Losing weight on Tern Verge P10

HI guys, I am new to this forum. I just acauired a new folding bike - the Tern Verge P10 and I would like to lose some weight (the bike's ofcourse) and would like some advice. My first target is the cranks. Is it worth the cost to weight? or any other issues? Can anyone share anything on this? Thanks.

I have never been a fan of the Vero crank. They are functional but heavy, so yes that would be the first thing I would change. I would also replace the bottom bracket with a lighter one. If it is square taper a White Industries might be a better choice. Other than that any other part change is going to be so minute or with compromise. Change out the saddle, go with a carbon seat post, might take some weight off. I would also look at the tires. I don't know about the Durano weight so they may be the lightest, I just don't know.

With enough money, you can make any bike lighter but there is a cost to benefit to ratio to consider. Good luck.

It's already a pretty nice bike. IMO the cost to weight savings ratio is only worth it if you're really into spending crazy money for the fun of it. I'd change the grips and saddle to stuff I like and just ride it.

If you want to shave some grams off your bike, the best way is first fully disassemble the bike down to frame, scale every parts, and make a big spreadsheet.
Then you can *simulate* the outcome of switching components, and calculate how much gram is shaved per dollars spent, etc.

But in general it is fairly hard to shave grams from Dahon/Tern bikes, as they are already equipped with very nice components (unlike Brompton).

Swapping steel bolts for Titanium ones will be an efficient wallet lightener too..

carbon or Ti seat mast.. ? (ones for Brompton's after market are .. 31.75mm (1.25") )

You have to measure yours..

What generation of P10 is it? Is it the current version with 451 wheels and disc brakes?

Regardless, one quick and dirty way to shave some weight would be to replace the bulky Tern seatpost with one of these:


Litepro Seatpost

For about $20 ish you could probably cut about 1/4 lb.

I have this type of seatpost on all of my folders and I really like them.

I doubt swapping out the crankset will result in much of a weight saving.

Also, I’m pretty sure there is only one iteration of the P10, and it has 451 wheels and disk brakes. It also has a very light seatpost.

Tern Strut seatpost - 442 grams, 105kg weight limit

Litepro seatpost - 388 grams, 80kg weight limit

Switching to a Litepro seatpost will net you a weight reduction of just 54 grams and a downgrade from 105kg to 80kg weight limit.

The Porter+ saddle on the P10, however, is heavy. It weights 404 grams. Could easily replace that for a saddle about 150 to 200 grams lighter.

The sidestand also weights about 250 grams. Removing that is an easy way to lose weight if it isn't needed.

Other than that, as the poster above mentioned, the components are already good quality and there's not much else that would make much of a difference without spending up big, and I agree that the OP is better off just using the bike as is.

That seems rather incredible/amazing, quite frankly.

I don't even know how that's possible. It would take a LOT of work for me bend one of these, and I weigh considerably more than you and I usually ride with a ~20 kg pack.

Out of curiosity, what kind of bike did you use them on and how far were they extended? Also, what kind of riding were you doing?

Such things cannot happen unless you violate the minimum insertion length. I have seen much heavier people using them with no issues.

My friend, dont get me wrong. when i receive those seatposts i think theu are a engenering marvelous, but thry archieve thatg point of lightness making it mutch weaker.
its surely aimed for asian market were people is more light/petit
we uses our litepro superlight on a dahon dove and on a dahon curve.
on dove it gets inside till 3 marking on seatpost.
on curve it gets inside till 4 marking on seatpost.
we usualy did commuter rides(30km) on flat terrain(mostly bikepath).
​​​​​​we ended up buying anothe litepro seatpost, mutch more roboust.
my adi
​​​​​vice on this matter is: dont buy those superlight seatposts unless you are a superlight rider

I found various different weights with some googling. Mostly around the 380 - 390 gram range. Are the different seatpost variations?

i really doubt that.
those seatposts are rated 75kg max.
so, its impossible much heavier people using then.
pehaps we are talking about diferent seatposts?
im talking about litepro superlight, rqted for 75kg max, with 600mm
