London Fixed-gear and Single-speed

No, unless the original spokes are already too short.

poo :( I'll have a look under the rimtape to see if they are.

And sorry that was lazy of me

If you can't see 2mm of unused thread poking out of the nipples, it's not going to happen

:(

Is there anywhere decent to leave a bike around London Bridge for the day? Have vague memories that cycle parking round there isn't great. (This is for today so the bike park isn't an option)

Got an English Miche Primato BB in my hand. Has 110 etched on it but measures 107mm.

What length is my spindle?

In which case, as long as the printing is over the clearcoat, try dipping some masking tape in a dish of granulated sugar to make suger-sandpaper. This will rub the printing off whilst polishing the aluminium. It works perfectly on SystemX seatposts.

Good advice, but it's on black anodised aluminium. For everyone's future reference, it's definitely the acetone and not the scrubbing that gets the decals off. I've worn through a bit of the anodising trying to scrub them off too dry - just soak the fucker in nail polish remover an they basically melt off.

Bike park is closed now in any case, Thameslink have killed it to make way for a new station entrance to London Bridge and believe that more racks by the station platform are a suitable alternative.

The sheffield stands by Southwark Cathedral or the opposite side of Clink Street are ok-ish, lots of tourists and far enough away from the station to be not totally filled with chancers. The Clink Street racks are directly overlooked by 3 restaurants with big glass windows, too.

Did Thomson ever do an OS stem with their old-style concealed steerer clamp? I've got a new X4 and I don't like it as much as my old Elite :(

If it's 107mm long, the length is 107mm. I'm guessing the exemplary QA people at the factory making them didn't think it was worth their bother to stop using the cartridge shells etched "110-ISO" when they changed axle suppliers to a factory providing 107-JIS axles.

Miche. Nuff said.

My bike has a full carbon frame and a carbon seatpost.

Where am I meant to clamp it? I'm getting fed up of not daring to use my workstand with it...

How do you say Miche, when no ones listening?

Mee-kay

I thought they were French, been saying it meesh all along...

I'll carry on saying meesh.

M'kay

"Cheese"

couple of pages late... but most pharmacies will sell you straight acetone.
lighter fluid is better for cleaning off most stickers etc

What Reynolds tubing does Columbus SLX compare to?

I use cellulose thinners as I usually have a bottle knocking about. Doesn't harm anodising dissolves most paint/printing.

Do's anyone know of 'Hoosier' bicycle tyres? I seen a picture in the net but can't seem to find them anywhere.

^^ Post what 'you seen' - Hoosier only seems to make tires for gas and diesel powered things.

I stand corrected - and slowly back away.

Hoosier make drag racing tyres (that I am aware of), I reckon that those decals have been applied in homage as it were.

Or just as likely that is a motorcycle front tyre on the rear.

MBike tyres arent the same size...

That needn't be a bicycle rim, does have pretty thick looking spokes.

Through closer inspection, its possible the decal could have been added. But i would I would like to locate some if they do make them.

Hoosier do lots of tyres for speedway and drags. Not sure about this. I reckon just painted on.

Basic bike mechanics. Pretty embarassed to ask TBH. But I'm going nuts.

Installed a new Veloflex Master 23, on a well used (but never braked on) cxp33, with veloplugs, on the back of my fixed.

First time with a latex inner. Got it to 80 PSI, then after 5mins the inner blow out the side. Figured it was installation error.

Second time with a new latex inner. Got it to 60 PSI, all well. The next day I topped it up, and it went bang again in the process.

Last night I chucked the spare butyl inner from my saddle bag, and gave it 50 PSI. Came down this morning and it hard blown over night.

Pretty sure the veloplugs are installed tightly, although they where ripped out when I looked this morning. So it has to be a faulty brand new tyre, or a faulty old rim. If I get hold of a new inner I may re-install the tyre, moved 90 degrees around the rim, and see where it blows.

Which is most likely at fault here? Brand new Veloflex, or used cxp33 with pristene sidewalls?

PS.
fucketyfucketyfuckety!

ground up have made some prettyawesome bikes in their time
the fixedgeargallery annual winner from 2008 or so was a great rat track
beefy aero raw metal full of win

did you talc the inner tube before insertion? they are notorious for pinching when being installed, talcum powder can help with this

otherwise it sounds like there is a sharp bit, have all the tubes burst at the same point?

Cant feel any sharpe bits. I use latex inners for all my skinny tyre needs, so I'm pretty good at installing them usually. I'm going to mark the point tonight, but I'm pretty sure its the same spot. Actually stood watching the bead separate, and the tube slowly start spilling out, before releasing the air. So its definately something to do with the tyre/rim interface.

FFS!

On new rims, tyre explodey business if often down to a bit of weld that hasn't been machined out of the inside, just under the bead.



I can imagine a very small bit of weld, or even just road gunk, might have been lurking there for a long time waiting for a sensitive tyre.

Definitly appears to be something like this. The rims have been fine for a few years. Plus the tyres are brand new.

I'll check tonight. Cheers.

Sounds like the bead isn't seated properly on the rim and/or the tube is trapped under the tyre.

Can't imagine how else the tube could lift the tyre otherwise. Possibly the new tyres have a little kink from storage.. You definitely need to be noting where they blow each time.

I know you know and do this, but i) put a little air in the tube before fitting the tyre; ii) halfway through inflating the tyre go around the rim and squeeze both sides of the tyre twixt thumb and forefinger to free it from the rim and ensure it is properly seated; iii) compare some constant detail around the tyre with the rim to visually confirm it is evenly seated.

Check the tyres really carefully too, even if they're brand new blowing them off can fuck the bead.

thought this may have been the cause of blow-out number two. As I left one side of the bead fitted, chucked in a totally flat inner, and pressed in the remaning bead. Bad technique. But I was looking after the kids at the same time.
Nothing visible. But the bead isnt at prominant as I'd like maybe.

Going to have one last attempt at this. Checking everything. Marking rim, and reversing the tyre (which will mean switching my sprocket over, as I'm anal about these things).

Cheers folks

Start here.

I'm looking for some chain ring bolts that have each side as an allen key rather then one side allan key and the other flat head... Can any one help out?

.

Thank you!

On the inner tube, where abouts is the hole?

does anybody know where I might get hold of replacement cups for a 10 speed campag record cartridge bb?
