I have a CBoardman Mtb FS Comp coming in at 29.1 Ibs. But my question is what's a good weight for FS XC Mtb's and what could i be looking at getting the weight down to with some reasonable upgrades.

    That's not a bad weight (I assume it's the manufacturer's weight, which is usually without pedals & using a small frame)

    Weight loss on bike can cost a lot of money, cheapest things are usually tyres (might save 0.5 lb.

    You could lose a couple of lb, but it would cost a fair bit.

    What is the spec of the bike as it is now?

    Depends on the size of your wallet, I'd say anything from 27 - 30 LBS is fine for trail riding for a reasonable budget, if cash isn't a problem you can get down to early 20s!

    Probably not with the frame he has though, I'd have thought more like 26-27lb.

    My Orange 5 weighs in at 28lb (6.6lb frame & shock) & it's got some fairly high end kit on it (X9, carbon bars, Thomson, Hope....) OK it's a longer travel bike, but unless I spend shed loads more it's not getting much lighter then 28lb.

    Yup, I'd be happy with that weight.

    My Kona Dawg is 31lbs, this is with XT/XTR and 717/XT wheels!

    It rides nice enough and is light enough to finish mid-class in an XC 'Open' race, so 29lbs should be decent for general XC I think.
  • The spec is http://www.boardmanbikes.com/mtbfs/fs_comp.html

    The weight is on a Med without pedals and the bike is standard (at the moment).

    Thanks for the advice, I'll concentrate on getting the ride right and not worry about losing any Ibs from the bike (I'll try to lose some from myself).

    Yep, sorry I wasn't referring to his bike, just what weights are possible in the 'trail' sector if money is no object.
  • The first item that is going is the RockShox Ario 2.1 Air shock as it seems to be one of the few 'let down' areas of the standard bike.

    So my next question is what i should replace it with

    thinking of a Rockshox monarch 4.2 or 3.3

    You'll need to get one with the same eye to eye length & stroke length.

    I've not used RS shocks before, I've used Manitou (Swinger air 3 way) & Fox (RP23), so cannot comment on them. The Fox RP23 is a superb shock, if a little pricey ;)

  • Ye, the RP23 is a bitout of my price range unless i can pick one up 2nd hand.

    The Swinger air 3 way is a bit nearer what i'm going to spend

    I have been looking at the new Boardman FS range and I have gotta ask why you went for the comp if you wanted to change the rear shock? For £130 more you could have bought the team version that comes with a monarch 3.1, plus better front fork, MUCH better brakes, better gears and better finishing kit. :shock:

    Seems strange not to buy what you wanted in the first place as it is much cheaper that way. :?
  • I bought the bike with the money I had at the time and the plan of only changing things as they broke but i just can't seem to get the ride right on the shock.

    Besides, by the time i've sold the Ario 2.1 the upgrade will only cost me about £50 from my own pocket.

    Oh - and i always seem to get the modifying bug.

    The spec is very even - so big weight changes are going to cost.

    Nothing obviously wrong and expensive to make it lighter, for example:

    XT Chainset - 100g saved - £120
    Rebas - 200g saved - £300
    XT 11-32 Cassette - 100g saved - £45
    XT Wheelset - at least 200g I bet - you can save another 200g on top of this if you spend more - £270
    Tubeless tyres - should save about 150g, allowing for heavier tyres - £50
    Carbon Bars - 150g assuming your bars are the Ritchey Pro Rizers, they're oddly heavy - £60

    2lbs saved for £845, hehe. Cassette would be the only obvious thing on the list, if the bike is new you won't need a new chain.

  • No, i weighed it my self on reuban heaton calibrated scales.
    Its a large 08 model

    I have just done a bit of research on weightweenies site and for a £1000 I reckon you could lose 3.5 pounds in weight

    Thing is will that 3.5 pounds make a thousand pound difference to your riding. Best to replace bits as they wear out with the best you can afford at the time and keep the scales away from your bike :wink:

    Think my bike origanally was around the 32.5 lbs mark, major change were the dt swiss wheels along with other upgrades, the forks made a major difference too, now weighs in at around 27.5lbs and flies along,well doeswhilst the chain aint constantly snapping (thats another story)
  • I just built up a Cannondale Rush thats approx 23 pounds, although it is top end gear on it. I saved a lot on it compared to paying Cannondale for the pleasure though. :D
