Xmcarbonspeed CS-R01 build

[Serge_K]

Yes they are tiny. Have you never disassembled one ?

Well then that's retarded! Why does DUB exist? Why does T47 exist? If neither allows for properly sized bearings?
All the bikes i built were using 24mm axles.

I have several bikes and the two DUB/T47 bikes are the only ones I have had issues with. I did have a creakingdale SuperSix with a BB30 but that was the Bb style not the bearings. The solution was a praxis thread together BB. I no longer have that bike tho.


I do have to say though since I put quality bearings in both (and sealed they with extra grease ) I no longer have any issues.

I wrote the wrong bike, not the wrong frame. He's on bad tyres (french sponsor), butyl tyres, large bars, wheels that aren't deep enough, and yes, a slow frame, that's not made for the flat, which means he loves his position out of the saddle climbing, but he's not comfortable in tuck, and so he catches more wind than he should.
And so, ride for 90min at 40kmh on the flat, add all of these "marginal" things together all at once, and it hurts. Idk how slow that frame tested on the tour magazine, but it can't have tested well.

That said, maybe i'm lying. Maybe i dont exist. Maybe i'm a russian bot. Maybe i'm a trad wife. Maybe sometimes i wish i were a trad wife.

Im also considering CS-R06 instead of CS-R01.

Could You post some drivetrain side photo of finished build?

Why one over the other ? just curious .

Not OP, but I am also leaning more towards the R06 than the R01 for two main reasons: racier geometry and I think it looks betters.

+1

I agree 100% with that.

The stack and reach seem to be same from what I see.  What am I missing?

One should look at how it is constructed and look for good aftermarket solutions. From what I know Sram use same tiny bearings regardless of BB shell to cut the costs, whether is T47->Dub or BB86->Dub. I got the issue when I bought shitty BB86->30mm axle BB which abruptly fall apart and destroyed the axle of my cranks. Then I bought Hope BB which is of another construction, has slightly larger bearings and lasted far longer. Yet again, it failed miserably and abruptly during the wet race and destroyed another crankset again

Moral of the story: big balls in BB = good, small balls in BB = bad.

It seems to depend on the size a bit: for example, in size M (515), the R01 has a stack/reach of 548/373.6, while the R06 has 548/379, so the reach is about  5.4mm longer on the R06.

The R06 also has a ~5mm longer effective top tube.

I think Bon Scott sang about this LOL

5mm is NOT going to make any difference.

Adding my own build to this thread for anyone interested:

Frame size is XS with wheels Elitewheels ENT and groupset Ltwoo erx v3.0. Just built the bike up about a week ago. This was my first time building a full build from scratch so bare that in mind. Build went well with two minor hiccups:

• The headset cover spacer was rubbing the frame when the preload was set so i had to add a couple of microspacers to the assembly as well as sanded down the top cover.
• The RD cable exit in the frame was too small so I had to sand it down just a little bit to get the cable through.

I still have a problem with the smallest gear (large cog with small front chainring) as it rubs the front derailleur cage with the limit set to its lowest. I have a couple of spacers on the way and will try fitting that and see how that goes. I had the seatpost slip on my first outing so i refitted it with extra grip paste and a little bit more torque and have had no problems since then.

Putting these little problems aside the bike rides like a dream. I currently have ~250km on it and have no complaints whatsoever. For context I am by no means a fast rider nor am i putting out huge amounts of watts and with that said, the bike feels fast and responsive. It might just be that for the first time I have a frame size that actually fits me, which is also partially why I went this route with my build. It is a little harsher on my cracked local roads than my previous gravel bike with road tires which is to be expected but it is by no means uncomfortable. I would say the opposite, I feel extremely comfortable on this bike. I ordered Peter's handlebar in size 380x90 and I am very happy I did as it is beautiful and comfortable for me.

Peter gets a lot of praise from the members of this forum and I will be joining these reviews, as he was quick to respond, gave me most of the information I asked for and provided very good feedback on my wishes, but mainly his product looks to be of really good quality, cannot say much more with only 250kms ridden. New wheelset sadly didn't fit into my budget for this build but in the future, Peter and XMCarbonspeed will most definitely be at the top of my list for ordering new build components.

I will try to snap some nicer photos of the build in the future.

Didn't realize. I guess I'll add this to the list of bad SRAM engineering decisions, along with hookless, 10T cog, small chainrings, FD that doesnt work, and more.

I consider myself fortunate that the nightmares others have had with front derailleurs. I have Force and a Rival AXS set up and they have been perfect. They are a bit of a pain to initially set up but all has been good. Also I kinda like the 10t cog as I can have a smaller big ring to help with the hills. I don't even get into the 10t until I hit 25 mph + on flats.  My days of turning big gears are LONG behind me - my knees cant take it LOL

First ride today, 66km, first impressions are rocketship, any bit of power I put in was was translated into speed, when I was up to 30kmh + bike held speed fantastically. Also found it to be quite comfortable although I might need to adjust fit a little.
Only issue I had was when heavy sprinting the front rotor was hitting the pads slightly, not a big issue and I might be able to adjust the caliper to correct it. Overall, love the bike

How its the handling descending with this frame? Its stable or not?. Can you give more feedback about your riding experience in general

Regards

[biceryder]

I finished my build in Jan and then made heavy modifications to the cockpit in Feb.  It's since become my daily training/travel bike.  On descents it seems to handle well for me.  I haven't taken it down any long, steep mountain switchbacks yet, but I did do a few short, twisty descents this weekend and I felt stable.

Beautiful! What color is that exactly?
