Taping 35mm dia bars

[AlanW]

I'm looking to purchase a pair of the Deda oversize bars, but I was wondering about the length of bar tape required?

I'm assuming that with the increase in the overall diameter you would require a longer length bar tape if you wanted the tape to finish in the "normal" place? I don't really want to finish the tape short because I spend a lot of time on the tops and I'm fearful that without tape I would be prone to road vibration problems, made even with the stiffer bars!

IIRC one roll is enough for one side of the longest/thickest bars out there and then you cut down if using smaller bars, as none of them seem to offer different length rolls.

That does surprise me TBH, because from my own experience wrapping bar tape, I would have thought that most tapes would come up short, guess it just it all depends on the amount of over lap?

I suppose if I could be bothered (or cleaver enough more the truth) I could mathematically calculate how much more tape would be required to cover 35mm diameter bars vs 31.8 mm diameter bars, assuming that you wanted to stop the tape say 75mm from each side of the stem.

Obviously you would do it for the various widths of bars too.

You should have enough. Remember to wrap from the inside to out on the drop section(clockwise looking from the saddle) and the opposite direction on the tops.

Your fear is justified. I always ran short when taping those wing bars.

Syncros bar tape seems to be quite generous in length ime

"Deda present the M35 concept in an alloy bar format. M35 bars have an oversized 35mm clamp diameter to deliver increased rigidity for more efficient power transfer compared to standard bars."
I think these bars are only 35mm in the clamping area (and taper 75mm (say) either side) so the diameter of the parts you'll be taping are no different in diameter. These bars are not 'wing' (cross-section) bars.
So no change to the tape length required.

Sorry, but you are incorrect, they are 35mm all the way across till the bar starts to curve.

This is what I suspected, so before I start I just needed to ask the question. Surely someone else must have purchased these bars? I must admit that after looking at the above photo, it suggests to me that prehaps they dont think that you should apply tape as far as one normally would?

No mention of alloy or carbon in your OP.

Always worth thinking carefully before calling someone out. The alloy M35 bars taper - so what I said was not "incorrect" - the text I quoted, with link, made it crystal clear that I referred to the alloy M35 bars - as @Vantage has cryptically pointed out ^^^.
The carbon bars carry the 35mm all the way across (about 150mm from the centre) so you'd only be taping the additional thickness for 75mm. I note from the BikeRadar review: "some will bemoan the fact that you can’t tape the top section".

I suppose if I could be bothered (or cleaver enough more the truth) I could mathematically calculate how much more tape would be required to cover 35mm diameter bars vs 31.8 mm diameter bars, assuming that you wanted to stop the tape say 75mm from each side of the stem

Whilst I was initially loath to pander to someone who can't be bothered and cloaks that in the veneer of lack of cleverness, here goes on the maths. Tape is 25mm wide and a 'normal' overlap is 10mm, so each turn of the tape covers 15mm of bar length. So for the M35 carbon bars the 75mm wider diameter length of the 35mm OD bar (cf 31.8) will be managed by 5 turns. Difference in circumference is Pi(35-31.8) = 10mm so for 5 turns you'll need 50mm longer tape. This represents one half turn of tape. I think you'll manage. HTH

I was actually thinking that other than a computer, who on earth would notice their bar being stiffer due to a slight increase in diameter and how much of a difference in performance it would actually make.

 

[Ajax Bay]

Vertically compliant but laterally stiff!

Well there you go, you learn something everyday, I honestly thought that all the Deda 35mm bars were in fact 35mm diameter across the whole length of the top. It was pure coincidence that I just happened to pick a random picture from a search that were carbon ones.

So I therefore owe you an apology, and many thanks for maths calculations.
