98cm!?!Originally Posted by Owboduz
Alfeng,
I'm a bit concerned about one of the points you seem to be avoiding. In every review and piece of advice I have read so far, the topic of fit comes up. Bad fits can cause aches and pains, while good fits can allow hours of comfortable riding. Everyone seems to say not to buy a bike if you can't try it out first. The method you are suggesting guarantees that I would not be able to test-ride the bike and I would not be able to return it if it could not be made to fit. But you're suggesting this to a complete road newbie, who has no idea how to set the fit properly. It sounds to me like you're giving advice that is all but guaranteed to result in a less than optimal fit for someone who has no idea how to fit a bike. What am I supposed to do? Build a franken-bike, then take it down to the LBS and ask them to fit me on it? I'm sure they'll love that.
I know I'll need to learn how to fit a bike at some point so that I can make my own adjustments. But is that the introduction I need to road cycling?
As it stands, my hybrid stands 98cm high at the top tube. The handlebars rise 16cm above that. The seatpost is only raised 8cm out of the seat tube to fit me properly. This is a HUGE frame. This puts a fundamental limitation onto the fit I can get. If the top tube is too high, it limits the minimum height of the stem. Sure, there are stems that can drop below the head tube, but those introduce their own problems. If the top tube gives me too much reach, I can't fix that. If the top tube doesn't give me enough reach, I can use longer stems, but that affects the steering. So these two variables determine a lot of the fit, but there's no way for me to know if they are even close to what I need in advance.
The frame is HUGE. It contains A LOT of metal. It is HEAVY. The road bikes I tried out were 1-hand lifts. This bike is a 2-hand lift. I'm sure some of that can be fixed by replacing the rims, forks, seatpost. Some cannot.
When I ride my hybrid with Schwalbe Marathon's, I feel an enormous amount of vibration. When I tried out road bikes over the weekend, I didn't notice that nearly as much (I watched the LBS guy inflate the tires, I know they were done right). Are you saying that's NOT down to the frame? I'm pretty sure it's ALL about the frame. It's sure not the tires. It could be the wheels. It's not the seat/seatpost, since I didn't feel it in the handlebars either. Sounds to me like the frame is pretty important.
I'm not trying to talk myself into an all-new bike just because I don't want to upgrade. I don't want to upgrade because I don't think the bike is worth it. Yes, components of my hybrid bother me, but that's not the whole story. I don't like the position that I'm riding in. I tried to fix it with aerobars. That helped, but it wasn't enough. That's what made me want to look at road bikes in the first place. I only got the aerobars after I worked out that putting drop bars on the bike was going to be a minimum of £200 for shifters, bars, stem, tape, cables, etc. and that's IF I could find shifters that were compatible with 7-speed Shimano Tourney. NOW I know that deciding not to put drop bars on was a good idea, since I would have had no way to work out adjust the bars to fit me properly.
In summary,
[*]I don't know how to fit a road bike.
- The frame is too heavy.
- The geometry is bad for road cycling.
- The components are low-end.
- I can't test-ride it if I'm cobbling it together myself I can't determine whether the parts I order are going to work or not in advance
[*]It can be useful to have two bikes, like when one is fitted with a big rack for carrying groceries, and the other is fast.
Yes, it's a savings. Yes, it's doable. But is it the right choice for me to convert my hybrid to a road bike? There, I just don't think so.
Really?!?
Well, I do not recall your saying before this that the frame was the modern equivalent of a Penny-Farthing ...
- maybe you could-or-should post a picture of your current bike as it is set up
- what is the length of the virtual Top Tube?
- I don't recall your mentioning your height, BTW ... a 40" tall Top Tube would seem to suggest that you must be over 6'6" tall if you present abstract information, you probably should not expect better answers, BTW
Regardless, I fully understand that a typical Hybrid probably weighs in at 15kg, or more ...
BUT, an alloy frame typically weighs about 3lbs (1.4kg) ...
MANY Hybrids, particularly at the lower end, have a lot of steel components ... a lot!
Figure on at least 6kg worth of difference between the steel components & alloy components ...
If you have a Suspension Fork, then I reckon that it has to add at least another kg-or-two because it probably has steel lowers.
And THAT is why I indicated that the pictured Mongoose weighs less than 20lbs. (9.1kg).
REGARDLESS, I was working from the apparently false presumption that the Hybrid you had FIT YOU ...
- if it fit you as a Hybrid, then it can be fitted to you as a Road bike
- if it was too large for you as a Hybrid then (other than the fact that it should not have been sold to you and/or you should not have bought it!!!), then you are correct that it will be difficult to convert it for YOU to use as a "Road" bike
Vibration? There may be a problem with the Headset adjustment OR your front-and/or-rear wheels need to be trued OR the cones need to be adjusted ... just to name some possible causes.
