Oklahoma everywhere Bike Setup:
Economical carbon fiber (old gas pipe style) with 36-52 crankset and a blend of Ultegra and 105. The wheels are set up with Sapim spokes, 24/20 but I should have used something softer at the front, like Wheelsmith or DT Areolite.
It didn't climb well until the IRD Cadence 19mm were installed. Summary:
I bought these for the purpose of easier hills. They're box rims, yet somehow more beautiful than average. That's IRD Cadence 19mm or Speedcific Niobium 19. They are much stronger than advertised. Less than 400g is true, with the symmetrical at 392 and the offset rear rim at 386.
These allowed me to remove the triple crankset and use a double crankset instead. Yes, they are effective. I also used DT alloy "stronger than brass" spoke nipples, which is appropriate for a "climber" style wheelset.
The purpose, of the small size 19mm Cadence, is easier hills, and they do it well. Thank you IRD!! Strengths:
EASIER HILLS!!!
Strong!
Shiny!
Higher average speeds than tall metal rims, because of faster hills.
Black or Silver
Available in a wide variety of spoke counts.
Everyday for road or race-day for CX. Weaknesses:
Not a weakness, but a funny caveat:
It is possible to underestimate the strength of these rims and get your front wheel too tight and cause pogo--the rims are way stronger than advertised, so build accordingly to tension and/or load-bearing for larger, stronger, rims. Unadvertised extra strength is the problem. There's no weakness. Similar Products Used:
Very high end Mavic 700c, Velocity Areohead 650B, Velocity Synergy 559-Mountain. . .and what else is really strong at about 400g? There's not many similar "climber" rims like these. Short metal rims are much faster uphill than the popularist tall metal rims.
