Question 1

On my brake levers, there is a Philips screw sticking out, just below where the cable comes out.

What's it for?


Question 2

I have centre pull cantilever brakes, they are rubbish - whats the best brake shoes? ( I need the type with a plain centre post)

OK - now you've mentally sold the family silver to fund a new treadiron, back to reality...

The wee screw is to adjust the amount of travel on the levers. If for example someone with small hands needed them set closer to the bars.

Brake shoes / pads are much of muchness really unless you go spending fortunes. More important is to ensure the wheels and indeed the surface of the pads are free of grease or oil. Bit of meths on a cloth will transform them.
 BiCycle questions. - Zero
The reason for the question is that Nicole has bought a nice light (aluminium frame) hybrid step through bike and wants to go riding.

The Zero jalopy has been dragged out of the garage, and cleaned, serviced and adjusted, but despite setting up the shoes correctly the brakes are crap.

If those tyres are cracked replace as a blow out on cornering and you end up in the hedge is not pleasant.

Brake blocks replace after 3yrs and clean up the rims with wire wool & de grease.

Spray chain lube on the chain after a ride let it soak in and wipe up after it drips.

Don't use a pressure washer near the crank as it forces water in bearings.
 BiCycle questions. - Runfer D'Hills
If he's not been on the thing long enough for the brake blocks to perish he's not going to be going fast or far enough to shred his tyres. It his um, "saddle contact area" he's going to have problems with first !

Agree about the de-grease though. Meths is best.
 BiCycle questions. - Bromptonaut
Posting from a tent in Provence so absent my usual reference sources but.....

My beloved Dawes Galaxy has old fashioned canti's. Setting them paralell to the rims in both aspects with a touch of trailing toe in is a nightmare job. Any deficiency is tempered by making sure the cable is AOK. Outer and inner both free of corrosion and sufficiently lubed without too much grease to attract grit etc.

Best shoes are fibrax, Aztec or Kool Stop salmon

Actually yes. Get some on the chain and all the ball races if it has been standing. If you had a bike rack you could attend to that with the bike elevated but of course you don't do you?

Yeah only us real men who havent smoked for a few years can handle a real mans bike.
 BiCycle questions. - Cliff Pope
Are the brakes set so that you are getting maximum leverage from the cantilever?

If you picture a crank lever with a rod or cable attached, you get maximum leverage when the cable is attached at 90 degrees, ie on a tangent to the circle formed by the radius of the crank. If the crank is angled too early, or too late, in its arc of movement you are wasting most of the effort.

So adjusting the length of the bit of wire joining the two brake cranks is as vital as the main cable adjustment.

Yer done that in combination with moving the shoes in and out, to get the maximum effort.

Still crap tho.

Of course I don't! Mine is perfectly functional and mainstream, nor am I jealous that she has a wizzy shiny brand new one:(


 BiCycle questions. - Iffy
Side-pull brakes - trademarked V-brakes by Shimano - are cheap, simple, and work a treat.

I'm guessing converting Zero's bike would be more trouble than it's worth, although he would need do only the front.

Seems to my eye to be a well made bike, with good quality parts, (the exception being the wheels)

As for me, despite Humph trying to strip my wallet down the bike shop, I dont need another bike, I just need to get the brakes working.
 BiCycle questions. - Iffy
...Nicole got one of these...

Looks like a decent bike for the money.

Mostly branded components, which is always a good sign.

Interesting you comment on the wheels, which are described only as 'alloy'.

Hard to tell from the pics, but another sensible upgrade might be the saddle.

 BiCycle questions. - BobbyG
Humph, don't want to hijack this thread totally, I have been using my bike for commuting for a few weeks now, much to my, and everyone else's surprise. Using it in the rain very quickly gunges up the bike with grit and stuff that lies in the edge of the roads.

Planning on stripping the bike down this weekend, degunging and relubricating but can you suggest a cheap way to make a stand to hold the frame? Don't want to fork out money for an off the shelf , purpose built bike stand.

Is there a cyclists "insider" trick to hold the bike for this purpose?
 BiCycle questions. - Runfer D'Hills
Yup, make a simple double A frame stand out of scrap wood. Bit like a very primitive "workmate" bench. Attach two crossmembers which fit under the cross bar and hang the bike on that. If you put a flat top on the frame as well it's somewhere to stash the tools you're using.

Alternatively, find a second hand car rear mounting bike rack at a good price and screw it to a suitable wall in your shed / garage....

:-)
 BiCycle questions. - BobbyG
Cheers for that, still have quite a bit of wood lying around the back, will give that a go tonight!

Oh and can I just say how much I hate those bike tyre valves that are not the same as car valves. Can never remember their name but totally pointless and a pain to blow up...

Feel better I got that off my chest......

Schraeder...no Presta !
Last edited by: Humph D'Bout on Fri 5 Aug 11 at 14:58
 BiCycle questions. - Iffy

Presta, sometimes known as 'high pressure'.

The car-type ones are Schrader.

I agree, never seen the point of Presta, but someone may be able to enlighten me.

 BiCycle questions. - Manatee
Presta valves are good because the screw holds them shut and they don't leak.

The advantage of the Schrader is that your car airline fits it.

The one with little going for it is the Woods valve which I think has died out.

Thanks.

I can see a valve which doesn't leak would have its advantages.

You can get self-healing inner tubes now too. "Slime" are the best known brand. Bet you're all excited to know that?
 BiCycle questions. - BobbyG
Zzzzzzz is that just for BMW and Mini bikes????
 BiCycle questions. - BobbyG
I have done 200 miles over 2 weeks on my boke with Schrader valves and the tyres are still pretty much rock solid.

Every Presta valve I try and pump up I either seem to break the screw bit off or the tyre goes flat instantly.

Give me Schrader anyday of the week!
 BiCycle questions. - corax
When I inherited my Grandads bike the pads were shot to pieces and noisy. I got some of these - quiet and effective, but not quite as good when wet and raining. And clean off the old rubber on the rims.

Look at it this way Z. If you buy a bike now it'll probably be the last one you ever buy so why not have a good one?...just to re-awaken the frailty of life theme :-)

I mean. you probably don't want neighbours spotting you wobbling about on that old rusty clunker with no brakes and whispering things about "him having gone to seed a bit since he stopped working" now do you?
 BiCycle questions. - BobbyG
Humph, he is scared that if he gets too good a bike it might go faster than his car on that downhill stretch........ :)
 BiCycle questions. - Runfer D'Hills
Well, you might have a point and indeed if he did buy a half decent one and put it in the Lancer it might arouse suspicion. The local Surrey Fuzz might reasonably conclude he'd nicked the bike.

He's gone missing again mind. Not like him. Fallen off or down at Halfords? What's the betting?

:-))
 BiCycle questions. - Zero
The RF clunker is quite kewl looking its only 10 years old. Cleaned rims with car brake cleaner and new shoes.

And it was only 25 years ago that I was cycling 120 miles a week. There is life in both of us yet.

Edit, and yes just been to halfords for new shoes and managed to leave minus new bike.

Doesn't hurt to have a spare...I've got two "in use" and an old Pacific. One of the first "mountain bikes" ever produced. Never ride it these days so I don't know why I keep it. It hangs on the back wall of my garage. Daft really. Might suggest my lad uses it as a school hack bike when he's big enough. Fancy me a Brompton now for my days in London.

>>Hmm, quite taken a shine to this one

Be careful! It may well be a well respected old name, but it may count for nothing nowadays.

I bought a bike from Falcon. The gears would change of their own accord and couldn't be sorted. The tyres blew off the rims at pressure considerably below advisable maximum. They refunded me in full.

Anyway, the front mudguards too short! You'll get muck all over the crank and feet. I cut up a plastic milk-bottle to extend mine.

>> Anyway, the front mudguards too short!

MTB'ers like the up the back stripe of honour, and splattered feet and legs complement the look.

Don't try to understand them.

There is no difference in efficiency between Presta and Schrader valves, nor in the pressure they can withstand. Presta valves are used with rims which are too narrow for a Schrader.
 BiCycle questions. - Runfer D'Hills
A warning for anyone intending to hire bicycles while abroad. Traditionally bikes in the UK have their back brake lever on the left side of the handlebars and the front one on the right side. Most other countries have them the other way around.

I went on a mountain biking trip to the Alsace a few years ago. Didn't take my own bike and hired while we were there. It didn't take long to adjust but in a slightly frenzied "moment" whch involved a long very steep descent down a muddy gulley and a pop over a fairly chunky log half way down I instinctively grabbed the "back" brake to skid/scrub off some speed after hopping the log.

Except...it was of course the front brake.

Several unplanned things happened at that point. The end result was the end of the handlebar driving into my chest and cracking two of my ribs. This was inconvenient. not least given that we were a good 10k from anything resembling civilisation.

However, I expect it helped me not to forget in the future.

Traditonal Dutch bikes you had to brake by pushing the pedal back.No hand brakes.The first time my missus had a go she nearly ended up in a ditch.;)
 BiCycle questions. - Cliff Pope
I have an old Dutch bike like that. There is also a rod brake applying a block of wood to the front tyre. It is only meant to hold the bike steady while getting on. Applied while moving, it instantly locks the front wheel, with amusing results.

 BiCycle questions. - WillDeBeest
Curious - Mrs Beest's bike is a Falcon bought in 2009 and she's very pleased with it. It came from a proper independent shop that also sells much more expensive bikes to more serious bikers, so I'm guessing they did a proper job of setting it up. They certainly asked her to bring it back after a month so they could refettle it as the cables bedded in.

I also have two bikes that I ride pretty well alternately: one for shopping (it has mudguards and a rack) and one for longer, more rural rides. The rural bike is a Cannondale I bought 14 years ago in Austin, Texas, while I was working there for a spell, and it has the 'foreign' brake configuration; the other is UK-sourced, and I've yet to find the difference a problem. Perhaps I've just not been trying hard enough.
}:---)
 BiCycle questions. - Robin O'Reliant
Both my bikes are set up with the front brake on the left, it gives a wider bend to the cables for smoother operation and stops them rubbing paint off the headtube.
 BiCycle questions. - Iffy
Another thought on Zero's brakes.

The shoes should not be parallel to the rim, the leading edge should be a little closer.

This means the brakes are less likely to grab, and the braking will be more progressive, the harder you pull, the more of the block contacts the rim.

I'm not sure how this angle is achieved, but there should be a means of adjustment where the block is bolted to the calliper.

Bit of a fallacy that one, Iffy.

No matter how much you toe the brake blocks in within a couple of miles they will have worn themselves parallel to the rim again.

The fixings have an eccentric washer, that can be turned and tightened to achieve the required toe in.
 BiCycle questions. - Bromptonaut

The use of 'leading edge' needs care. While, with the bike upright. its the front of the block that needs to contact the wheel first that's actually the trailling edge in terms of the wheel's rotation.

I agree with Robin however, toe in does not help much in modulating brake force as the difference is quickly eroded by wear. It does however help the new block wear in smoothly and eliminates any tendency for them to squeal.
 BiCycle questions. - Iffy
...eliminates any tendency for them to squeal...

When I were a lad, some bike brake blocks were cut to form three or four stubby teeth.

On cars with disc brakes, if a customer complained of squeal, we cut a slot in the pad with a hacksaw.

It worked - sometimes.
