Mountain Bike Weight

[dave123456]

evening,

been cycling for a number of years, started back in the 90's when bike weight was a big thing.

I have always been a relatively smooth rider, and back in the day raced on a 92 trek 8000, and with a few upgrades (use seatpost, Royce bb, campag rims and hope hubs, air b inner tubes and ritchey wcs 1.7 z max) managed to have a cross country race bike at around 24lb even with rock shox mag 21s on....

fast forward 20 odd years, I have a cotic soul frame with rock shox rebas and it feels heavy. admittedly we are now lumbered with disc brakes etc but what should I expect to get a 4.4lb frame down to on a bike...

I'm running Thomson seatpost / stem, bontrager wheelset and it feels sluggish....or maybe i'm getting old!

thanks

Hello,

Just reading that was funny as its exactly what I am doing.

I did have a Cotic Bfe frame with Revelation 130mm qr forks, Thompson post carbon bars and Bontranger wheels 1x9 gears and recently decided it was too heavy and this is the reason my mates keep beating me :-)

I have now bought a Soul frame, new Rebas and just saving for some Stans no tube Arch EX rims and Hope hubs, I will also go from 2.2 to 2.0 tyres. Hoping for just under 12kg.... Should be about 1 kg lighter than my Bfe build :-)

As she is without the Reba and new wheels, already feels quicker. I have took off the chain guide too and fitted a Hope retainer ring.

very nice bike, but I would say that....

I was ammused when a friend built up a new titanium Cotic soul with XT kit and lots of nice bits to find that the final weight was 11kg, which was 500g more than my 1998 stumpjumper M2.

But when I built my new yeti ASR5 (26") I was impressed that it came in just 0ver 11kg so that was only 500g more than the hardtail

I had a 96 stumpjumper m2, very light and very fast.

Makes me feel sad sometimes that my XC bike is about 20kg when built up for summer uplift-serviced trails and 17kg in proper XC mode. 2009 Giant Reign X1, standard except a KS Lev seatpost and 650lb spring. DH tubes and tyres are the summer tyres, and the XC build uses 2.25 ADvantages. Generally I run a 2.5 supertacky DHF in the front and the ADvantage in the rear.

My DH bike is 16 kg though, and that can be dropped by another 2-3 kg if I went to air springs.

I'd like to have a nice light enduro bike, but at 90kg I'm never going to be an uphill demon!

20kg??

[dave123456]

90kg of body weight, 40kg of which is quad muscle..

[dave123456]

as it was puzzling me I weighed my bike. 27.25lb...which seems a bit heavy....

so

Frame: Cotic Soul medium (c2000g)
Fork: Rock Shox Reba SL 2006 vintage (c1600g)
Stem: Thomson Elite (c160g)
Handlebar: Answer Pro taper (315g)
Brakes: Hayes Stroker Gram (670g)
Shifters: Deore XT 9 speed (260g)
Rear derailleur: Deore XT 9 speed (270g)
Front derailleur: Deore XT (??150g)
Chainset: Deore LX hollowtch (???)
Seatpost: Thomson Elite (c250g)
Saddle: Selle Italia Turbo (c270g)
Wheels: Bontrager Select (?? no idea)
Tyres: At the moment Schwalbe Sammy Slick (980g)

Can't think of anything else...cables, BB, chain, grips...

so, anyone see an obvious area for improvement?

Knocked nearly 2 lb off my Whippet by upgrading the Bonty wheels that I had left over from my Trek....

do you mind me asking which trek they were off? mine were off a fuel ex-7 and I suspect that they may be the millstone!

[dave123456]

that looks good..

I have decided on:

ztr crest wheels, dt revolution spokes, hope hubs and tyres unsure... any tyre recommendations gratefully received..

[dave123456]

decided to go for the below...

what decent lightish all rounder tyres have good recommendations? would like a fairly simple winter trail tyre, not a real mud plugger, but something capable in wet conditions.

REAR-WHEELS-DISC-HOPE
•Rear Hub Hope Pro 2 Evo 135mm Quick Release
•Rim ZTR Alpine Black - Disc
•Spokes DT Revolution Silver


FRONT-WHEELS-DISC-HOPE
•Front Hub Hope Pro 2 Evo Disc - Quick Release
•Rim ZTR Alpine Black - Disc
•Spokes DT Revolution Silver

bought the wheels and fitted them this weekend. went for continental x king tyres and the difference is astounding. thoroughly recommend the ztr rims, decent weight and price.

I have some X Kings folding tyres on my Trek 8500. Absolutely no grip on any damp surface, and don't try them on wet tarmac, that is super scary.

thought it was me on the wet tarmac...hadn't been out since before Christmas and thought i'd lost my bottle! I have some bontragers that are ok in mud.

Bike weights are always a funny one. Some bikes hide their weight well, some don't.
