why do guys ride sport bikes (motorcyles) with a combination of jeans, muffin top and plumbers crack?

Chombi 09-05-13 03:07 PM

Inverted drop bars on bikes:eek:....why did god ever let those even exist on this earth???!
And it exists in almost every corner of the world!:twitchy:
Curses and a pox on anyone who ever does that to a poor bike!!!:mad:

Now, there's an answer I can use. That and the '42'. Thanks guys.

I'm new to sealed cartridge BBs. I recently replaced a 124 mm spindle with a 110 mm sealed BB. Where did the remaining 14 mm go?

The same place your lap goes when you stand up, I'm guessing.

Scott,
Thanks for that heartfelt, thoughtful reply. I'll sleep easier now.
Seeds
It was, however, a serious question.

I have no idea whether this would work for Delrin, but I contacted Yakima about some cracks in my Rocket Box, and they told me to use PVC cement on them. I did, and it seems to have worked. ymmv

Seeds, 124mm is a rather wide spindle, probably reserved for triples and MTB cranks. Conversely, 110mm is on the short end of the spectrum and probably reserved for doubles or track/pista single ring cranks. In addition, some cranks will sit further out on a spindle than others. Did you also change your crankset when you changed your spindle? If you started with a double on a 124mm spindle it must have sat pretty far from the seat tube. If you are using a triple and switched to a 110mm spindle, I'd think the rings would not clear the chainstays.

Sorry about that! With some of the whimsical stuff going on in this thread, I thought it was as well. :o

I did change the crank, but just from a Silstar double to a 105 double, and from a cup and cone bb to a sealed bb. The LBS told me it was a function of sealed vs old school. It's just got me flummoxed that those two widely different lengths seem to produce the same chainline. No problems with the chainstays, which I was also concerned about.

Maybe your old spindle was assymetrical and you had it in backwards.

What size are the bolts for fender/rack eyelets.....?

On my 89 Cannondale Black Lightning, when I do an extreme turn, the front wheel hits my foot!!

Is this a symptom of a bent fork, frame or what? Should I get the frame/fork checked? The bike rides good, stiff, harsh, but good and responsive..

If you don't see any bends in the fork or frame, then the question is how big are your feet?

Because they don't know any better... ;)

I see them with tennis and shorts too.

However, to each their own. Only speaking for myself, I would never sling a leg over a motorcycle without full gear, and full coverage helmet. They couldn't pay me to do otherwise.. ;)

I wear a 11.

Also, it doesn't happen with any of my other bikes.. I have 13, two of them are in build stage, but I ride the other 11, and the Cannondale BL is the only one that does this..

THEN, it could be Crank Length, or frame geometry...so many variables before assuming a bent fork...

Ah, I think it has way more to do with your cranks than whether they're sealed or cup-and-cone. The Silstar has dead-straight arms that require a long BB spindle for everything to clear...

...while the 105's I'm imagining are curved inward for more foot clearance, allowing a shorter spindle for the same chainline.

depends. 5mm, 6mm, I once saw a rack held on with a wood screw. Also old french and some japanese bikes had eyelets for a daruma/eyebolt style attachment.

I have lots of bike that I can't slow speed turn on without having toe overlap (usually this means I have fenders, but my road bikes also). I have size 12 feet and I like long cranks. For me it is just a fact of life.

The winning reply. thanks. Now I can really​ rest easier.

ThermionicScott 09-06-13 03:12 PM

No problem. That you had also changed cranks was the crucial clue. :thumb:

I am right there with you.. 11 and 11.5.. It could be just the characteristic of this bike..

Why would Giant have named a mountain bike BUTTE?

Who'd want to utter, "I have a Giant Butte."
