Hebie have now manufactured a rear end of their chainstay that doesn't rub and I can see it moves around very freely after just putting it on.

Titanium? Rust? No way! I'm still acquiring components - so far I have the frame, fork, headset, lighting, SS Velo Orange fenders, Reecharge charging system, v-brakes and the Rohloff Speedhub and Son Dynamo hub are built into the wheels and ready to go. The titanium seatpost, stem and handlebars I will probably order in a couple of weeks, and also the brake levers, grips, cables, rim tape, tyres and tubes, chain, pedals, and racks. Also I didn't much like the first chainset I ordered so another one is on the way.

It will probably be another couple of months before it's on the road, but it will be worth the wait - in the mean time I'll just have to make do with riding my Sabbath Silk Route.

Hey Padre. been searching the thorn website 9 (and PDF's), I cant find the BB drop for the nomad. Maybe you could share some light on this mystery?
Estimate will do.

Just went out and measured mine. It comes out at 3.5cm drop, with some variability depending on just where the BB is in the EBB.

It's an old one, but a great review of the Rohloff in use (for MTB trail riding) compared to derailleur gears

Adman 04-08-2004 06:16 PM

--------------------------------------------------------------------------------

Not only is it neat technology, it's the most durable mtn. bike drivetrain that exists today. Hard XC riding?:) Yeah, you could say that...

As a heavy rider (210-215 lbs is my average body weight, plus gear) with long legs & cranks (180mm), I was having drivetrain reliability issues on my heavy trail bike. Riding year round in New England is probably as heavy duty use as a bike drivetrain can get-mud, snow, ice, water, road salt don't make it easy on anything that's exposed and under an enormous load. Warped cassettes and a fistfull of worn chains used to clutter my bike workspace..Well, since I got off the Shimano wagon & switched to a Speedhub 2 seasons ago the drivetrain maintenance on my heavy duty trailbike/freeride bike (an Uzzi SLX) has been reduced to virtually nill In 2 seasons I've had to replace a cable set and a chain tensioner spring. On my XC race bike during the same interval (Shimano/SRAM 3x9 drivetrain) I've had to replace several chains, cassettes, chainrings, shifter cables, and a rear derailleur.

Speedhubs are sealed against the elements and run in an internally-lubricated oil bath.
Heavier? Sure, but last year's maiden voyage in Moab proved it to be a sound investment. On our first mid-March ride on vacation, we embarked on what would turn out to be a 35 mile epic ride, through several hours of heavy, wet snow, suck-your-boots-off mud, and finally with several screaming downhill fireroads and high speed stream crossings. During the ride my bike shifted perfectly the whole time. Several friends with conventional drivetrains had to stop, scrape the mud from their chainrings & cassettes, and after the ride more than one had to do a drivetrain overhaul to get original shifting behavior again. I just hosed off the Speedhub & chain & hit the hot tub:)

Conventional drivetrains are fine for many riders-lightweight, very careful shifting, favorable weather/riding conditions, regular cleaning, and luck can contribute to great performance and long drivetrain life. I'd rather ride more & be lucky less:) There's a Speedhub#2 in my garage that's going on my XC bike this spring...

Well it's 10pm here and my bike is also ready now. So I took it out for a little trip. Road up the hill for 100m and down for 400m and back 200m back to house. OMGosh 1 on the rohloff is soo easy and I love the light from the new Supernova E3 triple now. It was lighting up the road very nicely with 1 led! When I get commuting on it, I have a dark area with no lights I'll show difference from the Supernova E3 triples and older Ayup's lights on different nights with speeds as well. Can't wait to take it on a proper ride!

What took you so long?

They are great, but I'm keen to know how / where you mounted it?

Bought mine with the multi-mount thinking it would bolt onto the tube at the top of the forks. My plan was to lock it on using a Pitlock. Sadly the diameter of the hole in the Nomad was too small and doesn't go through both sides of the tube. Briefly considered drilling through, but ended up getting the handlebar mount. It's convenient because I can easily dip the lights, but too easily snaffled with just a rubber band holding it in place. The only solution seems to be getting the gold connectors and removing the light every time I leave the bike for 30 seconds or more.

:shock:

Never a good idea to go hitting up a new frame with a drill.

I found similar problems. The hole in the fork crown is actually a threaded 5mm bolt-hole, so any common hex-key bolt will do. Can't quite see the bolt in this picture.

Image


My added problem was a glitch with my Nomad - just one flaw, the hole in the crown had not been drilled/brazed correctly in-line. So my light when fitted shone off at 5-10 degrees to the left, just enough to be fairly disconcerting when riding. I have ended up heaving on the multi-mount enough to line it up, without breaking it :wink:

Would you believe 4 small things that are absolutely critical on a bike called brake pads! In disgust I ended up getting the Kool Stops from Wiggle that are suited for CSS rims. Unfavourable reviews, but I'll see how they really go myself. I also have some SwissStop Blues coming from Bike24, I just hope they don't screw up like starbike did...

I have my Supernova E3 where il Padrone has it. I too was looking for the hole through the forks... I wonder why Thorn have done it like this, means I'm going to have to modify the standard installation of the SKS chromoplastics to have them bolted on underneath. I have the gold connectors installed for my rear light already and considering installing them in on the front.

Well that has to be more secure than the rubber band. I'll give it a go.

The only problem I've had with Bike24 is slow delivery. I ordered the E3 from them before ordering the Nomad and it arrived two weeks after the Nomad. Could be because they use Australia Post to deliver at this end.

I've been using the Swisstop Blue pads, but got a bit concerned about braking grip losses on some of our recent wet day commutes. They seemed to feel disturbingly like the old steel rims :shock: , so I'm hoping the Koolstops for CSS that I've recently received will be better in the wet. In 2 weeks I am running a ride up Mt Donna Buang with good chances of snow and/or wet conditions and I want brake grip on the 16km steepish descent.

You may have seen this post on the Thorn site, which may give some comfort.

http://www.thorncycles.co.uk/forums/index.php?topic=2680.0

There was also another more recent post where someone cleaned up the surface of their Swiss Blues with some agent or other and experienced greatly improved performance in the wet. Might be worth trying meths as they are obviously the bees knees when it comes to longevity.

I went looking for these on Wiggle to read the reviews you mentioned, but could only find the olive pads which are made for ceramic rims.

Did Wiggle have the carbide pads when you ordered?

I don't believe Wiggle stock them. However SJS Cycles do, and they're a bit cheaper than the Swisstop Blues.

Yep, they're different. The ones at SJS are specific for CSS rims. Black in colour.

First proper ride with it today. If I was using this for Audax rides, and not planning a tour, I would have a bigger chainring. I found myself in 11 most of the time.

According to Andy Blance in "Living with Rohloff" you've probably got it right. He says:

"11th gear is direct drive and should be the most efficient; consider this ratio carefully because ideally, this would be the most used gear."

Now having ridden in the wet on my Koolstops in the yucky colour I can comment. There is a definite loss of braking power I have noticed compared to dry. They take longer to grip as well. Just checked brake wear and I believe I can see some. On wiggle the reviews say they didn't last 50 miles, well these have done 115kms so far in dry & wet conditions and there is definite loss of brake pad material

Sorry for the thread revival but can I ask whether anyone has resolved this wet weather issue with the CSS rims? I'm considering going this way but wet weather braking performance is a definite requirement...

Thanks!

You've pointed these facts out pretty well :P

The problem with the rear drop-outs is that as your chain wears and you need to adjust the chain tension via the QR axle position, your wheelbase varies and you'll need to reposition your disc brake calipers. Simpler with the Thorn and the EBB for chain tension.

Yes, that is exactly what I was alluding too. And how fiddly must it be removing the wheel to fix a flat.

Well, we all know that since I made that comment, Wingnut has acquired a Troll of his own, so I wonder why he didn't show us a picture of the dropouts on his bike.

But in any case there was no need for him to feel defensive about it. In fact, he has obviously forgotten about it now, but I paid him this compliment:
I've never seen a picture of a completed Troll before - and looking at pics of the bare Troll frame I thought all the unused attachment points would be a little fussy and untidy. But now I can see they are hardly noticeable. For anyone looking to build a bike your example gives plenty of incentive to consider the Troll.

However, after looking at Wingnut's close-up shot I've changed my mind - they do look fussy! Now, let me share a couple of pictures showing how the dropouts will look on my soon-to-be-completed project, which uses an EBB similar to the Thorn.
