I'm a relative newbie to this Weight Weenie lark and although my steed isn't ever going to be as light as some of the 'WeightWeenie' steeds I'm still keen to loose a few g's where I can. Which is where you guys/gals step in, hopefully...
My beastie is a 2002 Marin RockSprings and I've already replaced the saddle (light-ish Specialized BG), seat post (Thomson 0 layback), bars, grips and tyres (kevlar Panaracer Trailblaster 1.8's) and as my std Deore shifters were playing up I've just upgraded them to LX.
Over the last couple of years, I've been trying to replace bits with lighter kit and recently found that the new Trailblasters made a fantastic different to the ride over the original WTB Motoraptors. Shaving around 1lb+ of rolling mass along the way.
As my tyre swap was so beneficial, I've been thinking about replacing my wheelset. With your help, I'd like to quantify if my standard Marin ovation, disc (cup/cone) hubs with Mavic X139 rims are really as heavy as I've measured them! While changing tyres, I simply dropped my std wheelset (including qr's, hope disc's, cassette) onto the scales and saw around 2,000g on the front and 2,500g on the rear, which comes to around 10lb in total!!! If this is true then it equates to roughly 1/3rd of the bike weight...
To match my measurements to a Weenie listing I've roughly calculated that my standard disc hubs/X139 rims (minus all the guff I included above) come in at around;
Total 3,760g = 8lb
Looking at the WeightWeenie listings I see that Hope XC, disc hubs with X517's come in at around;
Total 1,709g = 3.7lb
Can I really save around 5lb just by replacing my wheels? I'm not looking for an exact comparison on my kit but any experiences that you've had of suggestions on what make good XC wheelsets that are available here in blighty.
PS: A lighter and shorter stem is on order from On-One (80mm, 135g, std Marin = 175g) which should help to equalise the differences between/panic! when jumping from my MTB to my commuter
My zero layback, Thomson seat post deviated from my 'replace with lighter' strategy as it totally transformed the ride and handling...for the better!
