New project - Update

A few weeks ago I asked some questions about assembling a 29" unicycle
for road use and recieved a lot of usefull advice about components etc.
(http://tinyurl.com/ywna3)
During the thread a few people suggested that I should post an update to
let people know how I got on. Now its together and I've had a a couple
of rides on it and its still in one piece so here we go with the review
- if anyone want to ask any questions about it then jsut shout them out
and I'll try and answer them all or if any one has any thoughts on
possible improvements let me know those as well

The Machine
Starting from the bottom:
Unicycle.Com wide crom-moly hub(36 hole).
Stainless Steel double butted spokes.
Sun CR-18 700c rim.
QU-AX 127mm cranks.
VP (Shimano DX copy) BMX pedals
Schwalabe 2" Big Apple tyre
Nimbus X 28" frame
Kris Holm saddle

The Thoughts:
I started out on the project wanting to build a wheel and combine it
with something that I could get a few miles in on the road at a sensible
pace. I built the wheel up with a standard 3 cross pattern - was quite a
straight forward pattern after I'd got the lacing pattern sorted.
Putting the rest of the machine together was relatively simple with just
a bit of seat post trimmming required and everything was assemble with a
good application of copper slip

In Action:
My first thoughts are that its so fast! compared to my muni with its
long cranks the short cranks and big wheel /smooth tyre of the new uni
are very fast - mounting took a couple of attempts again, the whole
feel was so different but once used to that its a joy to ride - my two
outings so far have been 4 miles and 9 miles and have been averaging
about 8mph but thats with stops and a few UPDS thrown in.
Going down steep hills is quite a challenge but I can seem to get it up
some fairly sharp rises without any real problems. The only area where
its not been ideal ( and this is more down to my lack of skills/ability
than the unicycle) is on a half mile stretch of farm track / bridleway
on the 9 mile ride - Once off road there was almost no way my skill
would let me ride it - on the uneven flat I couldn't easily get it going
and once I did then the short cranks didn't really give me enough
control to negotiate the single track with any confidence. However, the
other benefit of the new uni is that its light so it was simply a matter
of chucking it over my shoulder and running that bit till I got back to
the road.

So in summary, its an absolute dream to ride and the satisfaction of
putting it together myself was well worth the effort - Possibly in the
future I may upgrade the frame to a custom frame and was wondering about
the possiblity of using a frame that would take a 36" wheelset so I
could simply swap the wheels over depending on what I wanted to ride -
has anyone had any experience of this? So my plan now is to get a load
of miles in and see where that takes us - Once again thanks for all of
the advice that was offered when I asked the original question

Cheers

Roland

Sorry should update my profile - am in the UK just south of Derby - I
ordered the rim and spokes, rim tape and tube from St John Street
Cycles in Bridgewater - their online shop lists everything and they're
very helpfull on the phone as well - the rest of the parts came from
unicycle.com

Nice ride. I do quite a bit of distance riding on my 26er and I'm
thinking it might be time to step up to a niner. If I do, yours is a
very similar setup to what I would get. What was to total price of the
project?

Yeah it's just about what I wanna end up with too... although hopefully
yellow! I wanted a Big Apple too, but I'm not sure how wide the rim
needs to be! I went looking today and they all seem really narrow, but
I'm not sure if that's cuz I'm used to looking at 24x3 and 20x.2.5 tyres
with big rims all the time. How wide is your rim??

Including absolutely everything, the 29incher cost a shade under 200ukp
which I felt wasn't bad given the component select that i was able to
have.

The sun CR18 rim seems to be fine - you can see a drawing of it here
http://tinyurl.com/22upa I'm only running the 2" Big apple on it,so how
you'd get on with the bigger size I'm not sure. However you could go to
the Sun Rhyno rim which is wider still - I basically looked at rims
suitable for either heavy touring or tandems when I made my choice. So
far although I've only done 4 rides on the machine there haven't been
any problmes and thats included riding off a few kerbs and a bit of
hopping. So for the 2" Big Apple the CR18 seems fine - I'm running it at
a reasonable pressure as well which is fine for the terrain I'm
intending to go on - however, a slightly wider rim might be better if
you wanted to use the wider tyre.

On the colour front, I'm kind of kicking myself I got the black cranks
and not silver ones as that would have finished the silver machine off a
treat.

Nice project, Roland. The 29er is a good one to do from scratch, and
it's so much fun to ride.

As far as interchangeable frame goes, I personally wouldn't recommend
it. The 36" wheel geometry begs for a wider hub. In addition, part of
the 29er's charm is it's lightness; that's not really a Coker feature.
It certainly would be possible, but it would not work towards preserving
the best features of each.
