Now I'm confused. It seems like you're talking about moving your saddle relative to the BB, rather than just changing to a seatpost with less setback in the cradle while keeping the same saddle-BB offset.

"Bar Tape" ?

I should have been more specific. What I had meant above was that the saddle fore/aft position relative to the saddle rail clamp of the seat post should be set for balance, whereas the seat post offset should be used to adjust reach.
For example, if the saddle rails are clamped toward the rear of their useable range, then a rider sitting on the middle of the saddle would tend fall forward and put too much weight on his/her hands (as you had described). It may be better to get a zero offset seat post and clamp the saddle rails at (or slightly forward of) the middle of their useable range to adjust the balance while maintaining the saddle fore/aft position relative to the bike frame. |

"Set for balance"? What? and "seat post offset should used to adjust reach"? No. Not how it's done.

Okay, so let me start by admitting I've never changed my bar tape before. Seemed easy enough. Bought some tape, watched a couple vids. And, dammit... Did I wrap too tight or are there different lengths of bar tape? Because I came up a few inches short. (insert joke)

Perhaps I have misunderstood what the two videos I linked are describing. So how should saddle fore/aft position be set?
I have a variety of bikes with different seat tube angles, from fairly steep to fairly slack. The slackest ones, I use zero setback posts with the saddle clamped near the back of the rails, whereas on the steepest I have a seatpost with 2cm of setback clamped in the middle of the rails. But they all have the same setback relative to the bottom bracket. |
Hypothetically the saddle and post flex a different way with different seat tube angles and seatpost offsets but same saddle setback from BB. How much of an issue it is in practice? I can't really feel it 🤷

Supacaz is a great tape, but it's on the short side. Doesn't leave a lot of margin for error. Glad you got it sorted.

practice my son....

There isn't a right or wrong way per se, but the preferred way is, when viewing the bars from above, to be moving away for the frame when you come over with the wrap, starting at the drops. That way, as your hands naturally "rev" on the handle bars, it goes in the direction of the tape.
And some tapes are naturally shorter. I used Deda tape on my bike originally, and had no choice but to overlap only a third or I'd never make it to the top, and even then it didn't come as far up as I prefer. I used Cicelli tape last time, and could've overlapped by half and would still have tape left over. |

That's the direction I wrap, and was taught to wrap.

Starting at the bar end:
I hate when the bar end tape starts getting loose. Grrr. Here's how I start the taping: I use a narrow strip of gorilla tape to secure the end of the tape to the bar end. It's half on the bar, half for folding over inside the plug. This is way more secure than using electrical tape. The tape end is on the bottom of the bar. One full revolution around the bar end, no angling yet. Now I start angling up the bar, overlapping about 1/3 of the tape. Pull it pretty tight here. ~~~ I like tapes without the adhesive strips -- silicone grippers are way easier. I often have to redo the part past the shifters to get good coverage at the turn -- lots of overlap there, and still reach the middle of the bar area. Tapes are shorter than they used to be! |

Agree with no adhesive. Not only does it gunk up the bar (I know it's hidden, but still), but it also makes it difficult to unwind a little to make adjustments or fix a mistake. I can get picky and want both sides to have the same thickness and number of turns. |

Cinelli tape, OTOH - the adhesive is too strong and the tape itself too weak, so that if you're trying to adjust the wrap any time down the road, the adhesive tears up the tape. Luckily Cinelli tape is cheap - I use it for the first wrap after a build, so that if I later decide I need a different bar or stem, I'm not out the cost of good tape. |

Sorry to have sidetracked with the saddle position vs. seat post offset discussion. Back to the main topic, here is my OCD way of wrapping bar tape:
Start from bar end, leaving an overhang of about half the width of the bar tape for securing bar end plugs, wrap outward (i.e., clockwise when looking at right bar end from rear and anti-clockwise when looking at left bar end from rear), overlapping by about 1/3 on the bottom (i.e., outside of curve of bar shape), because the extent of overlap on the top (i.e., insider of curve of bar shape) would change as bar curves, swap tape direction around base of STI lever, so that the tops are wrapped by pulling tape over the top toward rear of bike. Do not cut, temporarily tape bar tape in place with masking tape, then do the other side. Both sides should end with same remaining lengths; if not, redo the side with longer remainder, using slightly less tension, until both sides have same remaining lengths. Then cut and secure with finishing tape. |

I like the adhesive, because I'm forever misplacing the electrical tape or the shears I use to cut the angled end up by the stem, and I have to step away and find them, and when I come back, with the adhesive I only have to redo the last loop.
I also seem to remember starting at the stem and finishing down by the bar ends. If there were mistakes to be made - I made them! |

LOL I am reminded of the slippery plastic tape my old (70s-era) Sears bike had..... It wasn't stretchy or clingy at all so you had to keep it wound tightly the whole time until you could tape down the ends. Letting go for just a moment would cause a dozen or more loops to immediately uncoil!

Some folks do wrap from stem to bar ends. Then you don't need finishing tape. I've never done that, myself.
Next time I do a wrap job, I think I'll give it a try. |

I'm stuck in my habits, but I don't know why starting at the stem isn't more popular. I can't see it not resulting in an equal product; you're wrapping the same, just backwards. Most tapes offer more than enough that you don't need to worry about running out.
Next time I do a wrap job, I think I'll give it a try. Sometimes things are done the way they are done because that's the way they are done, and justifications are imagined and argued. Wrap your tape how you like. Buck convention. Live free or die. |
