With Rocket Rons too - using Furious Freds would've been cheating, as they're only usable about 5 days of the year!

Been riding it since December, but with a few little changes it's now happily under 20, which I'm chuffed with!

Spec is:

-OCLV carbon frame, RP2 shock
-Fox Float RL FIT Remote fork, tapered steerer
-A2Z hubs/Podium MMX rims/Revolutions (1246g with yellow tape and valves)
-XTR M980 groupset including brakes
-Custom Mathias Hellore titanium 36t chainring and bodged chain guide
-KCNC 160/140 rotors, now with Ashima alu rotor bolts
-New Ultimate stem
-X10SL chain
-Bontrager seatpost/saddle
-Mount Zoom bars, titanium bottle cage, skewers and top cap
-Egg Beaters with ti axles
-Alligator I-Link cables
-various alu and ti bolts

It's rather fast. I like it a lot. Anyone in the 'your scales are wrong' camp is more than welcome to have a heft at Mayhem next weekend - I'll bring the scales too! Still need to get a few more alu bolts, want to make a new cage for the chain guide out of carbon too. Not a huge amount else I can be bothered to do though!

Good work, those Mt Zoom bars are a bargain.

Just what I was going to ask.

impressvely light but butt ugly, scrape the paint off and it'll be even lighter!

Agreed, their ti bottle cage is nice too, lighter than the Race X Lite Carbon it replaced and it doesn't mark bottles!

Jesus that's impressive - how does it ride?

Quickly! I love it to be honest, I'm used to racey bikes, and it's just so fast. Shame about the rider really.

Certainly splits opinion, can't say I'm that fussed either way!

It's a weird satin paint which is much thinner than normal, it scrapes off if you look at it strangely!

Yep! It's a Superstar BB mounted guide, a DMR seat tube clamp (£3 off CRC) and an offcut of carbon! I originally used some rack stays which worked well, but were a bit flexy. Impressed with it though, never dropped the chain, raced and ridden it all over the place!

It looks good, I have the superstar chain bit, Right aim going to copy you cos I like it and it's a hell of a lot cheaper than those e thirteen and mrp devices.

Posted 11 months ago #
njee20 - Member

Agreed, that was why I did it. Alternatively I think Superstar may be about to do a seat tube mounted one.

squiff - Member

Am just trying to work out what size DMR seat tube clamp I will need, think i need the 34.9 clamp???. Am wanting to get it done before MM next weekend if I can.

There must be a good couple of kilos in logos and logo paint. Could cut a couple of cms of the brake hose, bars are too wide and the saddle appears to have some kind of padding...
This Mountain Mayhem of which you speak, does it have any mountains?

Where's the commitment...

Cut down the steerer and loose the spacer, switch to SIDs without lockout, loose the bottle cage and computer mount, 160 front rotor,cut down seatpost, lighter saddle - I'm sure there's a bit to loose yet

Posted 11 months ago #
njee20 - Member

I do want to switch to a crown mounted lockout, they don't do 100mm SIDs with a tapered steerer in the UK, I was planning to swap, and remove the lockout! I could trim the steerer, affects resale value!

Bottle cage stays - not drinking tends to slow one down in races! Computer mount is a bit pointless really, but I like all the data! It is a 160 rotor, seatpost is at it's shortest, saddle is a surprisingly light 150g. I used to use SLRs, but they don't last.

Not doing badly though

This Mountain Mayhem of which you speak, does it have any mountains?

No, it's a load of muddy fields and a course I'd never consider riding outside the event, but as it's the single biggest MTB event in the UK I don't really care, it's a lot of fun! You're right on the hose - there's another couple of inches in the top tube I need to trim! Like the saddle (see above!) so that stays.

It's gotta be usable first and foremost, I trust all the parts on it. Could save some extra weight, but IMO it's either too expensive to justify (XX cassette) or would compromise performance (unpadded saddles and what not). Certainly happy with it more or less as is for now!

Is this your only bike?

I have always found light bikes horrible to ride unless you're racing, no fun whatsoever.

Posted 11 months ago #
njee20 - Member

Only MTB yep! I love it! Got some Hope Hoops on Crests for when I'm not racing, but prefer the lighter ones. I think light bikes have come on significantly in the last 5 years or so, it handles extremely well, plenty stiff enough. I find it a great trail bike, personally I find heavy bikes horrible, it's what you're used to frankly!

Could shave a few grams off with a sensible length stem

Good effort, well done. My bike is perhaps 8 or 9 lbs heavier than yours, but having saved 8lbs off my old bike I now totally see the point when done right

Posted 11 months ago #

100mm's not that long! Only 102g too!

102?! I'd be so scared riding stuff that light, but then im a bit clumsy and tend to hang on and hope

Posted 11 months ago #

It feels perfectly stiff (to mr at least!). In fact there's an appreciable difference in front end stiffness compared to the 2010 one, guess tapered steerers really do help!

Looks nice mate, well done! What I like and find the most impressive is that you have achieved a significant weight saving with fairly ordinary parts. Nothing out of the ordinary or overly exotic. The bike looks like you can still ride it day in and day out with its intended purpose in mind, unlike some of the light bikes I have seen.

just out of interest how much do you weigh ?

looks good, recently built a sub 20lbs bike myself, but hardtail and I have to sub carbon rigids to get the 20lbs. I've come to realise that a light bike gives me a much more enjoyable day out for a not very fit person, rather than lugging round a hardcore mince tank, just to go a bit faster on the downs. Strangely, I'm now almost looking forward to the climbs. I've still got the big bikes, but just for playing on, blasts in the local woods or occasional trips to the Lakes. By comparison, they don't see the light of day very often now.

You had a 2010 one then bought a 2011 one?

njee, are all the carbon Treks coming with tapered headtubes now? I'm waiting on a warranty on my 2009 elite 9.9ssl.

What does that mean to my current fork, can I use it as-is?
