Klein Quantum Race/ Focus WW project

[ogu]

Hello everyone !

I'm 17 and i got back into cycling recently and i'd like to share my first build.

I bought a klein quantum race and built it with parts i had laying around, ultegra 6500 6700 and 6800, deda rhm, flite, ... It is quite heavy due to the wheels. I don't have a scale yet but i ordered one

This frame is a bit big for me so i bought a 2015 focus cayo 4.0 (damaged) in a size S :

- repair the frame, sand everything and clearcoat
- 11sp groupset
- tune speedneedle
- chinese seatpost
- clincher/tubeless wheelset (carbon)

I have some questions:

I found a cool campy record eps V1 groupset but i don't like the external battery nor the price of a new one. Is there a way to hack and take the "brain" of the V1 battery and connect it to an inline one in the frame? (i've seen it for di2 but not a for campagnolo)

I anybody has advices about the carbon repair. I have some UD tape, some High tg epoxy, shrink tape. I'm not sure how many layers i should do (for seatstays, chainstays). It is a challenge for me as i usually weld metal but never repaired composites

EDIT 11/2021 : the frame is repaired and custom painted but i dont want to ride it anymore ...


Thank you, have a nice day!

That klein frame is a beauty , if I were you I'd pass on the Focus and upgrade the Klein, those are great frames.

Hey guys !

Quick update, i repaired the focus and got a friend to custom it. I going to see what i do with it in a few months.

In the meantime i kept on riding the Klein quantum. I feel the more i ride the more i damage the nice paint job but ...



Klein Quantum Race frameset 54
Elita "chinese" seatpost
Kalloy stem
Ritchey evocurve
Flite titanium saddle
campagnolo levers/derailleurs
Ciamillo zero gravity brakes
ultegra crankset
zipp 404 on o lite 11 sp hubs
Vittoria corsa graphene 28's
Chinese links cables

I swapped the wheels for some ZIPP 404 clinchers with 11speed hubs. Got them for cheap so why not !

I also got a non working chorus 11 groupset. It was only dirty and now it working great on my bike.

The campag brakes were not clearing the 28s so i bought a pair of Zero Gs for 60€ !

I ordered a new 38 cm carbon handlebars to test the fit (and a nicer gps mount)

Also on the hunt for a speedneedle and a 50/34 and 170 mm campagnolo crankset (so hard to find used)

I also need to remove the graphics on the stem and clean up the cabling.

I love the bike! and it so much nicer with the new groupset.

I am abroad for a few months and i dont have any scale here but weightwise, its not light... i try to get there but these wheels are heaavy

I will get some nice pictures when its done !

Where you finding these deals man! +?? Great looking bike BTW

Nice! More than a few similarities to my Quantum with the Elita, Kalloy and Ciamillo's. I get your fear of damaging the paint whilst riding, but these bikes are so good I believe they deserved to be ridden and raced as much as you like! I'd rather make good memories with it:)
I'll try to write an update soon on mine, had a few changes on it and I think the build is coming to and end now.

How on earth do you get 28's in there? My 23's seem to be a tight and close fit, I fear 25 will destroy the forks and stays.

Love the Quantum. Too bad it's a tad to big... I lost hope finding a mint Quantum in my size (which is around 50cm). The majority out there is like 55 and bigger.

Love the bike! Crazy you got those Ciamillos so cheap.

I have a Cenatur carbon compact chainset if you're still looking?

[DHG01]

Very nice looking bike and great age to get back to cycling!

The handlebars seem pretty long reach. Perhaps shorter reach would help with sizing?

It's been a while since i checked the forum!


@stanvr the rims are pretty narrow so i think they fit smaller than 28cm.

A few months ago, i swapped the saddle for a speedneedle and i got some 38 cm wide bars (shorter reach). I also fitted a 3D+/Srm crankset in 50/36 for the steep climbs i had back in italy. I really love this bike in the end with these modifications.

I really disliked the fabric bottle cages in the long run, i kept on losing bottles so i bought some arundel mandibles and they work so well compared to the fabric.

For my fit problem, the reach is still too big even with a short stem, no seatpost setback and a 'short reach' handlebars. If i shorten everything even more the handling will be weird i guess.

To do list :
- get a bikefit
- change the leather on the speedneedle
- new bartape/new hoods
- crankset overall (battery/de-anodizing the some of the red stuff), going 1x (it is so flat where i live now)

In the end i may sell it for something more modern and fitting (i'm thinking chinese stuff), for now it is stuck on the trainer because of a wrist injury (and winter too haha).

Thank you all for your feedback!
