Xmcarbonspeed CS-R01 build

[Daviddavieboy]

Btw, has anyone any instructions for putting together one of these internally routed headsets, first time doing one and unsure what goes where

  Quite easy to figure out. Bearings top and bottom, C-ring then top cap. Sometimes if the top cap touches the frame a shim is needed or sand down the top cap but my R01 is perfect (no paint).

  For the hoses I route the hoses in the frame, through the bar-connect the bar, connect the levers and then mount the levers to the bar. On the other ends I try to push extra hose into the frame just in case at a later date I need to rebuild. (sometimes a few mm of hose needs to be trimmed off). If you do this use foam around internal hoses  so the do not rattle.

Thank you, all the additional spacers confused me but I can see it's essentially the same system as normal just with a cutout for cables. I'm lucky enough I just have to route the brake hoses but I'll put some foam around the rear brake hose which should help.

Just did a rough weigh on the built frame, seatpost, wheels, bar, headset, rotors and cassette and it's coming in at around 3100g, so hoping to get close to the 7kg with this

I don’t want to hijack this thread but, I just finished my build.  Rode about 80mi in the past 3 days.  Initial impressions, very satisfied, very pleased.  Overall experience dealing with Peter was excellent, I highly recommend.  Full disclosure, this was my very first time purchasing a frame direct from China (not my first chinese frame).  I will definitely do it again.

The CS-R01 ticks a lot of boxes for me.  MTF if the OP doesn’t mind.

@Icyseanfitz, I'am wainting for more photos of full build

You can definitely get it down to 7kg.  My full build with bar tape, pedals, bottle cages, front and rear computer mounts comes in 16lb/7.2kg.

Could you post pictures?

I’ll try to get some glamour shots this weekend.  Riding it everday.

Just waiting on tyre's to be delivered and I'll have it together, so far I'm happy with how it's turning out

Out of interest, what have you cycled before and how does the ride feel/quality compare for you?

[biceryder]

That’s a great question and a very subjective one.

Bikes I have spent a good amount of miles/kms on:

- 2012 Argon 18 Gallium Pro size 54cm (rim brake)
- 2019 Argon 18 Nitrogen size 54cm (disc/Di2)
- 2021 Giant TCR SL size Small (disc/AXS)
- 2021 Elves Falath Pro size 52cm (disc/Di2)
- 2009-10 Specialized Tarmac size 52cm (rim brake/Wheeltop)

Initially, I started out riding bikes that fit, but were too big once I started training more seriously and working towards a more aggressive aero position.

The TCR is probably the nicest bike I have owned but it
always felt slow compared to the Elves, even with Winspace Hypers on it. I should have actually been on an XS, as Giant’s Small size is bigger than I like.  When I got the Elves I put 4000mi on it in 4 months.  Zero issues. Sizing down and figuring out my reach and stack made a huge difference with my riding.

It really comes down to two things:

- I had knee surgery spring 24’ and was also diagnosed with a herniated lumbar disc fall 24’ (both completely unrelated to cycling). Getting low on the bike for more than an hour was starting to cause me pain that I could no longer tolerate.  I searched for a frame that had a shorter reach and taller stack than the Falath. The CS-R01 has solved this issue for me in terms of comfort. I haven’t been riding for the last two months due to my work schedule.  My second ride on the new frame was 2hrs.  Zero pain or fit issues.

- I have mostly been riding 25mm tires (at 79psi) on 19mm internal width wheels.  I tried 28s a few times and really could feel a difference. For the CS-R01 I got 24mm internal width wheels.  Running 28mm in the front and 30mm in the rear.  Both are run at 59psi with latex tubes.  Total game changer as far as ride feel goes. 

With only 100mi on the CS-R01, it feels more stable at high speeds. The CS-R01 “feels” stiffer than the Falath and I have put some good sprints down on that frame. It’s been cold and windy all week, during 3 of my test rides I had some very strong headwinds and crosswinds. The bike and wheels handled all these conditions better than any of my previous bikes.  All I can tell you is I feel better after riding for 2 hrs than I ever have on any of my previous bikes.

I apologize if I didn’t answer your question.  For me this frame was about alleviating a fit issue, due to physiological/health issues.  I still want to train hard and ride fast for the next 15-20yrs.

Wow great answer, thank you very much, interesting that initially you find it comparable to more expensive frames, with regards sizing down, it's something I've done for this actually, normally I'd ride a 56 but went with the 54 as that was the largest available and easily adjusted for with a longer stem etc.

my experience is mainly in mountain bikes so I'll find it harder to compare but Ive ridden a few different road bikes over the years, currently on a velobuild 086 rim, before that I had a CAAD 10 rim which I loved, also worked on some spendy bikes as a mechanic.

Really looking forward to testing this bike out.

[biceryder]

I will work on getting some pics up tomorrow.  I think you’ll be pleased.  Spending 12-14hrs a week on a bike really helps you get a feel for what works and what doesn’t.

My build as it is currently being ridden.

Build details:

Frame: CS-R01
Groupset: Dura-Ace Di2 11spd (previous gen before 12spd)
Cassette: DA 11-28
Crankset: Lexon 24mm with Ryet 50/34 chainrings
Saddle: Ryet carbon budget saddle (fits better than a 300.00 Selle)
Cockpit: Ryet Vero 36cm 100mm
Wheelset: Go-Zone 24mm IW, 30mm EW, 50mm deep
Tires: Pirelli P-Zeros (28mm front wheel, matching wheel profile. 30mm rear)
Latex tubes
Pedals: Favero Assimos

2 issues I encountered in my build:

1) Insert for fork thru axle popped out during a disassembly.  I used Gorilla Glue to fix this issue.

2) Rear exit port for Di2 RD cable was blocked by some
carbon excess.  I took my time, pushed different routing cables thru. Tested both directions trying to fish the cable.  Nothing worked.  About 1.5hr of head scratching and filing very carefully with a needle file I threw in the towel.  Grabbed my drillset, checked multiple times and looked at my angle of insertion. A quick, very light (I mean light) spin, blockage removed, Di2 cable through. Just a heads up.

PS: Routing fully wired Di2 is not something I will do again.  Cockpit, frame, etc.  All too much.  It took me two days to get everything together.  Wheeltop, wireless, 1hr.  Ltwoo ER9, 1.5hrs, brakes bled, bike tuned and ridden to bed in brakes.  Looking forward to Magene’s groupset release as a possible alternative in a year.

No pedantic weights.  I don’t care that much.  This was a budget build.  How good of a bike could I get for the lowest price.  Full disc, fully wired, pedals, both mounts and cages = 16.1lbs/7.27kgs.  Consider me pleased.  With a lighter cassette, cockpit, crank, chainrings, I could go lower but I’ll wait until my next build in another 2-3yrs.  Total cost sans groupset carried over from another bike, 16-1800USD. Besides wheels and frame a lot of my expenses were wrapped up in consumables and finishing kit.

**Disclaimer** Yes, there is a huge ugly stack of spacers under my steerer tube.  In addition to the huge head tube of the CS-R01, I still require spacers to ride without pain.  I’m disgusted at myself everyday… getting old sucks.

Looks amazing man
