Can anyone help me figure out which stem i should focus on? i have been looking at the Raceface Diabolus, Thomson X4 Stem, and Tru Vativ Hussefelt and Holzfeller Stems. Which of these is more of a fit for a 6'1 279 lbs. rider on a 06 HOO KOO E KOO. While i was thinking of switching components, thought it would be a great time to get a new headset. Looking at Chris King Steel Headset, do you guys think that the steel would be too big or long for the 06 HKEK? Please make suggestions or give thoughts. Thanks
