Thanks! I tried a half link - unfortunately it pulls the wheel a little bit forward and then the tyre contacts the mudguard bolt and locks up...so it seems my magic gear calculation was a bit off as I did not account for tyre clearance issues.

I have a alfine single pulley under chain tensioner in storage, I'll probably add that just to have some peace of mind. The chain isn't coming off at the moment, but once it stretches a little bit I am sure it will be wanting to jump off with every small bump.

Finished my Paris cobbles commuter. Wheeler mtb frame from the 90s...unfortunately not retro parts after that. 7 speed IGH, dynamo front wheel, swept salsa bend bars, internally routed electrical cabling.

I think I will keep it geared, but rarely use the gears. I think converting it to singlespeed will take away from the vibe of the bike.

Looks like your picture link is broken. Do you mean this?

I may have to take it to the shop. Alternately I could take this website's comment that most lower end french bikes will be 26.2mm . And then if the seat tube is slightly larger (26.4mm) I'll just shim it up with a can from a local Parisian beer for authenticity.

That's the idea! Still debating flat vs. swept bars. Need to find some inexpensive one. But maybe a slight sleep would be nice.

Cactus dynamo = dynamo is broken. It is indeed a bottle. I'm tempted to pull it apart to see if it can be serviced without buying anything.

So a bit more annoyance to the seat tube. The seatpost is actually 25mm. Looks like someone sized it down as there's some welding flux at the top tube which wasn't cleaned up. I decided to dremel it down, and only realised afterwards that all the metal shavings were going down to the BB! Doh! Flipped the bike upside down to get the bulk out.

The seatpost now goes into the seat tube and has some play.

How do I measure the inside of the seat tube past the messy opening near the top tube? My caliper won't reach 30mm down inside....

More pictures:

• Crank is cottered. Means low quality bike to begin with. Brand is "Erval"? I think. Need to clean the rust off.
  

• RD 5 speed Huret
  

• "Ravo" stem....with some wood insertion in the back? Looks dodgy.
  Edit: actually "Pivo" stem
  
  

• Chrome plastic lug cover...screams cheap frame...
  

I think from the markings, and the lugs that this may be a French "Special C.N.C" regular steel tube frame of some sort. Bottom stamped serial is E2610. Unfortunately with french bikes all the tube sizes are weird. I started by measuring the exposed seatpost. To my horror it's ovalised at 26mm x 24mm. It needs to be removed anyway.

I'm estimating maybe the seat tube is 25mm. But I need to clean it up and measure properly....then gamble on the size. Apparently french bikes have no standard sizes.

This is my first ever beater build...

I currently live in Paris, and the prices on leboncoin (french gumtree) of bikes are skyrocketing up because of people desperately wanting to ride instead of catch a packed metro. I picked up this beater for 100eur, way overpriced I think, should have been 70ish but should do well for a beater build to commute to and from work/pub/boulangerie. It rolls pretty well, completely functioning actually! And it has 35mm tyres which is good for cobbles. Dynamo is cactus, brakes are scary but working.

So, the idea is my budget is 3-4 months worth of navigo (french oyster) pass, so if I can spend the summer without buying a monthly pass the bike is paid off.

The build plan is:

• replace the god awful seat
  
• flat bars and levers
  
• front basket/rack
  
• general overhaul on brakes
  
• not touching any bearings until winter

@freddo probs just a sneaky ride to Adelaide for a pie and thumb drive!

wetransfer seems to only do up to 2GB, the whole package is 5.2GB. I created a private torrent file for you, check your PMs. It'll probably take a while to transfer, because the NBN rollout in Perth is only to the suburbs in which certain State MPs reside in.

Edit - I replaced my battery in my former A1278 well before the battery swelling...new machine quite likely indeed. Let me know if you still need the 10.6, otherwise I'll take it down.

I've got a 10.6 dmg I made from the DVD, I used it often during my A1278 days (even made a small recovery partition with it!). Also have TRIM support enabler for 10.6 as well. Not sure how to get both to you, I'm located in Perth AU.

As per Aroogah's link, I used ferrules. I don't have a crimping tool, so I lay it on a bench vice and used a blunt cold chisel and a hammer to crimp them.
I can loop it up into a circle of about 15cm that can then be pushed into an oval as my pocket is rectangular. As it is wire rope it does have a bit of spring to it so it isn't as "squashable" as other alternatives.

For bikepacking I have a hardware store DIY job: ~80cm of 3mm-5mm braided steel cable that I have crimped to have small loops at the ends, and a tiny but good lockwood padlock (basically the size of a luggage lock).
Allows me to loop it all up and slide it into the map pocket of my frame bag, is light enough, strong enough to be a hassle to any would be thieves at an isolated campsite. Can loop it through frame between frame bag, and through wheels.

Did a bit more research. I think I'll use a Node with an overclocked GTX 970, that'll take one TB3 port on the MBP, and on the other I have an apple adapter with pass through power TB3, and a USBA 3.1 Gen 2 port, apparently it delivers the same speed as USB-C. Will just use a different cable for my Samsung T5 (USB-C to USB-A).

Edit: Nvidia vs AMD for eGPU and macOS? I read nvidia should work now under high sierra with a patch or two...is CUDA implementation also supported? Would like to run some statistics programs with CUDA implementation under macOS, if it's not overly friendly might have to look at an AMD card with OpenCL.

I'm in straya at the moment, so bit far for postage =S.

Ideally I'd like to store bootcamp externally to the egpu - looks like the HP Omen accelerator could fit the bill well. It has one TB3 port, but has space for an SSD as well. Only question is if the macbook will recognise the SSD at boot!

Shill me some TB3 eGPU housings.

I have a MBP 2016 13" with i5/8GB, so only two thunderbolt ports. One port will be power, the other eGPU. Are there any housings that have a second tb3 port to daisy chain an SSD into it as well?

Which eGPU housings seem to be best performing?

Edit to add - leaning towards an Akitio node at the moment

I'm in Aus - was about 8.5%.

Got my bog standard refurb nTB MBP a week ago. i5/8GB/256GB. Not too fussed with going the 256 option as it is removable on the non-touch, just a matter of time before the aftermarket works out how to replicate apples ssd controller.

Bit of a bonus - went to pick it up from the store and got chatting with one of the apple assistants about how I got it for study etc - he then mentioned that the refurbs aren't subject to edu discount (which I knew) but the applecare is! He dropped the applecare price for me. Refurb with 3 year discounted warranty. Not bad.

Not sure if repost

This is what I use. It's the cat's pyjamas.

Many cutthroat, such salsa.

Cheers - I did end up installing eOS with a lot of ubuntu-based mods, but the end result was that it didn't perform as well on the aging apple hardware as I thought it would (slower, processor overheating even with tlp and a fan daemon installed). To be fair, I didn't meet the minimum requirements specified on the website (i3 minimum vs my core2duo) so that was probably it. Back to the insecure snow leopard for me.
