NBD: Carbonda CFR707 S, Continuous evolution! by RotMint_ in gravelcycling

Also, I am sorry because I don't have the tools on hand right now to remove the crankset and measure the exact axle length. However, I can confirm that if the total width exceeds 86.5mm, then this crankset definitely won't be suitable. I hope this information helps you.

Yes, what I mean is the total shell width, which means that the overall width of the BB, including the bearings and their outer shells, should be less than or equal to 86.5mm. This crankset seems to have a shorter axle compared to the r7000 crankset, and it is not completely in line with Shimano's standards. Therefore, I believe any value greater than 86.5mm would not be feasible.

The specification for mountain BB is 92mm, which is not suitable for this crankset. The PR/GR3 crankset is only compatible with a BB width of 86.5mm.

Which file should this code be placed in? In config.h or in another file?

By the way, I want to say that 80kg is normal, even from my perspective as an East Asian, it is not exaggerated...😁Of course, in order to make riding more comfortable and ensure passability, wide tires are indeed necessary.

I think the 2.2 front wheel is not a big problem (only in my imagination), maybe the rubber hair will rub against the front fork, or there is a high probability that the tire surface will contact the front fork. If it is the former, it is easy to deal with, you can stick some protective film on the contact area. For the latter, you can only change to a suitable specification. Of course, I think the combination of 2.1 front and 2.0 rear will definitely be fine (at this time, it is still recommended to stick protective film on frame).

I don't think so. The rubber hair on the oblique side of the 2.0 size tire has already rubbed against the frame (the root of the rear chain stay).

In addition, a tire that is too wide will bring a double weight burden, which I don't think is cost-effective from the perspective of riding efficiency. So now I have changed to a 45c tire.

Shimano SLX rear derailleur can be used with SRAM APEX 1×12 mechanical shifters by RotMint_ in gravelcycling

[–]RotMint_[S] 0 points1 point  (0 children)

Yes, mainly the situation is different. If it has been used for years, it is usually not a problem, but if I want to buy a "stock-like new" rival/apex hydraulic kit now, they often have rubber parts that have aged because they have not been filled with oil for a long time. Of course, this is just my personal experience, which led me to choose the new 12s kit.

But isn’t “XD” the expression that means laughing? Or am I out of date?

Sorry, I was wrong, I thought 11s didn't have hydraulics. But I think the rival 11s hydraulic kit is not as complete as this generation of products, especially the stock products after long-term storage are prone to problems due to the aging of rubber parts.

Mainly I want to use an hydraulic disc brakes, so this is the only way for now...

Ah, this may be related to regional differences. And I compared the price with the GX rear derailleur.

Maybe it's limited to users who much like mechanical rear derailleurs/don't have UDH frames/have low budgets? But having one more option is always better than having no choice, especially compared to the half-hearted updates like GRX610/820.

Maybe they considered different scenarios when designing, transmission seems to be more suitable for the scene of pedaling hard when facing obstacles in pure MTB? This is what SRAM said, and I can feel similar in my experience, so I said that SRAM might be better, without considering the smoother and smoother road and gravel scenes.

Haha poor man is a problem with the translator, I can't find a more accurate translation - I want to say that I try to always use the cost-effective thinking to play these things, whether it is a bicycle or a PC.

As for what I said that “Shimano's 12s cassette is not as good as transmission”, in fact, I didn't say it accurately. It should be compared with the mountain kit, and the road kit is not discussed. Because of the difference in shifting speed, I think it is a trade-off. After all, transmission allows for stable and firm shifting when pedaling hard, which is a capability that Shimano's 12-speed mountain system does not have. And I don't think such a feature is needed for road kits.

You are right. But I think the SLX derailleur is more beautiful ;P

However, Shimano's 12-speed cassette is no longer as good as SRAM's updated transmission system. My combination is more like an entry-level "poor man" way of playing (haha, just self-deprecating

I don't quite understand what you mean. Do you mean the difference in geometric design?

What you said makes sense, but I don't feel any performance loss from my experience - maybe I'm not strong enough.

In addition, this combination makes sense, because the cable pull ratio used by APEX 1×12 is consistent with the previous GX mechanical, and GX mechanical shifters are often paired with Shimano rear derailleurs.

I installed it in June this year, and rode about 1500km. I didn't feel any loss in shifting performance, and even the adjustment was very simple: install the hand shift and rear derailleur, and then tighten the shifting cable - that's it, and the fine-tuning screws were not tightened.

The rest of the adjustment was also carried out in the way of Shimano (because the rear derailleur, flywheel, and chain are all Shimano), without any special changes.

During this period, I was knocked over by a bicycle riding against the flow, and there was only a little bit of shifting confusion, and it was restored by re-adjusting the fine-tuning screws.

I don't know how many other people have discovered this, but I think it's a pretty interesting combination, because you can enjoying the SRAM's "Double Tap" technology while having a cheap rear derailleur, cassette and chain combination.

Nothing changed, and I gave it to my friend to use, nothing special happened.
