I'm a big Blackspire Chainring fan - I've run the Mono Veloce on all my SS cranks and run the Super Pro rings on my 110/74 RF Turbines. Current setup is 24/34/Bash on my Sultan w/ an 11-32 out back.
For the next racing season, I'm thinkering of going 26/38 with an 11-34 - however, I don't see any 38T applications aside from the Mono Veloce SS ring.
-- How crappy would the shift be to a 38T ring without the ramps and pins?
-- I also run a medium cage XO - I assume it'll be close max capacity as I calculate a 39T capacity requirement using SpeedubNate's [IMG]excellent tutorial[/IMG], and the 'conservative' rating on SRAM med cage mechs is 37T.
Then again - I could just get the 36T Super Pro ring w/ shift pins which nets me a 35T calculation and run 24/36 or 26/36. This option seems more 'doable' since I'm not finding a 38T Blackspire Super Pro.
Who makes good, durable and lightweight 38T rings? Stronglight does I believe - just don't know much about them or where to source them in the US.
