For whatever reason, the forum isn't allowing me to post the link for the source. But anyhow here is the info:

20" - style 214
F - 17.1kg = 37.7lb
R - 17.8kg = 39.2lb

21" - style 128
F - 18.8kg = 41.4lb
R - 20.2kg = 44.5lb

21" - style 239
F - 18.5kg = 40.8lb
R - 19.0kg = 41.9lb

21" - style 215
F - 17.3kg = 38.1lb
R - 17.3kg = 38.1lb

Hope that helped!
