Questions for you Pro wheel builders - I just had some Kinlin XR-19W rims laced to BHS hubs with 24/28 lasers built by a local shop - as I have yet to enter the wheel building world. I am around 185 lbs and had no problems with old Cane Creek Volos 24/28's, or Campy Zonda's for that matter. Front wheel is great , however when I go to drop the hammer, the rear just dosent transmit the torque to crest that hill or power the flats. They spin fast but I cant muscle my way up a climb like I used to. I guess I should have gone XR-300's but:
I wanted to check spoke tension first - what should the DS and NDS tension be? NDS spokes feel quite low in tension...
Would it make a difference to rebuild with 'Race' spokes instead on both DS and NDS?
I was worried about this problem on these rims. They are only rated to go 105 kgf for max tension, which definitely makes me a bit skeptical. Even if upon the initial build, they were setup to 105 kgf DS, this is still low enough to where I would think the nips would gradually start unwinding.
Go ahead and check the DS tension and make sure it is at 105 or just a tad abobe. For the NDS, you aren't looking for any specific number. As long as your DS is good, and the wheel is in dish, then you should be good to go.
I doubt switching to Race spokes will do much either. If getting the rear back up to proper tension doesn't change the ride quality, you may want to consider rebuilding to the XR270 or what not.
