Re: Schwalbe Big Apple 26in tyres.

Thread resurrection because this comes up on Google when I search for reviews of these tyres.

I have 2" Big Apples on a fixed bike. The sweet spot is about 60-70 psi. They roll a bit better at 80, but they are harsh and it is defeating the purpose of them.

Much below 60 and the bike bobs horribly on steep hills. Less of an issue with gears, but the low cadence/high welly factor of fixed does them in.

Fixed requires you to keep rolling on a hill, or you stop. These become so draggy when they bob as to make me defeated by hills I can normally get up fine

I have run them down to 30 psi on icy roads, and they excel on the flattish.

Re: Chain Reaction Cycles

I bought a hydraulic disc brake, hose and lever from them in late 2015. A couple of weeks ago the lever started leaking fluid and the brake stopped working.

I sent them a warranty claim by email and they sent be straight back a brand new replacement of all three components, gratis, without any need to return the old ones.

Excellent customer service.

Re: Carbon forks, when to replace?

On the grounds that to make a Ti fork as non-noodly as a steel one would require more mass of material than a quality steel one.

There may possibly be a colour differential at night but there will not be during the day, a BS quality light just doesnt knock out enough light to be seen in daylight diffused by fog.


Dead right. You almost rear-end someone with a "normal" back light by the time you see them in fog. Cars without fog lights can be invisible in thick fog too.

Re: Carbon forks, when to replace?

Tubes in frames are in triangles. Supported at both ends

Steerers and fork blades are supported at one end and have an oscilllatory load at the other. Different kettle of fish.

Re: I'm not not normally worried about having the latest fad or technology but .......

Nexus 3s seem to be pretty reliable. The 8s and 11s need fuss over cables and rotary couplers and protection from ice...and oil baths.

I've used most of them over the years, broken many of them, and never found one that is genuinely minimal maintenance and reliable in the way that fixed is

Unless you actually break a chain or tear the sprocket apart, it just works. Always. In all weather.

Re: Cycling in fog ?

well, I doubt I'd opt to ride 15 hours in thick fog for fun*, but for the hour commute I would (do) just put the bright lights on and get on with it.

High intensity LED rear lights have been a game-changer for fog. I can remember about 25 years ago being on a club run and being caught in fog. It really didn't feel same to be on the roads since I couldn't see the bike in front, even with lights on (feeble glows in those days)

One of my most enjoyable rides was to Newbury Station down the Lambourn Valley in early morning freezing fog. I had a Goretex jacket on so was toasty-warm, but I arrived entirely coated in hoar frost from hear to toe.

* edit: mainly because it gets really boring

A Middleburn Cable Oiler is exactly what you describe.

But if you have to force in lubrication before each ride, you have turned a low-maintenance hub gear into a high-servicing item.



quite

I've followed a trajectory of derailleurs -> hub gears -> fixed.

Hub gears should be (but in practice really aren't) almost maintenance-free and reliable. They're almost as much a delicate flower at the top end as a derailleur. A basic Shimano Nexus 3 is about as close as I've found to bomb-proof, but it is still requiring of more faff than I can usually muster. So fixed it is, and has been for several decades.

Re: I'm not not normally worried about having the latest fad or technology but .......

Alfines and kinked cables don't play well together even after the cable is straightened. Unless you can get the cable entirely straight and kink-free like new, which I never have, it adds a degree of uncertainty to the gear shift. Time to change the cable if it's kinked.

Since supplanted by an ebay Rogers

Both are single wheel drive, and on the hills round here they just flounder. Lean back enough to keep the wheel down and the front crabs into the ditch. Sit up a bit and the drive wheel spins helplessly. I rode this one a lot on flatter lands.

Re: dont wine bottles use corks anymore?

Cork causing flavour problems is an issue with rosé wines. We drink a lot of rosé and it was affecting perhaps one in 3 or 4 at one time. I've only ever experienced it once or twice with red and I can't ever remember it with white.

I do like a cork, having said that.

Re: Carbon forks, when to replace?

Dave's right that for an urban cyclist, the risk associated with forks failing (unless you don;t listen to the creaks and clicks) or unless you hit something and keep riding the same forks) is less than being taken out by a car

My riding is mostly endless miles of mostly-empty roads. certainly when audaxing, equipment failure becomes a bigger risk. Probably less risk than dozing off on the bike though...or in the car on the way home.

It's entirely incorrect to suggest that it shouldn't be run fixed though. I purposely don;t use a lockring on my fixed bikes to prevent damage if the chain unships at the back. I've never unscrewed a sprocket by leg force.

Looks like you strip the teeth instead. :D


:)

Indeed. I rode back from Bolton Abbey to Leeds on that. I thought it felt a bit rough...

That was 25 years ago. I am older, possibly slightly wiser and certainly more careful about such things these days.

Re: Carbon forks, when to replace?

[quote="531colin" why would I go looking for 1" steerer in carbon or alloy when I can have 1 1/8" to 1 1/2" tapered steerers with a greater margin of safety, and no disadvantage for my sort of riding?
.[/quote]

Why not indeed, on a new bike. But lots of bikes were sold with 1" alloy steerers. The answer may be to replace them with threaded steel ones for future-proofing; even 1" threadless replacement headsets are not that common nowadays.
