Mechanics and Fixing Any Questions Answered

Anyone got any ideas about a replacement for this little fucker of a bolt, it is a ickle 6mm one, from a fork not a crankset. I can't find source for buying one online in the UK

All,

Can anyone out there help?

I'm looking at a pair of wheels on eBay. They would be an ideal second pair for my best bike but they come with a Planet X 11 speed Campag-compatible freehub. I ride on Shimano.

I have contacted Planet X in search of a replacement freehub but they've told me they're now discontinued.

Does anyone recognise the freehub and might anyone have an 11-Shimano replacement?

Thanks.

Not sure they're worth over £300 with postage and a new freehub if you can find one, bit of wear on what looks like a metal rim with carbon faring.

yes, these are worth half of asking price

My tubus duo rack is supposed to only be used with forks with inner and outer eyelets. My new forks I bought to go with this rack only have outer mid eyelets. Will I die?

Edit: doesn't fit anyway

My frame has a 31.6mm diameter seat tube, I usually run 27.2mm seatposts.
I'm looking at buying a carbon seatpost and I was looking to increase comfort/flexibility. My initial thought was that a 27.2mm seatpost with a shim would be more flexible than a 31.6mm seatpost, but the retailer seems to think a 27.2mm seatpost would be stiffer.

What do you guys think?

The retailer has watched too much youtube. A 27.2 will be more flexible than a 31.6

Yeah that^
If the wall thickness stays the same, a larger diameter tube will be stiffer.
I don't expect the wall thickness to come down much between seatpost sizes so it's probable that the 27.2 is more flexy

I thought so! Cheers for confirming guys.

I need a pair of 1" road forks threads extended to fit a shorter frame and I would like to do it myself...

Ive heard its pretty physical...any advice? or is it best to go to a local framebuilder/shop?

also, all Dies I have found online are 25mm whereas the forks will be 25.4mm? is that an issue?

Maybe because you're looking at metric taps? Or maybe that's the diameter of the cut threads.
Either way, I'd just look for an inch die to be safe

And yeah it won't be easy. You'll want cutting fluid, a vice and a big die holder

You won't be able to tell the difference.

Thanks alot!

@brommers can I borrow your difficult crank tool- could you make me one?

Glad you got it sorted. I no longer have my Difficult Crank Tool - I left it with Cycliste when I retrieved my stuff from Switzerland recently. I only use it to remove crank lockrings, and in the UK I can use a bench vice instead, so I thought it would be of more use to her than me.

I love my Fichtel und Sachs one speed coasters, but a couple of times when I’ve opened one up to change the grease (I currently have a NOS one from 1951 that likely needs new lube) I’ve damaged the bearing cap/retainer/seal thing.
This video has been extremely helpful but his technique for removal of that bastard hasn’t worked very well for me. Any ideas on something more likely to produce a good result, maybe akin to a bearing puller setup?
Start watching from 5.45 for a quick demo.
Thanks!

Here’s another one: I have a full size frame that matches bmx OLD, anything preventing me from using such a hub for a SS build? I understand that some bmx hubs come as cassettes, does that mean the chainline is easily adjustable?
Thanks

matches bmx OLD

120?

If the axle is the same thickness it might be possible.
Cassette hubs in the bmx world are sprockets complete with the pawl/spring part of of the drive integrated. Different to HG splines with some adjustment in the chainline.

110mm oln.

Axle diameter will be the biggest issue with most bmx hubs being 14mm. Of course it’s possible to file flats on a 14mm axle to fit it into a 10mm dropout (some hubs came like this bitd) but could be a lot of work.

On the bearing cover thing, I’ve misshapen Shimano ones when removing them but been able to reshape them with various tools to get them fitting well again.

Haven't bought a bmx frame in a few years but mine are all 120

edit: that's a lie, I have a Redline race frame that's 110

BMX is pretty much always 110 ain't it?

Yeah the last frames I got were 110. Vaguely remember having 120 on older cassette hub, probably something silly.

Thanks for this - some manufacturers offer different axle diameters so in that case it might be a go? Chainline is generally akin to 43?

I noticed a few offer the ability to run Shimano HG cogs.

More common on race hubs like Shimano DXR

Race BMXs have all sorts of weird stuff.
