Most of the talk of the 55 gsm material is marketing BS. Yes it is satellite material but so is every other unidirectional prepreg. The 55 gsm refers to the material fiber weight in grams per square meter. The implication that it is somehow special is not true, you can order prepreg material in a wide range of areal weights. There is one advantage of a low areal weight, more flexibility in fiber placement. If you use 2 plies of 55 gsm material you can position them so they each lie in a different orientation vs one ply of 110 gsm material which can only have the fibers in one direction. This allows you to have a more intricate (optimised) layup for the same part thickness. But, a rim is an extremely simple structurally, which doesn't need complex fiber placement to resist the loads, but a lug for a bike joint may benefit from the added flexibilty in fiber placement. Also the OCLV acronym is redundant. Why would anyone sell a composite part that had any less than optimum compaction and low voids?
Sorry for the long post. I guess my point is to be a informed consumer and do not believe engineering done by the marketing department.
you might get lynched by some LA/Trek zealots for saying that publicly in the US
*rides a 5200 here but could care less if it is 110 or 120 OCLV*
haven't you heard? Those mono, non-lugged composite frames are unoptimal compaction high void bikes
surely the human hand pushing against the mold provides more pressure and consistency than a pressurized internal bladder pushing out against a mold
