Bike Buying Advice

I'm thinking of buying a Specialized Dolce D4W 2006 road bike. I'm 5'3" (160cm) with a 29" (75cm) inside leg and not sure what size to buy.

I know I should get fitted properly in a bike shop, but at the moment it's not really an option.

The shop has a 48cm or 51cm frame and am not sure which one to go for.....

Any advice would be appreciated Very Happy

MJ. You dont need a pro bike fit...but your shop should be able to help with getting you on the rioght size frame.

basic things to consider:

1. your legs should not be fully extended at the bottom of the stroke.
2. with your hands on the hoods, look down at the front hub. a decent fit would have the hub blocked by the handlebar
3. your body knows. give each a good test ride...and not a spin in the parking lot. you need to get a strong effort in. you should not feel too stretched to reach the bars.
4. standover height...not too meaningful, but be sure you have some clearance.

Thanks for advice Headwind, much appreciated.

I'm buying the bike on-line and I know nothing beats actually testing the bike but there are none of them about in the shops, well, not over here in Holland.

From what I can tell, I fall inbetween a 48cm and 51 cm frame.

Is it better to get a bike that's slightly too big or one that's on the small side? I'd rather go for the bigger bike as I do have concerns about my feet (OK, they're only Size 5, UK) overlapping the frontwheel when turning.

Jeez, I've coped with second-hand, hand-me down since I was 13, I think I could cope with this.....

Thanks again Headwind.
Very Happy

no sweat. heres my recommendation. look the geometry of the bike you are buying up on the web. pay particular attn to the top tube length (measured from center of head tube to center of seat tube on a horizontal plane...carefiul of compact frames) and not the stated frame size (measured differently by different manufacturers). go to your lbs with those numbers and hop on a frame of comparible size...

without getting on a bike its hard to say.

I wouldnt worry about front wheel strike. A shorter top tube can be extended with a longer stem and a setback seatpost...if its too long, its harder to shorten, in my experience.

I used the following guide when working out my "optimum" frame geometry, so that I could ask my LBS to get hold of a suitably sized bike for me to road test. It served me pretty well.

As mentioned above, go to the Specialized web site (or retailers' own web sites) and get as much information as you can about the frame geometry to compare with what "ought" to fit your body. I see you're looking at the 2006 model - I'd reckon that the Specialized web site will only have details of the 2007 model (will they have changed that much?).

Hope this helps... Confused

Good advice AA. Rmemebr there are a number of bike fit calculators, and they can generate different numbers.
