IT’S TRUE!
CCE is 15years old!

Today's rubbish attempt at assisting a fellow cyclist...
He was walking his bike along the A70 near the airfield. It turned out that his derailleur had broken off.
"I've got a chain tool," I said.
I do have a chain tool, but the pointy bit for poking bits out of the chain is missing. So I was not much help.
I will check at home first, otherwise I will order a new one.
So in changing an old cassette for a new one, I really struggled to get the old one off. Turns out that the cassette has bitten into the metal hub. This is on a fairly new (~3 month old) set of wheels. Did I do something wrong when I installed the cassette? Or should this hub made of cheese be sent back as not fit for purpose?
Cassettes that are a simple stack of sprockets, with spacers in between, rather than sprockets attached to a complete carrier, have a common tendency to cut into the trailing edges of the splines of freehubs. The problem is exacerbated when the freehub is made of aluminium, which is rather softer than the steel sprockets.
@Arellcat
Thanks. This is the damage.
My reference point is the previous set of wheels that I had for 2 years and which did upwards of 6000 miles before retiring. The old hub has hardly a mark on it.
I want to return the new wheels if they can't handle what they're designed for - carrying the force from a cassette...
Hopefully the links work...
I have a relatively unused wheel in the shed with a dug-in largest sprocket which I shall one day get round to removing, perhaps sometime around the same time I get round to finishing building the rear wheel currently assembled but untrued and untightened in the loft.
Had squeak on seat which on a recliner is intensely annoying. Solved that and then became aware of ticking noise from rear.
Suspected a broken link on chain and was right. As bike uses 2.5 lengths of chain I had enough spare and Bike Works have 2 x 12 Speed links for £7 which is pretty good I thought.
1 x 12 set up now 14 months old. Chain angle to rear cassette is very slight so surprised any plates are being caught - this one on outside too.
Three or maybe four weeks ago I set off home in the torpedo and found it strangely hard work. Halfway home there was a suspicious noise from the front end that sounded like a resident murine population having a party in my front wheel.
Turned out that 11,000 miles of Edinburgh's potholes and salt has killed one of the rims, with the spoke nipples pulling through. The loss of tension in turn caused other spokes to break. The brake drum thus went fractionally out of round, and jammed partly on, so the hub was now also full of brake dust.
Against better judgement I ordered from That Germany an identical replacement rim and some more spokes. Two weeks went by and I'd heard nothing. Then I discovered an e-mail in my spam folder, that said the rim was out of stock and in any case they recommended I not buy it because of acknowledged metal fatigue and quality control issues, and would I like to buy this or that alternative instead?
Well, yes, I would like, but that requires buying two rims and 80* new spokes to do both front wheels. And I suspect there will be no deliveries at all until the autumn.
All I wanted to do was rebuild the brakes.
* 72, with some spares
@Arellcat
Have some rims here. Velocity are only 32h and ICE Alex ones 36h.
@LaidBack
I've never seen wear like that on the outside of chain plates before. What causes it?
Usually it's because on many recumbents the chain runs inside teflon tubes, so the outside links of the chain get polished.
@LB, what width are the ICE rims? Ginkgo recommended the Alex MD25, which is a kind of heavy duty DA16. Our USAnian friends can pick up lovely eyeletted SunRingle Rhyno Lites for, like, 35 bucks each, but they're super expensive here.
@ iwrats - I have never had the plate ends snap off before on such a 'new' chain. 12 speed is close to limit maybe and has little leeway for mashing up gears. Generally if I had such a luxury item on my 'weekend bike' I would probably be happy. It is a downhill MTB item so oddly meant to be tough and disposable at same time! It does shift very well and allows a huge range of gears off 40T ring with 10-50T cassette.
I've used the Fuego to haul heavy trailers - once with two e-bikes on back - that will give chain a good work out. Gunge sits in chain tubes - upright cyclists always think the resistance is huge but in fact not noticeable.
@Arellcat you have loads of chaintubes but 'indoors' on Quest?
BLB Big Mama have best rim choice but they are expensive.
Alex 16 - Inner width: 16.3 mm
Outer width: 22.4 mm
Sun Rims are good - had on our first red tandem.
I proudly proclaim superiority with my tube free Fuego! In keeping with the thread topic I bought an air shock for it that is slightly too big, despite measuring the old one several times. Somehow I translated 150 into 165 in the time it took me to walk from the garage to the PC. Still seems to work ok although my current incapacitated state has left it as yet mostly untested.
@LB, if you have a couple in stock I might be interested. Are they tough enough, do you think? Kinetic energy of a velomobile can (unfortunately) be very high and most are using lighter weight BMX rims now.
The Quest's drivetrain does stay remarkably clean, and the drag from tubes isn't very high. I oil the chain about once every thousand miles, or whenever I remember!
@nobrakes - good to see you posting. Forum is a good morale boost in these times. Tubeless is a thread in itself. Yes both sizes of Fuego have different shock length but with your new super aero seat position maybe better to be longer.
@Arellcat - got one DA16 ICE X version can get another 36h . Eyeletted spoke hole rim would be better though perhaps?
My 'hack' Fuego has an old silver 20" DA16 front wheel and still ok. Was the front wheel of our yellow 20" wheel tandem from 2000. So 20 years old with older SON hub.
Tubeless as in no chain tubes :)
If the outer plates are continually wiped, would a chain tube work as a sort of cleansing tunnel on an upright, or would it just concentrate all the muck and gloop inside the links?
@NoBrakes - of course. In reclined cycling you can have both tubeless chain and tyres!
@wingpig - the gunge does settle between the plates. A Hebie Chainglider is liked by some. Plastic chainguard for standard hub geared bikes with close fit.
Last week when doing some TLC on our tandem I managed to lose control of my trigger finger and sprayed WD40 on the rear brake rotor. Oops. I then spent a good while trying to make sure the rotor and pads were completely clean before going out on it again.
Last night's ride - rear brake basically not working. Also seems to have lost its pull which suggests it needs bled (about 3 years since the hydros were last bled, I have too many bikes to maintain!). Not sure if it's an unhappy coincidence and the brake actually needs bled or whether I'm just imagining it and the pads are now completely contaminated with WD40. It has been on my radar for a while that the brake bite was diminishing. Hard to see the caliper movement when you're about 8 feet away at the brake lever and I didn't think to ask another member of the household out to the garage to lend technical assistance.
We do have a rear rim brake for the stoker to use as well, so we're still legal! :)
Not quite living up to your user name, then?
;-)
(Sorry. Had to be done.)
:)
@nobrakes - It's a heavy rig not to have two working brakes and one in reserve!
Hydraulics are better for a longer hose run they say but bound to get air in over time. Older UA cargoes suffer the same, their most common 'fault' - good news for bike repair shops though can be DIY'd.
Our cable BB7 rear is pretty puny on our version of that bike. Front hydraulic vital.
@laidback - hope the hack Fuego you refer to isn't my old orange one! :P That has many lovingly selected upgrades...
@darkerside - upgraded by you then degraded by two other owners!
Upgraded again now as 12 speed. Very nice steel frame and only 'hack' in the sense it has 20 year old front SON wheel and orange paintwork showing wear!
Note to self;
1) You cannot turn a square taper crank extractor into an Octalink one with a mild steel washer.
2) Measure the length of your bottom bracket before it fails and you can order one without having to take the cranks off at all.
3) Take a photo of your BB label whenever you have sight of it (initial installation, previous replacement) to avoid having to measure it.
4) Panic buy a couple of spare BBs and a square taper crank spider in 2013 when their ominous reduction in price and low stock makes you think they're about to be discontinued forever.
5) Print the photo on archival paper in case your SD card gets corrupted.
Have somehow forgotten how to replace disc brake pads. Made the tactical error of overthinking it while in a rush rather than autopiloting it out, and had to abandon attempt and run errand on a different bike.
My Octalink crank extractor has dropped. Stand by for a measurement.
Spent a good chunk of Monday fiddling around with a front wheel that I thought must, must have a flat spot. After all the telltale thump thump thump through the handlebars when traveling at speed does not lie?
Nevertheless, even after breaking out the dial gauge I couldn't find anything. Gave up and put a different wheel on.
On this morning's State Approved Exercise I found the real reason. Headset was loose. 2 minutes, fixed roadside.
The rim got a clean I suppose...
I lost all front braking on the way back to the house a couple of weeks ago. Thankfully I was less than a mile away and it was almost all uphill.
Taking the pads off it is painfully clear that I was late replacing them I put a screwdriver through one pad trying to reset the pistons such was the level of my neglect.
