We posted about the new 1.2mm Power Cordz derailleur cables earlier, but had a few followup questions for their man Phil Vega:
Are they shipping now? Yes, all models are in stock.
Are those little rubber seals on the ends of the ferrules? The seals are made of a slick nylon.
Do you make longer ones for tandems? We’ve made them in the past, but the demand isn’t there.
Is there anything special about the housing, or is it just the cables that are unique? The 4mm housing uses a Teflon™ liner with a high quality water-proof grease, The 5mm housing uses the same liner and is also Kevlar reinforced.
According to their website, it’s $36.95 for just the cables (set of two) and $69.00 for a full set including the housing and ferrules.  According to Phil, they’re moving fast.
