Ok, some idle digging on weights reveals that my Alex xd lite rims on Shimano deore hubs weigh 1000g at front and 1180 at the rear. My wire bead Conti Contact 32mm tyres are listed as 810g! Add a generic heavy touring tube and that seems a heavy wheelset. Im not sure what make or mass the discs are, but im guessing that they wont be the lightest.
So will a pr of Michelin pro 4 endurance in 25 or 28mm be a waste of time until I buy a lighter wheelset?
thanks
Pro4 Endurance are a nice tyre. Don't have the pace of a full on racing tyre, but still fast rolling considering the protection they offer.
You'll likely have both faster tyres and save 500g off each tyre so would think you will notice the difference even before a wheel upgrade.
Breninbeener, I can't answer your question, but if it's any help I've measured a 28mm Pro 4 Endurance on my kitchen scales together with a few other tyres for comparison, including the 32mm Hyper:
23mm Pro Race (version 1 or 2, not sure which) - 214g
25mm Pro 3 Race - 221g
28mm Pro 4 Endurance - 291g
28mm Vredestein Senso Xtreme Weather - 273g (measures just over 28mm fitted on a Kinesis Crosslight wheel)
32mm Vittoria Voyager Hyper - 410g
40mm Vittoria Voyager Hyper - 466g
Incidentally, with regard to wider tyres, what about the rim width? Some manufacturers, like Pacenti, are promoting wider road rims which will alter the shape/volume of the tyre. So, is a 23mm tyre on a 20mm rim going to perform better than a 25mm or 28mm on a 15mm rim?
Ok. I think my current rims are 18mm internal. I have just ordered a pr of Michelin pro4 endurance in 25mm flavour!
Thank you for your input everyone. I will report back 🙂
Hooray! I've got some rather aged Duro/HwaFong 28c on 24mm Mavic Module 4s. 36 beefy spokes. I might nick the Ultegra wheelset off the wife's bike for some compare and contrast.
@nedrapier......let us know how you get on. What tyres are on the ultegra?
28 gatorskins. Some love 'em, some think they're all dead and slow and slippy. I'll get some decent tyres at some point and give them a try on the ultegras for a long ride. Won't be for a while though, weekends are taken up for a month or 2, rides are short, dark and muddy!
Mason Definition is very nice but the Mason Resolution is better - but that's because I have one off-course. Hunt wheels (carbon 38's) and 28 Vittoaria Corsa G+. Very happy with that combo so far. 2 months and almost 1750km.
Bump.
Any thoughts on the Genesis Datum?
Looks about what i'm after (perhaps a fraction overweight), supposedly has fittings for guards, but I can't find any pictures showing eyelets on the fork.
Seems i've trashed the chain, cassette, big ring and rear mech on the Boardman CX, so may well be heading to the skip after winter 2017/18.
If you're really after an audax bike, there are some good deals on the genesis equilibrium decade on ebay - guards, rack and dynamo front hub, plus a triple, for about £800.

Spectacularly fails the good looking test.
When you come out of the cafe freshly caffeinated to the max, seeing the bike propped up and waiting to go is supposed to bring a smile to your face not a grimace.
Edit: Having had some time to think about it more, and having knocked out another couple of 200km rides, i'm even more sure what I want is a light, fast, efficient bike with bigger clearance and mudguard mounts to increase practicality.
Yes it has to be comfortable (I don't really find a full on carbon race bike uncomfortable), but if i'm going to ride a bike lots of miles it has to also be fun to ride.
I have two "audaxish" bikes - a Thorn Audax (original version) and a Mason Definition. They're quite different in character: the Thorn is very compliant and slow-handling, whereas the Mason is more sprightly. Oddly, I find them about as comfortable as each other on long rides, and would say both are really well suited to the task. The Mason is far nicer to ride when you want to push on though, and looks fantastic. I had to have one road bike for everything, it would be top of the list.
I did my first audax a few weeks ago on the Randonneur - 200km plus another 25 to and from the start. Bike went well, my knees, less so!
I'd love something lighter, but with the Raleigh, I can just about get away with 5.10s and flats, not sure if I could do that to a Mason Definition!
Plus I Don't Need Another Bike. This is a perfect single road bike for me. commutes, shopping, long rides, errands, pub rides, some light bridleway bashing.
If I did, though, I think that Mason would be top of my list, too.
Well, i had a 45min test ride on a 2016 Pinnacle Dolomite 5 today. Ironed out poor surfaces well, didn't feel too heavy when climbing or accelerating, and generally rolled along at a nice pace.
Didn't get on well with the position and handling though. Felt the head tube was too long putting me upright like a sail, and reach was too short. Handling i felt was very stable, but very slow and as a result just not a fun engaging ride.
So a bike capable of going fast that wants to go slow.
Just added this to be my main distance bike, although it sounds like we might differ a bit of what we want from a distance bike. I was looking for something similar to my old Roubaix but a bit more modern and with hydro disks and Di2 - and it helped that it was £1700 cheaper than the equivalent Roubaix as well.

No mudguard mounts and suspect 28mm tyres are probably as wide as it'll go though.
