New Wheelset

Dawesy92

Right so over the winter im lookibg to build myself a new set of wheels up, I know I want the hope pro 2 evo hubs (in purple ofcourse!)

I want peoples opinions on rims, ive been looking at the ztr flows on CRC as atm they are going for £65 a rim, are these good rims?

Also if im right in thinking are they the stronger set?

Thanks,! :-)

Oh one more thing, im open to suggestions of other rims!!

Have a look on Stans site - it gives you a breakdown of what rims are suitable for what purpose. In general Stans are up there with the best.

Light Bicycle carbon rims FTW, not silly money, but you can go wider and lighter than a Flow, or tougher for the same weight.

Im not a very light guy, helmet and camelback ready to ride im about 110kg, dont really fancy risking it with Carbon wheels, plus a lad who rides for a team smashed up hia carbon wheels and I dont fancy that!

Otherwise I would haha, thanks for the suggestion though Njee

Carbon is tougher than aluminium, so he would have smashed alloy rims as well, the fact you are heavier makes decent carbon rims an even better choice.

By this quote then, what Carbon rims would ypu suggest?

Chunkers1980

The ones already suggested!

Dawesy92

Ill have a look into them then, butbi always thought carbon rims had weight limits of around 110kg, whixh would mean im on the limit...

njee20

155kg weight limit, 420g, or 145kg weight limit, 375g.

The former will be vastly stronger than a Flow, the latter weighs a lot less and is very slightly wider.

Lose some weight too, that'll make a bigger difference than new wheels ever will.

Dawesy92

Well yeah, I get the loose weight part ya cheeky git! ;-)

Ill look into it more when im back from my holidays, trying to get the mrs to buy some bita for xmas for me!! Saves me some pennys then too!!

njee20

If you have loose weight then it should be even easier to lose it. :-)

Sorry, I should have mentioned that im after 650b rims.. mybad!!

Don't worry, I'll do all the work, don't trouble yourself!

400g, 130kg weight limit,

Haha sorry, you just seem to be good at finding things so I left you too it!

Its tempting, but dont know if I can justify the cash... ill have a think! :-)

I have got a set of these

Absolutely bombproof wheels, actually stronger than my downhill wheels and lighter. Tubeless ready. Apparently based on the Flows design but a harder alloy and with eyelets on the spoke holes.
Although the claimed weight was more than my old Superstar Mavic 719 wheels I weighed them both and they were 10g lighter. I guess Hope must be more honest about the weight.

Dawesy92

Thats always good to know then! :-)

The Rookie

Eyelets just mean a bigger hole in the rim and potentially a less strong rim......an eyelet neither makes necessarily strong or weaker, it's most about how it's designed.

rockmonkeysc

Eyelets spread the load from the spoke to a larger area meaning better strength when building with higher spoke tension. They also help prevent cracks radiating out from spoke holes.

cooldad

Just seems to look more quality to me, like adding a bit of craftsmanship.

Dawesy92

Got a little bit of time yet to do more research, but so far im still tempted more by the ZTR Flow EX, not gonna be buying full wheels as its not me paying for them, hence why im gonna get rims and hubs for xmas, then ill pay to have to spoked at my LBS after xmas, ill keep thinking and looking though, thanks for everyones help!! :-)

Not according to most decent wheel builders......

rockmonkeysc

Then why would they put them on the rim if they serve no purpose? No one adds cost to a mass produced part if it does nothing (except where I work because we get a bonus for taking it out a year later!). They eyelets will spread load and help prevent cracks starting.

Chunkers1980

If you don't use them then you need some sort of extra hardening process around the 'eyelets'.

The Rookie

Exactly, many good rims have no eyelets (ZTR's, and XTR for example) it's all down to the rim being designed to use eyelets or not, the only genuine advantage (with no downside) of eyelets is reduced friction under the nipple head, but correctly lubing the rim before building removes that as well.

Eyelets mean a bigger hole in the rim (bad), add weight (bad), reduce friction (good) and can change the cost/benefit balance of various other ways of improving the rim, that is the money you spend on the eyelet you can save by not making the rim 'better' so it doesn't need them. No rule which is better unless you want ultinmate lightweight when you pay to not have the eyelets in other ways. I have rims with and without, with includes the SunRingle EQ21 on my commuter, the without include my ZTR Alpines I'm about to build into a lightweight new set.
