Any question answered...

That is such a good idea!

It's just cleaning out the threads of threadlock and gunk. I have a decent socket set with an extension as well as a Dremel.

Cheers.

So I'll hold for now and check for a suitable bolt.

How do you guys feel about scavenging for parts? A few beater bikes have been locked up with a seat post/wheel/everything except frame missing near where I live for months not. Tempted to take a few pieces I need for a cheap project like brake levers and pedals.

I know what you mean, but not for me.

I love stealing shit.

There’s money in manure.

Can I sneak an 11-30 cassette in here?
Rival22 SS with an 11-28 on at the moment. B tension has room for maneuver.

I'm guessing no, but are all compression rings made equal?

I'm working on my road bike, and it's come back from getting the headset sorted at bike shop and I have no idea where the compression ring is. I've found a cane creek 40 one at work, will it fit at home? Bike is a principia, what looks like a rebranded chris king (to my non-expert eye) headset in there.

Is this going to work?

Yeah should do, how much clearance is there with a 25?

I dunno. I haven't looked at the bike for at least a year it feels like...

Haha yeah I know that feeling

That would be quite handy, seems the general consensus is that the A600 is still king amongst ‘light roady-ish orientated SPD pedals’

are all compression rings made equal?

From a functional point of view there are two flavours, 36° and 45°. You need to use the right one.

Yes, but they are increasingly expensive and difficult to get hold of. Also, for some reason mine squeak against shoe much more than the others

Ta. So as long as the angle is right, it should be sweet, given good general fit

^ that's what she said

as long as the angle is right, it should be sweet

Well, it will centre the bearing properly. The other dimension is height, if the new one is different from the old one you may need to add/subtract shims to get the gap between the cover and the head tube right, but as long as it's above zero that's more a cosmetic issue than a functional one.

What’s the best (cheapest, easiest) way to adapt a SSMTB to be built up with gears?

My initial thoughts were to braze on gear cable stops and derailleur hanger, but seeing as I can’t seem to find ‘braze on’ derailleur hangers suggests to me it’s not really a done thing.

Internal gear hub ie alfine?

Problem solvers bodge, one of those gear hangers that replaces the qr cap. Looks like it’ll not provide me with the full range of the cassette.

Any other suggestions welcome

New frame?

Yeah, but no one wants to buy this one

If it'll fit your dropouts I've got a set of (or at least the one with the hanger on it) DMR chain tensions that came with the first generation Trailstar way back when. Run it with a full length of gear outer as a 1x?

Photos are terrible, sorry but if it'll be any use to you drop me a pm and you can take them.

That would be amazing, but it has vertical drops, chain tensions via eccentric bb. Thank you for the offer

If you want to convert this SSMTB in to some kind of do-it-all commuter/shopper/gravel thing then an Alfine is fine, presuming the spacing is around 135mm.

Why isn't there an engineering thread?

Anyway I want to learn about mechanical engineering, which textbook should I buy? Something cheap-ish that covers undergrad-level stuff.
