance. UK road conditions being what they are she will have experienced genuinely dangerous driving behaviour but I can guarantee that she would not feel the need to educate a car driver she anticipated was going to misbehave. It is socially acceptable to do so to a cyclist. Bad drivers are seen as individual bad apples, bad cycling is evidence of the failings of all cyclists.
I don't get everyone or anyone lecturing me on my riding behaviour.Unless I've been skimmed past and catch them up at the next TL and have a word,they usually claim I should get out of their way effectively,to which I usually explain,somewhat forthright,as to why I won't be.
IME little old ladies get some leeway from drivers,I've even experienced drivers stopping to let old folks cross the road in heavy traffic situations.
I've also witnessed idiots on bikes skimming past people old and very young in pedestrian areas(I'm in no claiming the OP was doing any such thing though)and as a result can leave a lasting impression on the mind.
Mrs R2 an myself have even,when walking on footway in a local town centre, been ridden at expecting us to jump out of the way by some yob on an MTB,he got a bit of a shock at my reaction,and I received a nods and words of agreement by other people walking on the same path when I told him where to go.
The difference between the UK and European cities and towns with pedestrian areas where cycling is allowed is like chalk and cheese IME,in that on the continent cyclists tend to be considerate and slow.
Here all to often they see it as an opportunity to practice their speed slalom skills,fag in gob,usually riding poorly maintained MTB's with one or no brakes and a red rusty chain.
It's one of a number of social problems we seem to effectively foster in this country due a total lack of responsibility by some,who seem to see their roll in life as trying to upset as many people as possible and a lack of an effective policing to put a lid on it.

Sorry for the delay in replying I'd missed your post.

Let's tackle everyone who breaks the law whatever they're doing,but the dangerous one's need to have heftier penalties imposed upon them.

BTW, cycling is permitted in many "pedestrian" areas. If cycling is prohibited there should be a no cycling sign or no vehicle sign (red circle with nothing inside). Cycling is perfectly legal in pedestrian zones where there is only a "no motor vehicles" sign (motorbike above a car inside a red circle)
But not many people know that,and in the case of tempsperdu's encounter with the lady I have some sympathy with her.Being small and old she'll more than likely feel vulnerable and UK society being what it is,she's more than likely experienced the yob on a bike riding far too quickly through crowds,so needed to make her feelings known.
FWIW last summer Mrs R2 and I were on the tandem on Morecambe prom(wide shared use)we'd ridden up from Glasson Dock,unbeknown to us there was some kind of 'do' on and it was packed with people dressed up in various forties and fifties clothes.
We rode slowly and considerately through the crowds,and stopped at a vacant bench to take in the spectacle,we were amazed at the number of cyclists of all ages carving their way through the crowds in what I would consider a dangerous fashion.
So I can see a little old lady's point,it's the few idiots(once again)who spoil it for the rest.

Do you guys have a gpx of the route. I'd like to try it myself in the next few months. I did half of the wales coast to coast yesterday, before being taken away in an ambulance

Re: MTB C2C Ravenglass - Ravenscar

I've not hired a van for a good few years, but I think I paid about £150 for a long weekend for a great big Peugeot hdi, think tranny Van but a bit bigger, seats 3in the front.

Might be worth looking into. Remember to factor in the diesel cost.

Edit, didn't read the OP was going coast to coast!

MTB C2C Ravenglass - Ravenscar

11 February 2015 - 7:13pm
Hi all i am looking into doing the MTB Coast to coast trip from Ravenglass to Ravenscar and am looking for any travel information that anyone has experienced. me and 2 friends will be travelling from Sheffield to raven glass and Ravenscar to sheffield. I have looked into trains and they are around £60 per person each way and although there is no charge for taking the bikes they only allow a certain amount on at one time and its a first come first served basis. as there are 3 of us i don't want to risk not all getting the same train so I'm hoping that someone can help with any suggestions/advice.

Re: Heading for Exmoor - footwear required

Thanks for all the suggestions.
Dartmoor is also an option for me, probably taking my tent and, maybe, the train as far as Totnes and setting up a base camp. That worked well for me last year at Builth Wells.
As for the footwear, I'll probably go for waterproof, lightweight boots and keep my Brashers in reserve.

I know people who walk rough terrain in trainers and others that will only do the same walk in three season leather boots you might need to give some thought for what will work for the type of walking you do. There may have to be some compromise. Hope this helps.
This is the main problem with cycling with boots, I would say that up too two - three hours or 30 miles you are OK its after that when the lack of free movement in ankles will affect your lower legs / knees, but how hard you push also has bearing, so if you are taking it easy on the cycle is probably best bet.
Flat pedals, even without clips, with boots.
If you take walking gaiters they with add waterproofness to boots and importantly add some perceived stiffness to boots which is what you need unpathed walking.

If you are sticking to track and paths with out much on your back then walking shoes would be OK but if your packing 25 Ibs plus and walking off path then boots are mandatory, if you don't want sprained ankles.
Good luck, as said it depends on the walking your going to do.

I walked this walk the other week and am here to report that the marked paths were for the most part, little streams. Armed with that info, you may choose to take with you, your most water-proof option...Dunkery Beacon.jpg

Love them or hate them....



Shimano MT90

I do a lot of investigation of barrows, stione circles and churches, so I find these a reasonable compromise between a walking boot and a cycling shoe

They are good at both tasks, but not perfect

A little heavy compared to shoes
