Having recently destroyed a Pacenti TL28 and had it replaced with an Arch Ex I've now flat spotted it to chuff on it's maiden ride in the same fashion. Fair enough it was riding in Torridon on some rocky trails but I know that I could have dropped the QE2 or possibly even the QM2 on my old xm819s and they would have come up trumps.
I'm a fairly light/average rider at 72kg and ride a reasonably absorbent trek remedy so don't understand why outwardly "trail" or "all-mountain" rims seem to be so pants at mountain biking. I don't want to have to go back to my old xm819s as they're narrow and heavy but they keep looking at me in a 'told you so' fashion and I can't help but think they're right.
Any opinions on tough but light rims that aren't carbon (i.e. <£80 a pop.)
ignore me, i'm an idiot.
if you consider 819's to be 'heavy' and 'narrow' - i can only guess that you're after something 'lighter' and 'wider'. yet just as resistant to flat spots.
want some shooting stars to go with that moon-on-a-stick?
i refer you to my first comment.
(my less than sexy 719's have proven to be bombproof, and hold onto a 2.4 Advantage no problem, but i AM a mincer)
Tyre make and model and air pressure usually have something to do with it! Rims only flat spot when the rim contacts the deck. More air is usual all that is required - standard tyres (none UST) usually have thinner sidewalks so need more pressure!
That or you have been putting on weight!
Humm, you could try flow rims and higher pressure. Being a light rider is about more than body weight and suspension travel.
[i]Rims only flat spot when the rim contacts the deck[/i]
this. up your tyre pressure.
As above 819's are a pretty good compromise of light/strong.
never had a problem with my 819s........
I have smashed Crest's on my HT (lighter than the Arch) through just about everything you could imagine, I'm 15kg heavier than you and only mince when I'm hungover. Never flat spotted at all.
I'd say either your wheelbuilding or builder is shonky or to low a pressure ( I run 24psi tubelss no probs at all)
Hmm, I run about 30-35 tubeless and that pinch flatted when the ding happened so maybe I was just unlucky. The shop that built the wheel have a pretty decent rep as far as I'm aware so can't see it being their fault. hmm.
I have to say although a slightly different prospect my D521s have lasted 10years ps Im not a light or neat rider and generally consider my self a part wrecker !
Oh theres 6 years a peak bashing in there too
I have both arch exs and flows for my trek remedy and have never had a problem.i ride fairly hard and weigh a fair bit more than you the flows are definatly more sturdy I also run tubeless with very low pressure 20 psi at most
Now I'm a big lad and (think) I ride pretty fast, when gravity assists that is.
Ive not yet?managed to destroy or even come close to destroying my Mavic 729 rims
These are my Alp rims and have survived three trips having flattened a DT Swiss 5.1 rim on my first visit to an Alp.
My Spank Ozzy rims have also had a hard time on my hardtail that gets used all the time ion the UK. Not even bent them yet. Im impressed by the Spank rims more as theyre dead light too.
721s always work for me and i dont think my wheels are that heavy..
As a heavier rider with a limited budget, my personal choice of rims has always been: D521 for XC/freeride, D321 for big hit bike, and a decent 24" for street. Make sure they're welded, eyeletted, and don't run the tyres so low you are dinging your rims on rocks!
I've had lighter XC rims the eyelets have pulled through on, pinned and sleeved rims that simple separate, and wide, trendy rims that don't like staying true and do a good impression of cheese.
719s have been good to me. smashed down the alps, 2nd time on a hardtail. pushed the mech through the spokes and rode 2500 m descent on the last day. bit wobbly by the time i got home straightened up and still going strong.
A good build is more important than rims. you using a good builder?
I'm just in the process of having my DT Swiss XR400's replaced with ZTR Flows as the DT's have flat spotted quite badly front and back. OTOH On my FS 5 I run Mavic 317 front and 521 rear and they have survived some serious abuse still run true and no dents.
721s here, I'm a fat biffer. They don't seem too heavy
