cycling pants is good enough for duathlon. not so sure about triathlon but I did swim a few laps in cycling bibs and doesn't feel any discomfort

urghh.....

I just had my first ever longer ride on trainer with Zwift

DNF Alpe du Zwift

Too much for me as stop cycling too long

Try put car LED strips, DIY RM$20 solution; extra bright, waterproof some more and superlightweight and blend nicely with any bike frame without looking obvious during day light. I ride every night daily for commuting. 5 hours lighting stamina. Save money than buying Cateyes.

My DIY lightings:

Nice!

Thx for the suggestion and interesting setup... seen you posting this some months back.

I'm already having my Lezyne front and rear lights for my weekday night cycling... I haven't riden more than 2hrs at night on my current setup so just worry the batteries dun last the whole LEKAS event. But anyway, was told it's luminated all the way, so no worries for me. Cheers

btw if u decide to buy this light, please use steady night mode if u use it for night ride with frens. the flash mode is really really bright. sked ur frends will tampar u

I had this funny moment at traffic light in the evening where some mat motor passes by pointed out at my bike that my DIY LED light strips are much brighter than hilux and vios who also had the same LED lights (SMD 5050 type) next to me. That driver had that funny look at their face thinking why that bicycle had better lightings despite using same LEDs and even confuse how did i power it, lol. Thanks to mat motor for giving a thumbs up.

Can you share how you do this LED setup on your bike?

hi everyone, i wan to order a merida scultura 400. but im not sure should i get S(50) or XS(47) frame size.

my height is 170cm, inseam 73cm, wingspan 165cm, shoulder 44cm

the shop i went dun have the XS size bike for me to test. anyone here got XS bike that are willing to let me test awhile? can treat u yamcha

Have you tried Pedalspot as they are one of the Merida retailers? They took measurements from me to see what frame size suited me.

ooh, i later go c.

170cm, u need a 44cm

r u serious?

why not. it all depends on bike geometry

I dunno how to relate but here's the geometry from Merida's website including a link to their frame calculator. Do note even with the frame calculator saying I need size 53, I had the shop did mine and got a size 50 frame.

wow.... inseam 73, and -5cm ape index, thats a tough bike geometry

seem like u got pretty short leggy and short hand with long body

advise is look at the bike chart for your height and get 1 size smaller

*edit, but i would agree also if someone with XS frame bike could go yamcha with him and test it out. at least he can refer to the XS bike brand geometry and compare to this scultura to estimate the size needed.

i highly doubt the S size would fit his inseam height. XS or maybe XXS is suited, but the XXS also is bad as the headtube stack height is too low for his short arm. XS it is!

what is

ape index?

body height vs wingspan. resulting your ape index, decide what kind of body you are.

positive ape index are good for bike fitter as they can easily accustom to any reach and stack (wider range)

compare to negative ape index ppl are limited to stack and reach (narrow range)
