George Longstaff Audax build

Btw ed I just saw this haha, still in need of some layback? :p

Sell that damn thing to me, it's actually for my girlfriend whose seat tube is actually 76 degrees.

Mind you I would find that useful to change the layback back for descending and forward for ascending.

^Click the image, it's a link to a gumtree ad i stumbled across!

Was posted 18 days ago but hope it's still for sale :)

Attaboy.

Hold on one cotton picking minute, these look rather similar...

• Incredibly powerful CNC’d aluminum short reach caliper brake.

The VO is long reach.

Slight difference in design too, like the barrier adjuster, same factory, different spec?

I have the catalogue.

Turns out i'll be getting Rigida chrina rims on my wheels rather than lx17s, the 32H lx17s were out of stock...

I had a discussion with the wheelbuilder about the pros and cons of going for a wider rim which was my original intention based on advice from people on here (tester/ed etc), and he suggested that it's unlikely to be a noticeable difference in comfort and that the crinas are more suitable for audax/light touring and the others are probably too beefy.

Very friendly guy though, wheels will be here monday :)

The Chrina is pretty porky at nearly 600g, about as heavy as a Mavic A319.

plus wider rims = 25c felt like 28c.

I'd second wider wheels, just from my limited experience of using 28's on standard narrow road rims vs A319's

Other than the touring type options there are a few wider road options which you should be able to use 23's on if you want:

• A23
  
• h plus son archetype
  
• BHS C472w
  
  

All come in silver as well which is good imo for this type of build. Also Dyad's claimed weight is fairly good for a touring rim.

Isn't the weight ~500g?

I just wish there was more info and some evidence that wider rims are better! It's hard to argue against an experience wheel builder using a couple of comments on an internet forum haha

Bah, at the end of the day I know they'll be strong wheels though and built by experienced wheel builders. which will last thousands of miles and be reliable when i need them to be

I'm not too fussed about the weight really, but yeah less is always better if you're not sacrificing functionality.

In the future if i have any trouble or when the rims wear down I'll look again into getting wider ones, but for this build looks like I'll be going with the chrinas unfortunately.
Thanks for the list of suitable rims hugo.

It shouldn't feel different from what I normally use at least, which is relatively comfortable, but more comfy would be nice :p

ahh parker has them down for 590g

Bikeradar seem to rate them 5* when couple with ultegra hubs from spacycles

There are, Zipp are using wider rims as performance are unaffected with wider tyres with a gain in comfort, recent races are running on 25c instead of the previous 23c, before that it was 18-20mm.

Conventional wisdom used to be that narrower and firmer equal faster, which turn out to be false.

You can also run lower pressure using wide rims which make the biggest difference in sore hand from road vibration.

Yeah I was aware the catalyst for all this debate came from the pro performance level with Zipp (or was it HED...) doing some work, but I don't recall it being very definitive with some caveats?

Got a link?

There's a handful of forumeanger also notice the difference between normal and wider rims, Fox for example with his HED Ardennes rims on 23mm tyres.

This graph should able to illustrated the disadvantage of narrower rims = higher pressure needed.

I notice it as well, with my 28c, I went 15psi lower than I usually do on normal width rims, the best part is that you won't need to have a lots of clearance to have bigger tyres in order to be more comfortable and still be able to fit mudguard on.

I can also fit 25mm on the ZTR's 24.4mm width, the profile shape will be more of a U shape than a bulb shape, like this 25mm on 23mm Velocity A23 rims;

Tyres sit slightly lower allowing ample rooms on a road fork and normal reach brakes;

I wants wide rims :(

Thanks for the links+pics etc, again this time I'll be going with chrinas (well the wheels are probably built by now) but in future I'll look again at wider.

Tomorrow may be the last audax I do on the current steed if i build up the longstaff soon

I just wish there was more info and some evidence that wider rims are better!

There is plenty out there on the internet. Read some HED Ardennes reviews, Zipps 303s, etc.

I've only ridden them for 8 miles so it's far too soon to say, but big daddy wayne also has a pair and has ridden them plenty, he said:

They ride superbly - I'm running them with vittoria corsas and the wider rim gives a great ride feel but the wheels don't feel 'draggy'

That's from a PM, but I'm guessing he won't mind me posting that. I'd go wide. As scoble says the pros are all doing it and they have proper comparative data and science stuff to go on...

Cheers Fox^

Wasn't long ago when BDW called me out when I said tyres width make little difference.

There's lots of progress going on with this but don't want to inundate the thread with pics.

Have got the wheelset, it looks awesome. As I've read the rigida chrina rims are a bastard to put tyres on, which is a downside, but not too bad. Not possible without a tyre lever though.

The edelux light works fine, and I'm itching to get it all built up so I can ride it up to normal speed to see how bright the light is, not just at "hand-turning speed"

Some parts that are on the way:

-10 spd cassette
-10 spd chain

• Pair of shimano r650 brake calipers (long reach)
  -Spa cycles leather bar tape
  -Edelux light bracket for caliper brakes (currently have one for canti brakes)
  
  

apart from the bars and stem which I'm undecided what to do, everything else I can transfer from the old bike (chainset/derailleurs/tyres/seat post/saddle etc)

She's looking good, will keep posted.

Here's how it's looking :)

Bars are not properly wrapped, just a loose mock-up to see how it looked.
and the black tape on the seat post is to keep it up, I accidently snapped the binder bolt...

Need to sort:

-new binder bolt
-larger width mudguards
-wait for edelux light bracket (spa cycles sent the wrong one)
-connect cables and put on chain etc

Really nice. I need to get an audax bike for next year when i have the cash.

^^Thanks!

^sigh...

is the top tube really is 53cm? it look quite long in that photo.

How heavy does the front of the bike feel with the dynohub?
