Power to weight ratios

Postby richeaf » 21 Apr 2008, 9:12pm

Dear Bikers-
I have a natural desire to carry as little extra weight as possible!

My last bike was a whippy little Carlton Corsa(? )road bike which I regularly reached 35mph on down Whitehall when at Uni..

25 yrs later I need a fun bike to enjoy off road with the kids but these MB contraptions always feel terribly heavy to me!
What is the weight range for a competent Mountain bike or Hybrid - say up to £400 of beginner's (or second hand) kit
perhaps a hybrid would save a little of my energy??
Is it normal to get weight quoted in a shop for a MB these days

Most MTBs are around 27lb these days - any weight saving has been spent on front shocks. Downhilling machines are well over 30 - generally 35-40lb!

If you want a lighter bike then buy a set of rigid forks and get them fitted. Kona Project 2's are a general favourite.

If you want a really light MTB then go for one made in the mid 1990's - there are planty of quality frames around, especially old Marins and Konas.

try www.retrobike.co.uk for its for sale section...

More importantly,what do you weigh?

I only weigh 12 Stone. I saw lots of nice new off the peg bikes on the Dawes website last night from 12-15kg. (25- 40)
I guess if you don't have the suspension in the forks you need a quality frame is it?
I will go to that site-

what say you reohn 2 ?

I'm sorry your last sentence doesn't seem to make much sense,perhaps a typo?
MTB's are going to be quite a bit heavier than road bikes due to having to withstand what they're built for unless you're spending quite a bit of cash.

I'd take a long look at Dawes's frame warrentee's if I were you before buying.

Cannondale springs to mind (good warrentee's on frames)and a good company by all accounts.

have a look at the Specialised Sirrus hybrid bike.

i bought mine (basic model) 2years ago for about £400...so it might even be cheaper now, yet they are still being produced new.

ive fitted mine with 700x23c tyres, changing from the 700x38c they give you.

its a great bike...and i do about 20miles a day easily on it!
