is there any weight saving? aerodynamics with less wire all over the place?

not sure about weight savings. don't have the actual specs yet though, but i reakon it would probably weigh more because it has to have the battery and the motor, etc. still run cables. don't have the catalogue with it in yet so have only be going off very small pics on their online ordering site. they don't even have them listed on their main website yet.

also if the battery, charger and cables aren't included in the price above (not sure if they will be because i just got the individual prices for the shifters and 2 derailleurs and added it all up) then you can add another $650 onto the price. taking it to around $4000 for the setup. and that doesn't include cassestte or cranks. so what you pay for just the electronic setup, you could nearly buy a complete bike running the manually operated version. and at least then if something goes wrong you know that any bike shop will be able to fix it, as this requires a diagnostic tool which wholesales at over $400 (depending on the problem). something i'm sure as hell not going to invest in.

and yeah campag is good.... if you can afford it. 11 speed ftw

ok, just spoke to mate from a shop in brissy who went to the shimano trade show last night. they had the di2 stuff there. looking at about $3600 to $3800 for the full electronics kit (shifters, battery, cables and derailleurs). he said it is ok, but it seems to be more something they have done as a prototype, like how car company make all those cars for the international car shows each year and half of them never actually go into production, and the ones that do often flop after 6 months. he said the some of the stuff was pretty rough (such as the diagnostics unit) and looked like it had been made out of a lunchbox and some lights.

something interesting that he pointed out was that if it is fitted to a carbon frame (and some lightweight alloy frames) and a special backing plate is left off when mounting the front derailleur, you will end up with a hole in your frame the first time you change gears. this is because of the fork in which the motor has to push on the frame to move the derailleur. he also said it has some trimming functions which it automatically does. this is when, for example, you are in the smallest cog on the cranks and the largest on the hub (easiest gear) and if you then change down to the smallest cog on the rear, the derailleur will move over slightly to stop the chain rubbing on it. most of the road bike shifters already have this function though, it just isn't automatic. you just move the shifter about half or what you normally would to change gears.

found this video on youtube about it

lol seems fairly pointless.

ahaha, not quite jase, cause he would have to post the wheels up here first.

no i'm not in vic, i'm in qld

lacing isn't that hard to do once you know what you are doing. if you don't know what you are doing, even just trying to copy a wheel you have sitting next to you can end in disaster. if someone brings a wheel in to me that they have tried to lace and stuffed up, i charge extra to fix it because i have to start from scratch (charge a fee for removing the spokes). often what they do it tighten each spoke up all the way before they put in the next spoke and this ends in disaster (and can end up stuffing the rim)

the problems from incorrect lacing range from sideways buckles (easy to fix), incorrect offset/dish (also easy to fix... most of the time), up and down buckles (harder to fix), rims being damaged (can't be fixed)

if all you are doing is changing the spokes but using the same rim and hub (or changing rims and using old spokes and hub), this is generally pretty easy as you don't have to calculate the spoke length. you can just measure the length of the old spokes.

dishing is also easy, again if you know what you are doing. generally using 2mm shorter spokes on the drive side will give you enough difference to dish it easily.

I should be getting my stuff online from now on, and i can actually post you the rims/hubs and when you're done, you can mail it to me, but its just a thought.

cost of postage will probably cost you about $60 all up. maybe more (just guessing). then you have to hope they don't get buckled in transit.

as for buying online, make sure you shop around first and compare the prices to your local shop and take into account the cost of postage. if it is an american online store it will more than likely be lots cheaper, but if it is an aussie store, by the time you take into postage often it will work out to be pretty close to any normal shop. with bmx stuff i run it at the same price as the main aussie online stores, so when the kids come in with something they bought from them i usually make fun of them telling them they would've got it cheaper through me. as for buying stuff from out of the country, if it is something that comes with warranty, to claim the warranty you have to go through where you bought it. you can't just take it into a shop near you and try to claim it (since most companies require proof of purchase for a claim).

and something i meant to add about the electic shifters, i think it will end up being like the air powered shifters shimano brought out a few years back. expensive as hell and no-one bought them

that's them

the guy from the other shop in town hasn't even heard of them, LOL

[Xmetal]

I remember seeing them ages ago in AMB mag, they had a 'subscribe and win' comp with them as the major prize. weren't they made primarily for DH/FR?

Yeah, that was just a thought.

CRC does free shipping for purchases over GBP$400. They're pretty cool, i've ordered from them. And their stuff are pretty competitively priced. Like how the RS Reba costs $899 here but on CRC, its sub $600 after conversion to AUD. If i tack on some other random stuff, which i don't really need, i probably can get the free shipping.

Back in singapore we used to do mass orders since singapore was so small, one end to the other takes an hour or less.

And i reckon its hard to beat aspirevelotech's prices for chris king stuff.

yeah they were dh/fr gear. only problem was in a crash the air lines were getting ripped off and the tanks were getting damaged, etc.

i have built up 3 wheels this morning. 1 bmx and 2 hybrid wheels. when i was taking the old spokes out of the rear hybrid wheel (i was cutting them cause i had to put new spokes in) and the old spokes had a common problem where they are supposed to be stainless but rust and start breaking, even if there is no pressure on the wheel (can let go with the bike just sitting there). anywho back to my story, i had cut about 2 spokes and was about to cut the 3rd spoke and a different spoke let go and shot up and hit the roof (about 4m high roof) hard enough to make a dent. i've had them let go while the wheel was on it's side and they have flown about 15m across the shop

[Mr Eps]

hey marc

do you stock velocity wheels? i may buy a pair off you =)

i want some brake-machined deep V's

let me know a price =)

[mad082]

what sort of hubs? sealed bearing or looseball?

[Mr Eps]

=/ what's the difference?

it's for singlespeed non fixed soooooooo i dunno whatever is the ... option i want i guess.. haha

[Xmetal]

Sealed = less/no servicing

[mad082]

correct, but a well adjusted loose ball will roll faster

[xALmoN]

loose ball hubs are like, shimano hubs?

[mad082]

yeah. sealed bearing run bearings that look like bigger skateboard bearings

although if a bike says on its specs that it has "mechanically sealed" then they are looseball, they just have dust seals..... like every other loose ball hub, LOL

[xALmoN]

Sealed bearings and cartridge bearings.. whats the diff?

And the bearings in the king headset, are sealed yeah?

[Mr Eps]

jesus... loose ball then... haha sorry for sounds impatient but i cant get on sau during work hours which is the only time i can contact you... stupid new job... and their stupid.. ive had it up to HERE with their.... REWWWELLLS.

all i wanna know is how much you bai for purple anodised machined-for-brake velocity deep V wheels

=)

[mad082]

Sealed bearings and cartridge bearings.. whats the diff?

And the bearings in the king headset, are sealed yeah?

sealed and cartridge will generally be the same, however in some circumstances it can mean a slightly different setup (bearings themselves will be the same, just how they are held in is different).

rowan, i'll get you a price today
