Mark B's S 40 Build

I finally got all the bits and pieces together to build my S 40. I ran into a few issues, though.

First and foremost, I got stuck on brakes. Discs are a new thing, to me, so I shouldn't wonder. I elected to go with TRP Spyre SLC. I opened the box to check it out and lo and behold, all that is in the box is the brake. No mounting hardware, nothing. That seemed a little weird. So, I start looking at how it's going to mount and It appears I need an IS adapter? Poop. Now I need not only bolts, but an adapter. I look on TRP's website and it appears there are many choices.

I thought I wanted to run 140 mm rotors, but I see the complete bikes come with 160. Can I run 140?

I will post pics of the build so far at a later point in time. I got the TFT set to where I want it and I can tell it's going to be comfy and fun. I still feel like I will be slamming the stem, but will wait a while.

Had good luck with wheels and tire combo. I went with Stans No Tube wheels and Maxis Padrones. I was able to put the tires on easily by hand and inflate them with my floor pump. That was a pleasant surprise!

Looking forward to the rest of the build.

I just want to say congrats on getting your build mostly done! Hopefully you can get the brakes sorted out before long!

I used trp sl 160 mm rotors with shimano 160 mm IS mounts both were rear mounts. That was on vendetta v2067AA793B-6D26-4D50-BDE9-60C0860BCA0F.jpeg


Personally I think 160 front 140 rear rotor size minimum would suffice. Guess it’s funds and what’s in the spares box. Hope that helps.

Interesting to hear what your thoughts will be on s40 as an experienced pilot.

I’m tipping a great experience and solid gains.

I'd prefer a 180 front, at least for me, but 160 is 'ok'.

160 has the dubious advantage of never being able to fully lock up my front wheel.

I wouldn’t recommend 140 discs on the S40 unless you weigh 125 lbs or so

Things I know and things I think I know. S40 edition. AKA Grumpy Curmudgeon edition.

My ride is complete!

This build fought me a lot more than some builds. Much of it was my own fault and I freely admit that. Still, it was a bit frustrating, at times. I was dealing with some new to me tech... Disc brakes, electric shifting, tubeless tires, and to my surprise. the thing that kicked me the hardest was the brakes. More later.

Things I learned.
The package arrived from Cruzbike well packed with no damage. The frame, under close inspection, is well built and the finish was more than adequate. My only comment is the welds are rather bulky looking, by today's standards. Look at modern hydroformed road bike frames and the welds are virtually invisible. In fact, you almost have to tink, tink, tink on the tubes to see if they are alloy, or carbon. Fortunately, I don't really care and yes, I know that my version 1.0 has the welds hidden with Bondo,

I tend to rush in to things and this was no different. When I ordered my brakes, (Spyre SLC) I was sure I needed flat mounts. Turned out, I needed post mounts. Then, I realized I needed adapters, even then. Thinking I was smart, I ordered a front mount and a rear mount, thinking the front mount would go on the rear and there rear mount would go on the front of our bikes. After I had placed my order, Jond correctly informed me I needed both rears. Who knew, but Jond? So, for now, I have a 140 on the rear of my bike and a 160 up front. That will change, soon. As for the setup, the SLCs were easy-peasy to set up. They gave me no issues, at all, once I had all the pieces parts I needed.

I built my bike around SRAM e-tap. I went with the mid compact 52-36 chainrings and the Wi-fli rear derailleur, so 11-32. Nice stuff! Setup was stupid easy. My only struggle is the little wedge that goes between the mounting stalk and the front derailleur. There isn't enough adjustment to reach, so I didn't put it on. It seems to shift just fine on the front without it. I did cut corners on the chain and the cassette, opting for the Force level gear and it seems to work just fine. The chain is hollow pin and you should know that with the Wi Fli, the S40 and all that, do not buy a standard 114 link chain. They offer the PG 1170 in both 114 and 120 link increments and the 114 is a full link too short. Buy the 120.

The S40 is a much bigger bike than the 1.0. I had to stretch my bike rack out to accommodate it and now, I can see wheel sticking out on either side of my car, from the side mirrors. I haven't measured, yet, but I'd say the wheelbase has stretched a good 4 inches.

The S40 sits up higher than the 1.0. Again, not measured, but I'd say a full inch, maybe two. I will gather more details on that in the near future. Here's a pic.
Being fair, the S40 is sitting on a stand and the 1.o is on the floor, so give back maybe an inch. Still, it is clearly higher.

Bottom bracket is now lower.
Maybe hard to tell from this angle, again, the S40 is sitting on a stand, so give back an inch, but given the difference in the seat height, it's a lower bottom bracket. Much lower and I felt it on the test ride. I felt slower, especially on the climb, but I know this is an acclimation thing. As is the width of the chain stays. I got some heel strike on the chain stays. I don't like that, but I will get used to it and accommodate for it in the future.

The seat is..... different. The nose of the seat is almost non existent and I thought I might have a feeling of wanting to slide off the front. So far, that hasn't been the case, but the jury is still out. The old Silvio seat gave you a feeling of sitting down in it, not on it. Maybe this will be better for recumbutt, we shall see. Then there is the water bottle bracket mounting issue. I still haven't sorted that out. Not to my satisfaction, anyway. I really don't want to bolt more stuff to the bike, at this point (ie, the headrest bottle mount adapter thingy). Speaking of which, to me, the headrest thingy is pretty much useless. I threw the pad in the corner. I did find that the frame for the headrest makes a good place to hang my seat bag and I will use it for mounting a tail light, at some point, so not completely useless. Otherwise, it just gets in my way throwing my leg over the seat back. Again, going back to the higher seat and then the head rest.... Much bigger challenge.

I weighed both bikes and the S40 comes in a full two pounds lighter than my 1.0. I was hoping for a little more difference than that, but given the longer wheelbase and higher seating position, I guess it's pretty good that way.

My initial test ride was ok. I didn't go but down the street and back, which means a good, fast downhill run, turn around and slog back up the hill. I didn't have a computer on the bike, so I have no idea how fast I was going in either direction, but the lower bottom bracket felt odd and everything was different. The heel strike was a little disconcerting and I am going to assure you the bottle will absolutely not be staying on the TFT. My legs hit is and NO, that will not work. Overall, once acclimated, I think it will be fine but....

This morning, I am sensing a little bit of buyers' remorse. Probably not as bad as the guy that buys a Cruzbike for the first time and realizes there is a learning curve. I can ride the bike, but I am not going to set the world on fire out of the chute. This is going to take a minute. I have all the time in the world and I am happy with a lot of the things, but I still have a little dialing in to do with water bottles, Garmin mounting, lights and such. No worries, I will get over it and in a couple weeks, absolutely be loving this bike. In the meantime, all I can do is ride!

There will be more I will add as I figure all this out.

Wow! Nice!
However I wish the S40 seat was as low as 520mm or atmost 550mm. But I guess they were considering clearance for the underseat panniers.

Right? Now, I wish I had maybe given a little harder look at a V. With the condition of our roads and craziness of our traffic, I was concerned about my vision. Also... I wear bifocals, so that sort of inclination does not mix well with them. OR, so I thought. Like I said, I think it will all work out and I will be happy with the S40. It's just different.

Nice looking build. Wondering what your final weight is with all the bags, pedals etc on board.
Also interested to hear how you like the sling bag under the seat. Looking at that as a possibility. If you are like me (6'1", 190 lbs) you may find that water bottle mount to be a problem. It's handy but I found I was always getting poked in the stomach and occasionally found myself banging my thigh on the cage during starts or unexpected stops. I went with an under seat cage mount that you can find on a bottle cage mount thread. Enjoy. It's a sweet ride!

Thanks! Yes, I'm 6' 190. Just my legs tough the bottle, but that, in turn can affect steering. In my mind, anyway. The bottle will go somewhere else. I looked at your underseat modification and I'm working on something like that. If worse comes to worse, I will do that short term, but I do not trust zip ties long term.

Mark,

I had to move the cages up further on the seat. I used the upper mount hole as the bottom and drilled a new upper mount hole. I then use 1" spacers to clear the frame.

In retrospect, I should have gone higher on the seat, since I initially had issues with the water bottles ejecting on any slight irregularities in the road. That is why there are bolts in the upper rack mount. Here are a couple pics.

Ditto on the zip ties. I have just replaced them with metal hose clamps which I wrapped in old Lizard Skin bar wrap where they contact the frame. Should be good for the long haul now.

I think your S40 is a good/better choice than the V for you. You just need time to adapt and fine tune your new position and I think it will be very fast and practical!

See if Cruzbike will sell you a longer chainstay. It will raise the BB and probably also help with the heel strike.

Hi mark. Great build great looker. Get that chainstay if you can afford to.

Have no expectations just ride her. She sure is a lovely orange.

Cool.
 

Mark B

Zen MBB Master
Yes, I got a longer chainstay for my Q45 no problem. They probably have them for all models. I just sent an email to support to get it.

Thank you for your reply, woodguy! I sent them an email yesterday, but haven't heard anything back. I will probably try shortening my TFT a little and in effect, raise my bottom bracket some. I haven't really even ridden the bike but maybe a mile, so I really need to just calm down and focus on the big stuff. Like bottle cages. Water is always a good thing to have on a ride!

One thing I learned this build on threading cable housing through the frame. I was struggling to get it done and finally fished some mechanics wire through first. I started at the head tube end and fed the wire through. A strong magnet at the mid frame exit hole brought the wire through like a charm. Then, I stuck the wire into the end of my cable housing as far as it would go and gently pushed/pulled the cable housing through. It took a little wiggling to feed the housing through the upper hole, but it went through pretty easily. For the record, I first tried this trick starting from the mid frame hole and feeding the wire toward the head tube end. The housing went through just fine, right up to the point where it got to the mid frame hole, where it hung up badly and I could not get it to wiggle through.

Anyway, kind of a silly little thing, but maybe it will save somebody some time.

I do something similar using a brake/shifter cable:
Run the cable through the frame, then feed the housing onto the cable. At the frame holes, the housing is easy to manipulate by pulling on the cable.
(I use a tandem length super long cable for this, mostly out of laziness.)

I haven't tried your strategy yet, but next time, I'll try that instead :)
