Help me help my Clyde-Dad

Hello all, my dad would be considered a Clydesdale. Currently, his rear wheel keeps coming out of true, and a few spokes even popped out recently. I think it is because is kinda heavy, and the way he rides all the weight is on the rear. Are there any suggestions for heavy duty wheels/spokes?

Have I completely misdiagnosed the problem? As far as I know, he rides on smooth roads and paved trails, I don't think he is hitting any major bumps or anything that would knock the wheel out of true.

Thanks in advance.

Sounds to me like he just needs to upgrade to a higher spoke count wheel.

What's his current weight and what is the spoke count on his wheels now?

Is the spoke tension/ wheel truing being maintained?

He's on a hybrid. The wheel was recently trued by a trusted mechanic before it started wobbling again. Judging by similar bikes on Bikepedia, I think he has 36 spokes on the rear, can't confirm right now.

The problem is primarily a poor wheel build.

Once a spoke goes, they all will quickly follow; so just go ahead and replace them all.

If the bike does not have a disc brake on the rear; use Wheelsmith SS14 spokes on the left (non-drive side) and Wheelsmith DH13 spokes on the right (drive side). If it has a disc brake on the rear, use DH13 spokes on both sides.

Wheel build: tension, true, stress relieve, re-true. Stress relieve is CRITICAL. For us Clydes (I am a bit over 300lbs); the spoke tension MUST be very high to prevent fatigue failure of the spokes. A properly built wheel will last many years with no maintenance.
