Wheel recommendation for heavily loaded bike.

Barry McCullagh said:

Hi, I am currently looking for a new rear wheel for a mountain bike. Im 6'1, 220 pounds cycling
over 100km per week to and form college. However, I am also a thrower and sometimes (once or twice
a week during the summer and occasionly during the winter) need to carry 2 or 3 discus (at 2kg
each) and the occasional shot put (at 16lbs). The roads in question are pretty poor, Irish roads,
so it involves riding over big potholes, bumps etc. I also carry a change of clothes, some lunch,
waterproofs, tube, repair kit etc with me, totaling about 35-40 pounds.

I know people have asked about rear wheels for heavy riders, but Im not sure if my requirements
are the same as theirs. Shots and discs dont absorb the shock like a body, they just slam down on
the back wheel after a bump. I have been looking at some cross country/downhill rims, (Mavic 517,
519, 521, Sun Mammoth and similar). I know they are strong and will withstand the impacts, but
will they be strong enough to take the constant load. I was also looking at touring rims - never
having toured on a bike, do people normally carry that weight of gear with them?

Also, I was hoping somebody could explain the advantages of more expensive hubs - lighter,
stronger, and or anything else?

When I do decide on rim and hub, is there anyone from Dublin, Ireland who can recommend a good
lbs? Merlincycles in the UK have some good offers, can anyone comment on their wheel building
ability?

I originally posted this in rec.bicicyles.tech and people suggested the following: -> Xpost here
-> Mavic d521 with DT competition 14/15DB spokes and an XT hub -> Sun Rhino Lite/Bontranger
Mustangs with Chris King or similar Hub.

As this is a bike I use for commuting only, it has 26x1.5 semi-slick tyres on it. Will this tyre
size fit the above rims (I know the mavic site doesnt list it for the D521).

Many Thanks, Barry

Maybeyou need a trailer to carry all that.

Look at "Tandem" wheels. wheels meant for Tandem bikes. High spoke-count..... built like a
brick-sh!t-house

Not the point, it's just annoying to scroll through pages of stuff that we've already read to read a
two-line reply.

Mavic d521 with DT competition 14/15DB spokes and an XT hub

Many Thanks, Barry

I can definitely recommend the D521's with XT hub, which is what I'm currently using. My riding
weight, while considerably less than yours, was about 200 pounds. But since I also use the wheels
for dh as well as xc, I believe they are experiencing much more stress than what you'll be
inflicting.

My wheels are laced with 14 ga spokes, but if I did them over again I would be using 14/15 db. Both
the rims and my XT hub have been trouble/maintenance free for the past two years. I should add that
I'm only using the XT hub on the rear wheel because my bike came stock with a Real front hub. Both
hubs have been great.

Rather than mess with the bike, take a look at an aluminium frame rucksack and specialize it for
carrying your gear,

Would make for a hell of an endo yikes &^@(&#

If you really want a new wheel, I'd vote for Sun Rhyno Lites with a Shimano XT hub. They are readily
available here in the US for a reasonable price.

I would assume you can get them there for a good $$ - not sure you could get the 1.5 tire on it
though. Check with your dealer. Maybe get a bigger tire? It would help.

You could buy 3/4 of these wheels for what you'll pay for a CK wheel.

I've spent most of my money on mountain biking and windsurfing. The rest I've just wasted.

If I were you, I'd look for a deep rim (~30mm) like the Velocity Deep-V and build it up with an XT
hub and 36 14-15 butted spokes, three cross. That'll give you plenty of strength, a relatively light
wheel, and won't cost a fortune either. The deeper rim will flex less under the load, and will
better distribute the load to more spokes. Just make sure and keep plenty of pressure in those tires
so the rim never bottoms out.

Yes, Yes, I know. It won't happen again (probably). My knuckles still hurt.

I got that suggestion once and built a wheel around it (an old Campy mountain rim from a wheel
builder's stash -- a k2, it think). The wheel was strong, but the problem was getting the long stem
tubes needed. Created a real PITA. Presta extenders are tough to find and almost worthless and long
stem presta tubes are almost as hard to find and costly (in mountain bike sizes)!

Yep, they built my current XC wheelset to my exact spec and I can't fault them for anything. Good
service too, friendly people to match good prices! Wheels are still perfectly true after 18 months
of abuse on the trails. Mine are Mavic 519s on Deore hubs, but I don't lug all that throwing
equipment so I can't comment on there load bearing ability!

Good luck. Mark

Hi all, thanks for your recommendations - Im going to go have a chat with some of the bike shops and
see what they say. I'll consider getting a trailer, but given that drivers dont even give you enough
space for a bike, a trailer may cause me different problems.

Thanks, Barry
