Weight Problems

[powinc]

At 95kg can I just choose any aluminium road bike frame with certainty
or should I be selective? And does the same apply for wheels, are some
more weight bearing than others?

Thanks for that Byron.

I didn't realise that Al. bikes broke that often, I knew most Al frames
had extensive warrenties against breakage. I have planned to lose some
weight anyway.

You shouldn't have much of a problem at that weight as long as you buy a
half decent make. I weigh just under 90kg (was 95-ish) and have owned a
Raceline Alum MTB, and now own two Cannondales (based on CAAD5 road and
CAAD5 mountain frames) and they have all held up just fine. Obviously
the Raceline was a lot flexier than the 'dales .. I haven't had any
problems with comfort either.

As for wheels, you'll have no problem with a quality set of handbuilt 32
spoke rims with CXP33 or Open Pro rims. Machine-built wheels can be a
bit iffy though, they seem to go out of true a lot easier. I've even
heard of people our weight using Ksyriums without any hassles ...

Yeah, i guess you do have the warranty, and that is good for piece of
mind, but for me i just got sick of having a bike for a few months and
then waiting 1-3 months to get a new frame each time. It is really an
inconvenience.

Thanks for that info, Rek

I've been looking for a 2nd hand road bike and a Cannondale would be
nice, I might pickup a Caad 3 or 4 for about $1.5K, it's just a matter
of finding one.

As for the wieght issue, it was brought to my attention by the guy who
makes the Evolution frames in Geelong www.evolution.net.au. He had a 2nd
hand frame there, but he said I may be a little heavy for it??

As for the wheels, should I steer away from the Shimano 540 type which
seem to have less spokes? And I 'll keep an eye out for CXP33 or
Ksyriums rim when choosing the next bike.

So as you said I will stick to the decent brands and take it easy on the
bike untill I down down to about 85kg.

Thanx again for your help powinc

How big were these frames? I weight 97kg and I've never
broken a frame.. well, not counting the ones that have been
run into something hard!
Are you talking about mtb or road frames? Both my alu
mtb and my alu road bike are fine after a few years of
"heavy" use.

What were you doing - hucking your 'dale off your shed
roof or something?!

Damn, you are one unlucky dude!
Are you buying super cheap parts or what?

Nice in theory.. unfortunately it doesn't always help. Skinny b*tards! ;-)

As a heavy big bloke (6'4", 100kg), the frames I have had have not been a
problem (steel road frames however - now on a Al MTB frame) - the biggest
issue has been the wheels.

As I can never afford a top of the line bike, I end up with pretty crappy
stock wheels - and these usually need replacing within about a year (rims
and spokes at least). I had replaced everything enough on my road bike I had
so that it ran beautifully on the wheels - and they no longer needed to be
retrued every 2 months.

I had a Shimano Deore LX front hub, Campaglio front rim, Atlanta 1996 rear
rim and an unknown rear hub.

Your mileage may vary however - I was doing all weather commuting and
knocking it round a bit.

Cheers,

Tim

As much as I like Cannondale frames, I have to add the disclaimer that they seem to be a love or hate proposition with a lot of people.. it'd be worthwhile giving one a go and seeing how you like them.

Well, the guy does wrote:

A common OEM wheel on low- to mid-range road bikes are the Mavic CXP21
or 22, which aren't half bad. You won't find Ksyriums at that price
point (they're Mavic's high-$ prebuilt racing wheelset) unless you just
want the wheels and no bike to go with them.

I haven't really heard much at all good about the Shimano 535/540
wheelsets ..
