Re: Latest Tiagra mechs - use with r7000 shifters?

The rear shift ratio of 4700 is the same with 5800/6800/9000/7000/8000/9100, but different from 5700, which means you can use ST5800/7000 with RD4700 in a 11 speed system, but you can not use ST4700 to replace ST5700 which is also 10 speed.

Re: Bike light

$20 is too much for that simple light.
You can get a similar shaped light at $5 on aliexpress, or a better one with brake(accelerator) sensor (Xlite) at the same price.

Re: Do you think this new Ritchey carbon stem is genuine....?

It's a knock-off made in Xiamen or Dongguan, selling around just 15 gbp on taobao.
e.g, one with no logo.

Ritchey doesn't use these kind of crews shown on ebay.

Re: BMC Teammachine frame size 51cm or 54cm?

SLR02 51, S=530 R=378, crank=170, stem=100; 54 S=550 R=386, crank=172.5, stem=110, according to BMC website. I don't think a M size (54) raod bike should be equipped with 175 crank anyway. You can see the reach between 51 and 54 only changes 8mm, and maybe different number of spacers can bring more ...

Re: wheel and tyre upgrade advice

2011 is an old model, so take care of the tyre clearance, as a lot of old road bike only support 23c tyre. Moreover, a lot of 25c tyres will measure 27~28mm @ 90psi on a 17c wheel, which could bring the same clearance problem. For the riding quality, I would suggest conti GP5000 / GP5000TL (if your ...

Re: Why didn't this seal & can I fix it or new tyre?

Your sealent seems becoming too weak as you have already ridden on it for six months. I usually add/change the sealent around per 3~5 months (-5C in winter & 35C in summer). When the sealent can not do its job, I always try the inner tube patch, like: https://www.wiggle.com/lifeline-puncture-rep...

You are right. If you keep the same saddle position and the same stem, size L is more relax.

The fitter will measure and test your body function first, and then you will pedaling on the simulation bike and adjust everything. The whole process can take 3~4 ho...

Re: Road tubeless tyres, where and how much?

A blister? I will change it. Pro one's are good tyres. They are fast, relatively easy to mount and inflat. The weakness is mileage and puncture resistance. For a summer bike it's a good option. GP5000 TL's are faster, longer mileage and easier to inflat, but hard to mount. Thanks alan. I was lookin...

Re: Road tubeless tyres, where and how much?

Okay. I'm on the tubeless but only because when I bought the wheelset I didn't realise they were tubeless. The wheels Mavic Ksyrium Elites had the usual Mavic tyres on them. So I bunged in the sealant and inflated them and just rode them. Now, after just over 1500 miles there is a blister on the re...

Re: Jerseys with similar fit to Castelli Free Aero?

Sportful has a similar fit to Castelli (made in the same factory), while Rapha team's have a even more slender fit.
(XS size of castelli is still a little larger for me but that of rapha team fits me quite well)

1, Yes, it's a true carbon wheel. 2, Yes, you can use clincher and tube on any UST/TLR/Tubeless wheels. Cosmic Pro UST wheelset will come with tubeless tyres. My suggestion is to use the tubeless first and you won't be disapointed by the comfort introduced by tubeless, unless the road is so bad wher...

Re: Carbon cage for Camelbak Podium

Chinese / cheap copy (whatever you call) XXX bottle cage on aliexpress. 10 usd each, 18g.

I've used six Chinese XXX cages since my first bike. It holds my camelback podium well, not too tight. The quality is also good and only one was broken due to my kick.

Re: Tubeless virgins struggle

I've met with the same problem with a hand-built wheelset. The rear wheel is all Ok but the front one leaks at the valve. My solution is: one more layer tape, and use a electric soldering iron to "burn" a hole through the tape, which is smaller than the valve.

Re: SPDs on a road bike?

I used A530, R8000 and now Xpro 15 on my road bike.

For commuting, weekend riding, touring... A530 is perfect.
For racing, R8000 and Xpro 15 are better.

Re: Long gravel bikes and short stems

How much longer?
I have ridden on a long drop bar touring bike, but the bar is much higher than the road bike I'm riding now. Although the total reach from BB to hoods of the touring bike is ~10mm longer than that of my road bike, I feel more relaxed due to the higher bar.
