Custom lots-of-titanium Brompton

Try to buy it from http://goods.ruten.com.tw/item/show?21304052937815.
Can anyone tell me what is the reach of brompton front and back brake?
I want to get the brake and is considering brakes from Mr Control, x-eyed & oval concepts. I need a long reach arm brake that has lines on the left of brake mount so that I can fold the bike.

I got my carbon fibre mudguard from ONESEVEN

Thanks Kllow14, looks like it's time to start buying things from ruten.com.tw. I'm getting my mudguards from ONESEVEN as well - a few communications issues at the moment, but I'm sure we'll get there.

I've measured my Brompton brake calipers. From the centre of the mounting bolt to the centre of the pads, the front is 51mm to 67m, the rear is 50mm to 65mm. Roughly.

My mudguard is here. Price is good but the finishing is not so. I should sent mine for further lacquering.

FYI, I have measured original chain tensioner and Bikefun tentioner (shells only).
Original : 68g (including a few nuts as bikefun does not need them)
Bikefun : 150g
So there is over 80g difference, but still bikefun looks nice though.

There is rumor that Brompfication is planning to release chain tensioner (but can not be lighter than original).

how much are the mudguards?

1420HKD for the mudguard, flap and wheel block, all in carbon, together with shipping. That's about 117GBP.

The mudguards have arrived, despite Parcelfarce's online tracking claiming they're held at the depot due to an inadequate address. Here they are:

The steel bolts on the rear 'guard could do with being replaced with ali ones as they more than double its weight, and I'm going to replace the silver pop-rivets with black ones. I'm also thinking of giving them a quick coat of laquer, as the finish is the normal finish you get with vacuum-bagged carbon so it's a bit uneven.

I'm pretty pleased with them though.

Sure that might be wise? Make sense to replace them on a normal bike, but giving that it's a Brompton where the weight of the folded setup will be mostly on the mudguard, the steel mount would be more robust.

IMHO etcetera.

I won't replace the ones holding the stays onto the frame - they're heavily loaded in sheer when the bike's folded. However, the ones holding the stays onto the mudguard are only lightly loaded, since the weight of the bike itself is taken by the stay, and the bolts merely stop the stay (which curves round inside the mudguard) from slipping out of place. And if they break, I'll switch them for steel. And curse a bit.

This is a brilliant project. Really impressed with the 'dining room' and obviously the Brompton.

This bike is still the best project after the shed (obviously)

Danstuff,

Will you be changing the brakes or using the originals?
There is not much of an option for brakes.

@danstuff Chapeau! Lovely looking build.

Just got a Brompton myself and tweaked a few things.

Thanks people. I'm currently in the process of sanding and polishing the carbon mudguards, having given them several coats of clear Plastikote. I'm planning on using the standard calipers, Kllow14, but with Swissstop Green pads. A brake caliper's basically just a lever in my book, and unless it's made of cheese changing the caliper's not going to make much difference to the braking. Changing pads, on the other hand, can make a real difference.

Time will tell if this utterly convincing theory is entirely correct or complete bollocks.

To further lighten the bike, you can consider getting titanium bolts from Toronto cycles. Very good deal.

Isn't this build totally about your aesthetic? And making things work a bit better?

ie. the calipers (apple + delete, apple + shift +delete)

What does the apple thing mean?

I sort of agree with you on the calipers, especially with wheels this small. I've got shit single pivots on my Dawes KinPin on steel wheels, but they work well just because of the wheel size and general speed.

Although Shinscar I do see your point (without the apples) and would have expected at least a ti upgrade on the calipers ;)

Fark! 120 gns on mudguards! And you want to replace the hardware cos it's too heavy #firstworldproblems

Sounds like this brompton's going to be full-on viral bike pron when you get pitures up.

If I knew how to subscribe to a thread I would do this.

What does the apple thing mean?

On an Apple keyboard, they used to have the apple symbol on the command keys instead of a command symbol, fortunately they have removed it not long ago.

Probably a marketing tactic to make people think "apple" all the fucking time.

You already did when you comment on it, but to subscribe without commenting, look at the second grey header below the first one, and find thread tools - drop down to subscribed to this thread like a mother.

Velocio, y so serious?

You don't like the "You know nothing edscoble" meme?

I'd say that's a pretty fair summary, yes! However, the trouble with the calipers is that they're rather unusual in that the cable enters from the bottom. It's possible to re-route the cables so they enter from the top, but that rather screws up the fold and so doesn't make it work better. It's possible to bodge an adjuster and clamp onto standard calipers to reverse the cable direction, but as you can probably tell from the word 'bodge' I don't find that option particularly aesthetically pleasing.

If I find some billet titanium upside-down cable calipers, I think there's a fair chance they'll make it onto the bike. But at the moment I haven't.

For same reason, I did not replace break calipers. Although I kept original caliper, I replaced original bolts with Ti bolts.
