    These are the must have items:

    – Minimum 140mm travel
    – Aggressive trail geometry, so around 67 degrees HA, 13.5″BB as a guideline (not buying on the basis just of geometry)
    – Rated for at least a 140mm fork, ideally a 150mm fork with 160mm a bonus.
    – Capable of medium sized gaps/drops, say around 3-4m on a gap, 2m to flat.
    – Weight (the really important one) cannot be in excess of 2.7kg (6lbs) with an RP23 or similar. Ideally it would be 2.5kg (sub lbs). Bike weight with absolutely the lightest build possible should be aroiund 26lbs or less.

    The good news is there is no restriction on budget, so carbon exotica are in the mix.

    Bike use will be aggressive trail riding; fast singletrack, trips to the Peak/Wales/Chicksands maybe a few DH courses thrown in. Home turf is Surrey Hills but the rider (it’s not for me) is doing most of the bigger jumps and drops around here.

    I’m curious what fits. It’s for a mate who currently has a Five Spot but wants to lose weight from the bike. He only weighs 60kgs so there’s no opporutnity for him to go on a diet! I’ve been trying to suggest things but we’re running out of ideas other than a Blur TR-C or a Mojo SL-R.

    Pivot Firebird or a Pronghorn PR6 Trail with a 36 Fox Float. Except we all know no-one will ever accept that the Pronghorn is epically good simply because it looks a bit special, so just pretend I only said Pivot Firebird.

    It’s not the Blur TR-C you want, it’s either the LT Carbon or Nomad Carbon. The TR-C is only 130mm travel and 130-150mm fork.

    LT Carbon is 140mm, will take a 160mm fork and weighs 6 lbs
    Nomad Carbon is 160mm, will take a 180mm fork and weighs 6 lbs

    Sounds like your friend doesn’t really know what he wants but…how about a Zesty 914 with offset shock bushings and a 36 set at 140mm?

    😀 Yeah may be the case. To be fair he does know exactly what he wants but we’re not sure it really exists just yet.

    The Blue TR-C may still be a contender. Current set up is with a 32mm Fox Float 150mm, so the TR-C should be OK.

    The Mojo HD has always been my recommendation and one of our group already has one but it’s not light enough for him; not compared to what he already has.

    pah – was going in with Mojo HD !

    Canyon Strive ticks the boxes and you can buy it frame only, but not sure if you can get full build for 26lb, given that their full XTR with carbon wheels comes in at 27.5lb.

    Mind you, take off the seatpost adjuster, 10 of the gears and lockon grips and you might get close, but I’d leave it all on (if I wasn’t a steel hardtail wheels on ground type in the first place).

    You could be my mate TLR but you’d have to stop making derrogatory remarks about riding in the south east 😉

    Seriously though TLR I’m a bit surprised you haven’t plucked for a Mojo HD as yet. In 140mm mode it’s probably just the bike you’re looking for.

    Mind you I also think you should splurge £70 and get a set of -7mm shock plates for the AM, then lower the Fox 36 to 140mm and set the CCDB into the third hole down at the back.

    Yes the BB is low, around 13″ off the ground, but the tune from Stendec on the CCDB is just brilliant and so far I’ve not had any issues with catching my pedals. Given where you live and ride you may still have problems, but nothing that might not be cured by switching to slightly shorter cranks.

    It’s a pretty low risk option for you to get a bike that is taughter, faster and more responsive. Switching out the Fox 36 for a Revelation would get you a 29lb trail monster and that’s still with a CCDB.

    Yeah may be the case. To be fair he does know exactly what he wants but we’re not sure it really exists just yet.

    It could be done, but I’d imagine it’ll take a very bling and non standard build. If he could get one, and that’s a big if, the stock Whyte 146 works ticks all the boxes and could be made even lighter than stated.

    RM Slayer – might be heavier than desired but seems to fit the bill otherwise.

    Yeah well he already has that. XTR 1×10 drive train, Fox 32 Floats, Crossmax STs (I still think he should just spunk the money on a set of Carbon Havens and loose, ooh, 200g!), XX cassette, carbon bars, point one stem etc.

    BTW Jimjam, are you Jambo from Sussex MTB? Did you buy the Fox forks off of me about 4 years ago? It was an eBay transaction but you popped round to collect.

    His Five Spot currently weighs 27lbs 2ozs. The weight saving options he would have over his current build would be:

    – Carbon seat post from a KSi900, saves about 300g,
    – Easton Havoc Carbon bars to replace the SixC ones, saves about 50g,
    – Easton Haven Carbon wheels to replace the Crossmax STs, saves about 200g
    – Carbon race face SixC cranks to replace XTRs, saves maybe 50g?

    I reckon he could in theory save 1lb if he made these changes, but it would be cheaper to buy a new frame.

    Very difficult to get a bike to the weight you ask for and have all the features. My Blur LTc has all the things you ask for but is 28lbs inc pedals (and Adj seatpost). And thats full XTR and Revelation WC XX’s.

    geetee1972

    Neil that sounds like an amazing bike. The Blur LTc is strange in that it weights more or less the same as a Nomad. Personally I would favour the stiffness that obviously imbues in the frame than I would the weight reduction of going with a lighter construction.

    There’s a chap down here rides a Blur LTc on the Surrey Hills with a similar build except he has BOS Deviles, Carbon Haven Wheels, Formula R1 brakes, XX gears and cassette and carbon cranks, bars etc.

    I think that gets to under 27lbs.

    yeah those wheels are much lighter than my proII’s, I also have Saint 4-pots on mine, so If I changed them to R1’s that would save almost a pound.

    Don’t get me wrong I love my bike, but to get it to the weight you quote would require too much of a compromise in strength/longevity/cost. Would you like to replace a Haven carbon rim???????

    Could your mate not bulk up a bit, put on a bit of muscle in order to be able to throw a bike around a bit easier? 60 kilos is nothing.

    Unless he’s a habitual spender of money, I can’t see the point in spending a few grand to save a pound or two when the limiting factor will be him rather than bike.

    Why not spend the money & get a few coaching/training days instead.

    26lb and 7ft drops to flat? Have you coniddered a trails bike because that all that will fir the bill surely!

    Then again, Pitch Pro this year is 29lb. Easton havens, light tyres, I-beam saddle and post is probably -3lb.

    Hob Nob if enough posh types buy this stuff it eventually filters down to us plebs. At this rate, 4 years from now we’ll be able to get 25lb 6 inch travel bikes from Halfords for £600…

    (In a less mean spirited manner, it’s pretty awesome seeing what people can build with some of the new stuff coming out, still for less than a car).

    Why does he want it to weigh less than that? Is he astonishingly weak or something? P’raps he needs a nice ti hardtail instead 😉

    geetee – i’m still keen on the ibis, but awaiting a demo from inverness shop highland bikes.
    they’re getting in touch once their demo is sorted.
    i’m looking for about a 26.5/27lb build on the 140 set-up.
    keep us updated with your mates progress and decision.

    for ref, the LTc is still on my radar…….. 🙂

    odd set of requirements- light weight is the most important aspect?

    Spec Enduro Carbon would be my suggestion, meets all the requirements on the surface, though unlikely to be boutique enough in the company he keeps/area he rides 😆

    OK the bloke is only 60kg, but seriously, what difference is 1lb gonna make overall? 😕

    I understand the point of speccing light weight components (where you’re not sacrificing strength or quality), but sometimes you just can’t have your cake and eat it. 27lb all up is still seriously light for a bike that can do all that is asked of it above, I doubt saving 1lb would make a massive difference at all… Besides, you’ve not given a full rundown of the spec, I bet that whilst there’s some nice kit in there (XTR, Fox 32’s etc.) there is easily more than 1lb that could be lost from the spec on the bike without actually spending ridiclulous money. Does he run tubeless for example? What tyres does he run, could he save a bit of weight there?

    FWIW the Maverick Durance is 1 140mm travel frame, comes in at 5.5lb inc. shock, hits the geometry req’s almost spot on (head angle is 68 degrees with a 520 a/c fork, so might be about 67 with a 545 a/c fork like a 36 or a Lyrik). I’ve had my (older 125mm travel version) for about 18 months now and I love it to pieces, I don’t huck it off things but I don’t take it easy on it either (and I’m 80kg not 60).

    Some good points in your post Mboy, largely ones I would agree with, but my mate knows his own mind, knows what he wants and is more than quick enough everywhere to carry it off.

    I did put a run down on an earlier post but to make it more easy to read it is as follows:

    g
    Frame Turner DW 5-Spot (M) 2855
    Shock RP23 280
    MISC 600
    Fork Fox 32 Float 1750
    Bars Race Face Sixc 225
    Stem Renthal 138
    Cranks XTR 526
    Chain rings Middleburn 56
    Chain device E13 XCX 55
    Chain Shimano XTR 275
    Rear Mech XTR 176
    BB Chris King 80
    Seat Specialized Henge Ti 225
    Seat Pin KSi900 550
    Brakes XTR Race 430
    rotors Shimano 160mm 200
    Wheels Mavic Crossmax SL 1615
    Tyres Schwalbe Nobby Nic 1500
    Tubes Tubeless
    Pedals Point One Racing 359
    Shifter XTR 115
    Headset Chris King 98
    Cassette Sram XX 205
    Rear skewer Mavic 50
    KG 12.363
    LBS 27.3

    I reckon there is about 1lb to save, but it would involve silly money, including Easton Haven Carbon wheels.
