The Top Tube on the Langster (a 56 frame) is 73.25mm. According to the calculator at competitive cyclist, my top tube should be 53.7 to 54.1. That's what leads me to believe that a 51 Leader 725 would fit me far, far better than the Langster.

Yeah...you may want to measure that again.

sinikl 05-27-13 07:45 AM

I assume he got that number from here http://www.google.com/imgres?imgurl=...9QEwBA&dur=167, which has totally crazy measurements listed for all sizes of Langster. I think maybe they have head angle in the TT length column.

Scrodzilla 05-27-13 07:50 AM

That makes sense (but it doesn't). The head tube angle is listed as 588 - which I'm assuming is the top tube length - but who knows it that's the actual or level measurement. Whip out the tape measure, boys.

Jemi9OD 05-27-13 10:30 AM

Close - I got it from the Specialized site at http://www.specialized.com/us/en/bik...wyork#geometry - I'll measure it next time I'm in the office though.

[EDIT] Oh god, now that i look at the rest of the measurements on that page, I completely assume Specialized was smoking something. [/EDIT]

When I was planning to sell the bike, I measured the top tube (horizontally, to seat post) as 22.5", or 57.2 cm.

Scrodzilla:

Newb. Want something for easy rides with my kid and (sometimes) a 2.5 mi. flat commute to work. I am lazy; Want my bike to be like a toaster: Get up in the morning, and it just works, with little hassle. No long trips, no racing, etc.

I was planning on getting a BD Hour or similar. Then a friend offered me an old bike of theirs: an early-90s Cannondale R500 in very good shape, that hadn't been ridden in years. I like the no-shifters ideal (I have no need to go very fast, and like the simplicity) and appreciate the value of getting something newer. But the Cannondale is a very good bike, too. Both are similar price.

Which would *you* buy?

Added: The Cannondale fits me fine; I'd get the BD in my size and get it assembled/adjusted at the LBS (as I would with the Cannondale).

Scrodzilla 05-28-13 07:00 AM

One thing to take into consideration is the Cannondale will have vertical dropouts, which means unless you plan on running single speed (freewheel, not fixed) and using a chain tensioner, it may not be the best choice.

SinX7 05-28-13 09:52 AM

Hey Scrod, I'm looking for a new tires (Size 23) what do you recommend? Mainly use it for commuting and daily rides. I prefer a tire that have a good balance of protection while still giving me good speed. What do you recommend?

Thanks!

I read his post to mean if he got the cannondale he would keep it geared. Hence the "i like no-shifters... BUT the cannondale is a good price"

Optimus 05-28-13 11:44 AM

That's correct; I'd keep the gearing on the Cannondale.

(If it has downtube shifters that I never use, can I be an honorary SS/FG member?) :rolleyes:

Scrodzilla 05-28-13 12:20 PM

Oh. It shouldn't even be a question then. The C-dale will be a much better bike than anything offered by Bikes Direct.

So yeah, the top tube actual horizontal measurement (center to center) is 57.2 cm, while the top tube measurement itself is 55.2 cm. The Leader 725 is 54 cm; I suspect that would fit much better.

Scrodzilla 05-29-13 09:57 AM

I think you'll benefit by using a fit calculator (if you haven't done so already) and basing your decision on the top tube.

CyclingDaily 05-29-13 04:57 PM

Dear* Scrod: Which do you prefer and why?
1. FSA track pro chainring vs Sugino ZEN chainring?
2. Vittoria Randonneur vs Continental Gatorskin vs Panaracer RibMo?
3. Thomson X2 vs X4?
4. Toshi double straps vs MKS fit-alpha double straps?
5. 32H vs 36H wheel
6. Push heavy gears vs spin fast?
7. Aluminum frame vs Steel frame?
8. Ascending vs descending a hill?
9. Opinion on 2013 Leader Kagero frame?
10. Opinion on Miche Pistard wheel set?

Scrodzilla 05-29-13 05:15 PM

Seriously? Are you sure you didn't leave anything out?

Mumonkan 05-29-13 05:31 PM

83 vs 84% humidity?

I'll come up with more questions later on! :thumb:

Reads like two "Top 5" lists:

The most dipsh1t questions whose answers are based on the opinions of others that I am too lazy to research for myself and decide which might be my best personal choice.

Scrodzilla 05-29-13 05:52 PM

CyclingDaily - have you dialed in your saddle angle yet?

Yes they are at 0 degree now.

I believe he was.

I don't mind answering questions but I'm not going to do all your thinking for you regarding such elementary things as whether I prefer riding up or down hills. Use your own brain.

CyclingDaily 05-29-13 06:03 PM

I like riding up hills where I used to live, challenging but not impossible.
And I didn't know retrogression shipped to Japan !

striknein 05-29-13 06:19 PM

What reverse levers fit in RB-018 bars? Can't get a ****ing straight answer anywhere. Also, are they 22.2 or 23.8 diameter?

I'm not asking him "What should I get?" I'm asking him what his personal preferences are.

I could use a water cooled saddle.
