.....and Huw's merc/brompton Velocity rims come to you courtesy of stevegor..........

jur

Now that interests me... what did you pay for them, considering they are made here locally?

stevegor

Ummm, let me clarify that Jur,
I did an extensive and exhaustive search for them and found them on US eBay then emailed Huw with the info, who BTW still hasn't paid me for services rendered...

I have searched Velocity's Aust site and you can get your LBS to order them, sometimes there is a bit of a wait if they have to machine and powder coat them, but they are available here, not sure of the price.

BTW Jur, we were at the Lilydale lakes on Monday...thought we might have seen Connie testing out the Reach there...Nope??

jur

I ordered my 406 Velocity Aeroheats from the LBS, but even though they are made here, they are scandalously expensive... the LBS tried to charge me $110 EACH!!! I argued them down to $70 ea, which is still too much. How come overseas you pay much less for those, as has been posted here a few times (and jealously noted by me)?

PS Monday we were riding the Mississippi Creek trail, not present at Lilydale lake...

Splendid bike.

You can shed some more weight if you put on <100g carbon saddle instead of swallow (I like the classy look though :])
Did you scale your wheelset?
One of my mate built a 349 wheelset for his Tikit using velocity rims, titanium spokes and AM classic hubs. It only weighs 350g front / 515g rear.

@ stevegor: yes - once again props for the link on the aeroheats! it's mondo hard to get anything other than Deep-vs here.

@jur- I got them from new for ebay USA at $48 USD each (+p&p)

I wish you could get the aeroheats in the same colours as Deep V-s - that would rock.
Maybe if you had the gift of the gab (I don't) you could sweet talk them into a special order.

@raxel
Saddle is a Ti B17 with the sides butchered off - not a swallow (Cheaper and was already broken-in)
I did weigh the parts for the wheels yes:

Front:
Rim: 265g
Pantour Susp Hub: 250g
Stelvio tyre: 150g
Tube: 75g
Total: 740g (+ 16 spokes which I didn't weigh)

Rear
Rim: 265g
Phil Wood Keirin Track Hub: 372g
Stelvio tyre: 150g
Tube: 75g
Total: 862g (+16 spokes which I didn't weigh)

So a bit heavier but the Phil hub will last forever and it's good to have a bit of give at the front.

I was thinking of doing something similar! I have a Brooks B17 narrow on one of my full size roadies and am always interested in losing weight. Can you post some closeup pics so we can see where you cut? Any other tips on the experience would be helpful too.

Gorgeous, gorgeous bike, by the way!!!

Better than that I can post a link to a 'how-to' guide. I've done it to two now (one was stolen) and it's really easy...Best done with a Dremel or similar - mmm the smell of burning leather [cough]

How to modify your Brooks saddle

stevegor

Huw,

www.velocitywheels.com

Go to "rims" and check the colours, I think they will do special orders if you've got the moola.
Or you could go to your LPC...local powder coater, if you wanted the machined wall uncoated I'm sure a man of your infinite talents could tape them up.

pm124

LP, did you just skip holes on a 32H rim, or did you custom drill it?

Hi Steve, what do you mean by "tape them up?"

We wore through a rim on this last trip (multiple wet, muddy and loooong descents), so we need a new rim.

Jur, I paid something like $40 for mine, but they now run about $50. I like the quality of the Alex rims over the Velocity rims. The latter are drilled 24H, so it's very hard to fit a rear hub to them.

jur

Huw, you can also take a set of rims and have them re-anodised - piece of cake. Probably cheaper than painting.

Nice bike - I did not know about the modified rear triangle option.

I had clearance problems on my Birdy with Stelvios and a long-cage SRAM mech - I imagine tight cornering would scrape the Deore derailleur in the Brompton set-up too (unless it was ridden conservatively). I'd go for a 105 in black...

Sammyboy

I paid about £20 for my 406 Aeroheats, but that was on sale, and they're 48 hole.

LittlePixel

Just skipped the holes. Still looking for a good fix for sealing the holes

I think he means masking tape...

That's right, when I get frames done I have the threaded steerer, rear hanger etc taped so I don't have to get the powdercoat out of the threads. A rim would be easy to do.

Newby question: Where's SK please?

Maybe you could use this as a starting point, its cheap enough :-

Looks like Anita is selling off parts.

Hi Raxel and Brompton's friends!
I'm completely new in the Brompton's world.
I bought an old one a few days ago. I saw the serial number and some people said it gives the age of the bike.
Mine should be made in 1978 if this is correct. My main purpose is to lightweight the bike. Actually it's a 3 speeds.
I would be very happy to change this, and modify the rear triangle in order to put traditional gears instead of asturmey archer or something like that.
I read that you said we can widen the frame by force. Would you have any link I could learn from? And do you have any idea what would be the best set up for a lightweight bike? 5 speed? Someone said the rear derailleur seemed very low, a bit too close from the ground? Is there any issues with that? Is it possible to find a small derailleur instead? If you have any information to do this modification I would be very happy.
thank you very much

I remember this thread when it first came around! Hard to believe I've been here so long. I'm also curious as to how far the rear frame can be safely widened, as I'm considering installing an Alfine.

hi,

there is many issues in coverting brompton to external derrailer.
1) not possible to wider the original frame due to ground and frame clearences, you will need buy or make one.
2) rear derrailer will be an serius issue as if its too big to hold chainslack after folding it will hit ground and if its too short it will not have sufficient chain slack capacity.
3) its the most ridiculous expensive way to do this on brompton. You are not gona save money as you first thought.

au contraire, the way to upgrade brompton gearing is internal/planetary gearing.
here there is a very nice german website whose teach how to cram a nexus 8 on a regular frame brompton.
remember pick the roller brake version, than wipe roller off to makr things easyer.

Thank you BromptonINrio,
I'm going to check this upgrade from the German guy. It's always good to take a look.
But my main goal was to lightweight my old bike and I saw that the nexus is about 1,55kg. That's wonderful in terms of use but not for the weight!
Is there anything lighter for about 3 to 8 speeds than a internal gear hub?
Something else: I look at my rear triangle and I saw there's something missing under. The little welded part in order to be able to use the chain pusher thing. My bike is too old. Do you know if I could weld this little screw part myself? I just don't know exactly where precisely it is located on the tube.
I was wondering if a traditional two speeds wheel without internal gear, plus a front derailleur (it would be 4 speeds, no?) would be lighter than its equivalent with internal hub?
....

3 speed derailleur mods have been around on the net for a long time but I think quite recently someone posted an example of a 4 speed mod. One could get quite a good gear range with that, although I don't like using sprockets that are smaller than 14t with the brompton chain tensioner; the inefficiency is noticeable to me. On a bike without a tensioner running a small sprocket is ok, since there can be some slack in the chain and as a result it disengages smoothly from the sprocket. Though maybe tooth profiles other than the sturmey archer type that I've always used might rectify this.
