Looking For New Wheel Set

[Nibor]

Is that for a pair?

Yes it is and they arrived in less than a week

 

[Nibor]

They are a sturdy wheel holding up to pot holed Lancashire I am very please with them

 

[Nibor]

Good to know about the Mavic Open Pro's and they are holding up for you. Was you having the same issues as me with cheaper rims not lasting.

Not to be offensive but it is a pet hate of mine you appear to be referring to wheels a rims. Rims are the part around the outside of the wheel which the spokes attach to using nipples the whole thing is a wheel. Pedantry over LOL.

No I am a firm believer in tools for the job and a 135Kg guys really needs 36 spokes for a durable wheel and I was going through the same process as you and thinking god this will be expensive and spotted these and thought they were exactly what I was looking for at a very reasonable price. Don't forget to order rim tapes!

What tyres have you been using? At 115kg it may be that the tyre + wheel combination isn't right, too narrow tyres, too high pressures could lead to a lot of short sharp impacts, while some 28mm tyres could stop that happening. If they fit in the Defy, that is. I'm around 90kg and have commuted for 4 years on a pair of Fulcrum racing 5s with 10kg panniers (bike is light ~9kg) and I've never had a hint of a problem from them on 25mm tyres at 90psi.

Seems Defy 4 comes with 25mm. Definitely try 28mm if you haven't changed the tyres.

I doubt you need new rims,

a 135Kg guys really needs 36 spokes for a durable wheel

Si - you may doubt OP 'needs' new rims but the 010s have only 24 spokes.
@TheJDog - your Fulcrum Racing 5s have 18 on the front and 20 on the back - so they're doing well to support your 90+10+9; lucky you.
Robin shows the way and '23mm' also suggests that: for the heavy lad, 36 spokes offers a wheel that, provided it's well built, will be strong enough and much less likely to fail (as the OP's Giant and now these wheels seem to be prone to do). Does the OP particularly want a light wheel?
Agree with @TheJDog that, for a higher load (or even for 80kg) choosing 28s (provided the Defy frame has space) is also very sensible. All the wheels mentioned will run with 23mm - 28mm entirely 'happily'. Weight difference between the different widths of tyre is minimal and rolling resistance of a wider tyre is less, at the same pressure. If space is tight, for information the Conti tyres often come up narrower than described.

Hi all,

Current tyres are the standard Giant S-R4, Flat Guard, front and rear specific, 700x25mm which I have been running 120PSI on the back and 115PSI on the front to try and stop tyre pinch.

Not sure if the Defy 4 will allow for a 28mm. How can I find out

I would recommend a wheel true and replacement spokes ( for more robust versions) will probably cost £100. My lbs did this which allowed greater tightening...or something...and my old wheels behaved impeccably since (I had lots of issues prior to this, from creaks ro cracked rims)

I could recommend a set of wheels that would suit you perfectly but I'm afraid they are not in the right price region.

700x25mm which I have been running 120PSI on the back and 115PSI on the front to try and stop tyre pinch. Not sure if the Defy 4 will allow for a 28mm. How can I find out

Look at the space between the current tyre at the points it comes closest to the frame (ie fork, seat stays, chainstays). Is there a spare 2mm or not? 28mm tyres are ~1.5mm wider (each side). Don't think the diameter increase will be an issue unless you're running mudguards.
As far as pressure is concerned the load on the wheels is 115kg + 11kg weight. Split 53/73 front/rear (say). This authoritative article (attached) is useful to determine correct tyre pressures (the front seems a bit high for 25s). The graph gives 102psi in front and a whopping 143psi on the rear. A typical 25mm tyre has a limit of 120psi, so you are already risking pinch flats on the rear. A 28, at least on the rear, for the heavier bloke, is definitely recommended.

 

[chrisb1357]

So basically I need to first check that the Defy 4 will take 28mm tyres with out mudguards.

Then decided on new wheels and tyres that will support my weight

Run them on the optimum pressures

Chris

 

[Ajax Bay]

That three point plan seems good. Pressure in the rear may need to be restricted to the manufacturer specified maximum, depending how much notice you take of those. My 28s (Conti GP4S) have a max spec of 115psi and for you the graph will 'demand' more than that, even on a 28 (actual). Bear in mind also, that you will need to get your wheels on and off, so the brake calipers will need to open far enough to allow the inflated tyre through.

I am just torn if to go for them wheels from ROSE or hand built. Big difference in price

I assume the Rose ones are handbuilt, just by someone overseas? Spacycles have a good rep for wheels too. What are you comparing the price too? Which wheel Builder?

[chrisb1357]

23mm is the wheel builder who has quoted £230 for a wheel set. Ok its not the same spec as the ROSE ones but the ROSE ones are £150

£80 difference

Ask the wheel builder to use cheaper parts?

The Defy takes 28mm easily without guards.
