I've never had a problem with my good old aluminum Zefal HP (the 70s version) direct-to-valvestem frame pump. I've had one on my Fuji since '76! Yes, it does take a bit of effort to get to 105psi, but I'm still riding on 27x1-1/8 (that's 28mm) tires. BUT from home I either use an air compressor or a floor pump. I only use the frame pump if I have a flat on the road. The trick I've learned over the years is to use my off hand to hold the head of the pump AND I wrap a couple of fingers around the spoke(s) near the valve stem. I've NEVER torn a stem that way...
