Is the 3 bolt computer mount for the hbr17 handlebar proprietary ? Are there any other 3rd party solutions or can i adapt somehow a 2 bolt mount if the basic plastic one breaks?

A while ago I posted my workaround for using a generic 2-bolt adapter: https://chinertown.com/index.php/topic,5970.msg103168.html#msg103168

This is hacky, but it has worked for me without any problems.

Hi, I've searched the thread, but I haven't found anyone who had the same issue before, so here we go:

I have been a user of the WheelTop EDS TX for about 1.5 years now (probably ~10k km), but a few days ago I noticed that the shifting in the rear has become completely unreliable. Sometimes it skips gears, sometimes it doesn't shift at all. I did not change anything on the bike lately, so this definitely surprised me.

First thing I noticed was that one of the springs in the rear derailleur is broken, so I took it out, shortened it and bent it so it exerts tension on the housing again. I don't know how long has the spring been broken for, and I am not sure it caused the problem in the first place, but it certainly seems like it didn't resolve it. Next thing I figured out was that I can adjust the initial offset in the 12th gear all I want, but after a few shifts up and down, the derailleur is stuck in the 11th gear again. I can readjust the initial position indefinitely, but after some shifting it stops going into the smallest cog -- if only by a little bit every time. It is a weird issue and I am wondering if there is something else that I should check.

So, concrete questions I have:
- is there an option to factory reset the groupset? I can't find it in the app or on the internet.
- do you think I need a new rear derailleur?
- is new WheelTop hardware still compatible with the one from the ~2 years ago? Will a new rear derailleur work with other parts remaining the same?
- does it even make sense to buy the rear derailleur only? It costs ~325€ (270€ before taxes) before applying coupons on AliExpress. What are other sensible options?

I am also attaching a video of another potential issue I noticed. It doesn't explain the problem I described above, but I am wondering if your rear derailleurs exhibit the same play as in the video.

Any other ideas also welcome & thank you very much.

If you don't need the absolute lightest, but still competitive (in terms of weight) wheelset, I think Serenade is a great option that is cheaper or very similarly priced than other offerings around here. I got a 45mm carbon wheelset with carbon spokes from them this winter for 560€ including shipping to Europe. The wheelset weighs 1120g with tape installed (comes in the box).

The wheels I received were not *completely* balanced, but they were good enough so I was not bothered adjusting them. This is about the only complaint I have. The pros really outweigh the cons though: wheels are fast, don't feel sluggish, have maintained their balance during the ~4000km of use (this includes some unforgiving gravel use -- even though they are road bike wheels), the support has been great regarding some questions I had before and after ordering/using the wheelset. There seem to be a lot of good wheel manufacturer options available lately, but I can fully recommend Serenade. I think they shine especially in the pricing and aftersales support department.

That said, iGPSport's BSC500 lists very similar specs at a lower price, though I haven't delved into reviews for that one so I don't know whether it delivers. Would definitely investigate if I was in your position though!

EDIT: Whoops, might have gone and ordered the BSC500, will report back (and then eventually sell the weaker one, I guess 😅)

I have also been thinking about Magene C706 vs. iGPSport BSC500. I currently own the iGPSport BSC300T, and I have to say that the Magene's software experience seems much smoother, including less lagging, Strava segments, and generally more features. Now, I know that the BSC500 is a completely different device (arguably the same as BiNavi Air), and I am very interested to hear how the two compare.

Btw, I am also wondering what the resale value of Chinese bike computers is. Are they impossible to sell similarly to Chinese bikes?

Ugh, wish I waited for a bit longer. I hope they are not as bad as you say, but I will see, I guess.

Hi, does anyone have any experience with the KEMALOCE bibs. I am thinking of buying this one: https://www.aliexpress.com/item/1005005225331271.html. I am especially curious about the padding material.

Done only few rides with this but it's my new favorite saddle. Works very well in a aero position when rolling the pelvis forward. I have the 3D printed version very comfortable, it's not the cheese grater style like on Ryet saddles.

I also have this saddle and is the best saddle I have ever owned. I have the EVA version, and it offers great support and grip, and for the weight it is very well cushioned.

Hi,

I have been riding my SP-R088 for a while now and I have been really happy so far. However, recently the frame has developed a creaking noise while I pedal at high (300+ W) power. Really annoying when going uphill. I have retightened the crank (actually, I got a new crank arm, but that is another story), so my next suspect is the bottom bracket. I tried to tighten it already, but it doesn't move any more.

Any ideas how I should go about this? Should I add more grease or something? Any other suggestions on what I should check? I am pretty sure the creaking is coming from the drivetrain area. I distinctly remember creaking when I push down with my right leg, and I am not entirely sure whether it is also present on the opposite side.
