Body weight limits for lightweight road frames(8 posts)

Body weight limits for lightweight road framescossington
Jan 29, 2003 10:18 AM
I'm looking to buy a new road bike/ frame. I am concerned whether the lightest Al frames (eg Scandium/ Starship etc) will be suitable, as I weigh around 220 lbs (100 kgs).
I'm looking to spend around £1,000-£1,200 (circa $1,600 to $1,800) on a frame. One option seems to be a Colnago Ovalmaster (6/4 Titanium).

Can anyone suggest any alternatives, whether by bike manufacturer/model or by generic tubing type.

Go with a 3 to 3 1/2 Lb aluminum frame or a 3.75 to 4 Lb steel frame.
If you go with aluminum, look for 7000 series Al. If you go with steel,look for Reynolds 853 or another steel that hardens when welded. If you give up 1 1/2 Lbs to get a stronger frame, your total body and bike weight will be .6% heavier than the super light bike.
I'm not sure if a titanium frame would be right for you. If you decide on Ti., go with a heavier frame.
No way.russw19

The titanium frame you are thinking about is perfect for you. If you look at a Ti frame, the OvalMaster or the Litespeed Vortex are the best choices for your size. Both of these frames are far from being called "ultralight" and both are 6/4 titanium alloy frames. For the amount of power you are going to produce at your size, these bikes will suit your needs just fine. They will be plenty stiff and strong, yet compliant enough to let you ride all day. I am telling you this from experience. I am 6 ft. and 215 lbs. I own an Ovalmaster, and it replaced the Cannondale that replaced my Vortex. The OvalMaster is reasonably priced for a Ti frame as well. Just make sure that you stick with the Flash fork for your size. Or don't order a fork from Colnago and order the Time Millenium Stiff fork instead. All Colnago's come with a 1" steerer tube, so you may even want to get a Nivacrom steerer for your fork if possible. But at your size, don't get a carbon monocoque (carbon steerer) fork for this frame. It won't be stiff enough as Colnago hasn't yet embraced the 1 1/8th steerer tube. The Ovalmaster is not a lightweight frame, and it's not intended to be. It weighs in around 3 1/2 pounds for my 58cm. It is intended to be strong and smooth and is specifically built for heavier or stronger riders. One other bike you may want to look at is the Pinarello Opera. It is the sister bike to the Prince, but it is a Steel frame with Carbon stays, whereas the Prince is Aluminium with Carbon stays. Over all it is still pretty darn light and very comfy, even for us big guys. I currently have a Pinarello Paris (which is now the Marvel) and it holds up fine for an aluminium frame as well. But, like the OvalMaster, it's no lightweight champion. If you are a bigger guy, build sensibly and you will be happier in the long run. Lightweight isn't for us, but I bet I would smoke Pantani in a sprint.

At your weight, I'd seriously avoid an aluminium frame - it will be either so overbuilt as to provide little flexibility and resilience or alternatively, will be too underbuilt to provide decent fatigue resitance. You've rightly identified the Ovalmaster as a good choice - and Mike at Maestro will probably give you the best deal around - but you will have to wait awhile for Colnagos at this time of year. An alternative would be to get a steel frame in Deda Eom16.5 or similar - it builts into a pretty lightweight bike which will easily outlast any ally alternatives. You could also have the luxury of a custome build at that frame price. If you're in the UK, either Chas Roberts, Dave Lloyd, Terry Dolan or Pete Matthews spring to mind.
how many frames have you researched?ColnagoFE

The lightweight AL is a bad choice IMO. The ovalmaster might be more appropriate, but these 2 types of frames are so different I wonder how much research you have done to get these 2 options? You'd also do OK with something like a steel Merckx MX Leader or the Colnago MXL. Just don't get anything super light at 220 lbs. 36 spoke wheels would be a good idea as well.

Stay away from ultra-lite aluminum frames. The Colnago Ti frame may be a good choice. I am 220 now, but when I bought my Colnago CT-1 last June, I weighed 230 lbs. I have never had any problems with frame flex or durability. I have the full carbon Force fork and FSA carbon fiber cranks. I also use Ksyrium SL wheels and they are rock solid. All together, with pedals and bottle cages, my bike weighs 16.1 lbs. IMO just because I weigh a little more doesn't mean I have to have a tank for a bike. You just have to do research and be willing to spend some money for well built equipement. BTW, on my old lugged steel Scapin I used two different sets of 32 spoked wheels. I had to have two sets because I broke spokes on a weekly basis. I think the quality of the rim and hub matters more than the spoke count.

I wouldn't consider any frame less than 1.3kg. Deda SC61.10 tubing is pretty light and very strong. But stay away from Deda V107, Deda U2, Deda EM2 tubing.

Ti's a good choice and the OvalMaster is an even better one.

Steel is the strongest but the thin walled Columbus Foco and Deda EOM 16.5 tubes have their limits that don't differ much from lightweight AL. Strong steel frames are too heavy, IMO.

Get a good set of Mavic Open Pros with minimum 32 spokes and consider going with 36 spokes in the rear. I've been told that the Campy Nucleons are a very strong wheelset that can stand up to heavy riders.

My weight fluctuates from 200 to 190 in the cycling season. I have a Deda SC6110 frame with Campy Nucleons and have experienced no problems for the last 2 years (4k miles) with the exception of one popped spoke at 1k miles on my rear wheel.

Look into Orbea(Spain)Aluminum frames with LT warranty.
