Title: MartinF's Raven Sport Tour
Post by: martinf on October 11, 2016, 09:51:33 PM
Finished building up the red Raven Sport Tour clearance frame I bought earlier this year, just before the last ones in my size went.

I've set it up for on-road use, for day rides and possibly short tours with minimal luggage use, just a Lord uplift and large Carradice saddlebag.

After considering a Nexus 8 I finally decided to splash out on a Rohloff.

No Chainglider on this bike (yet), but it might be possible later on if I change chainring size.

A mix of new, old and NOS parts, the latter include XTR brakes, these were on special offer at my LBS.

Several years ago I bought a stock of TA Cyclotouriste rings from a bike shop that was closing down, which explains my choice of crankset/ring. I'm starting out with 50x19, but have plenty of other sizes available to try.

Tyres are Kojak folding 35 mm, but I have clearance for 42 mm Supremes if I decide I want more comfort.

I got a B&M IQ-X front lamp. My initial impression is that it isn't significantly better than the B&M Cyo I have on other bikes.

This is the first time I have used compact drop handlebars, so I have left them untaped for the time being in case I want to alter the brake lever positions.

Absolutely stunning build, Martin; all compliments your way. I think the T/A cranks and rings look magnificent on it.

Yes, wise to leave the compact drop 'bars untapped till you can ride/play with them a bit.

All the best,

Dan.

There is something wonderfully juxtaposed about the build. I love the contrast of the classic chain ring, leather toe straps. pedals  and shallow drops combined with the  rohloff etc. I was also struck by how close the bottom of the drops are to the secondary brake levers ( must be a 'proper' word for them) Nice one!

Ian N-1  :( For now!

Nice clean lines, Martin--the red and black set off the bike's lines very well, and the silver detailing makes for a sharp contrast.  Enjoy!

Old school style combined with a modern rohloff transmission..

Well done !

What is that that I spy on the rear rack mount in the third pic?

Address plate.

Used to be mandatory here in France.

A relic from the days when cyclists had to pay a yearly tax on their bikes. The tax was abolished in 1959 and the address plate became facultative in 1995.

I still fit them to the family bikes, with the hope that if a bike is stolen by a casual thief and then abandoned I might get it back.

Superb build Martin, love your setup.

You did well to get the XTR brakes, they go for ridiculous money secondhand.

I bought my RST with flat bars although if I was to buy again I'd spec drops now. Looking forward to hearing how it rides

Best,
Neil

I originally planned on getting a more basic model of brake, but the mechanic I know at the LBS had had the XTR en stock for a few years, he persuaded me to buy the front and rear set for 50 euros.

There was a posting on the forum recently about the need for a special washer when fitting the Rohloff cable hanger to XTR, so I wasn't caught out with that during the build.

The RST build is the first time I have set up the Rohloff shifter cables, I did have a bit of trouble with this, at one stage I undid the wrong grubscrew and had to take off the bellows to refit the internal cable.

I had a spare "Easy" internal cable set in stock in case I bodged things completely. But I reckon it was good training doing this in the workshop at home, it should make it easier if I ever have to do cable replacements on tour, probably not with the RST, but more likely with my Raven Tour.

One thing I could have done better is the brake cable adjusters. I used in-line adjusters, which add another break in the cable housing, as I forgot to order the special noodles with built-in cable adjusters, which are neater.

The bracket for the Cateye rear lamp is also a bit ugly, but it was the only strong steel bracket I had in stock that would easily fit in that location on top of the mudguard. I like having two rear lamps, the generator powered B&M Secula mounted lower down on the mudguard is very lightweight and gives an even patch of light that is reasonably visible to traffic approaching from behind, whereas the Cateye LD1100 is a "point" source, with 6 LEDs pointing directly backwards and 2 LEDs pointing directly sideways on each side. This increases side visibility significantly, particularly important on roundabouts and road junctions.

I'm a big Chaingliger fan.
Did you fit one?
Title: Re: MartinF's Raven Sport Tour
Post by: martinf on October 16, 2016, 06:17:02 PM
Not yet, there isn't a Chainglider for 50x19.

50x19 gives a gear range of about 18" to 95", which is a slightly lower top gear than I have on my old derailleur lightweight bike, but a higher range than on my Raven Tour, the latter has 37x16, so about 17" to 89".

Not had the time to ride the Raven Sport Tour much yet, but I reckon the 50x19 combination should be about right for me.

I think a non-Rohloff specific Chainglider rear part for 18-22 sprockets would probably fit without rubbing on the Rohloff hub, and Chainglider front parts are available for 48T, 44T, 42T and 38T ring sizes, so a Chainglider may be an option in the future if I reduce the gearing a bit.

I have 42, 44, 46, 48, 52 and 54 size TA rings in stock, so it will be easy to increase or decrease the gearing.

I couldn't get a chainglider to work on my 536l RST. The clearances were too tight. Your larger frame might be better I suppose. It did go on but didn't glide like on my Raven tour and rubbed on the frame.

My Raven Sport Tour is the biggest size, 611S.

I borrowed the Chainglider D18 rear part for 18-22 sprockets off my old 650B bike, and tried it (without the front part) on the RST. It seems to fit without rubbing on the seatstay or the Rohloff hub, but I can't test it in operation with my current chainring.

Finally got around to taping the bars (over the foam).

I've been using the bike with just the Grab-On foam up till now.

Also changed the location of the shifter, from accessory bar to Hubbub at the RHS bar end.

Very nice, I think that red is the best red I've seen on a bike, one of the few colours that look good whatever the light and better in reality than in a photo.  But IMO (And I know I may be obsessive about it...) the first thing I see on your bike is all those zip ties!

Beautiful bike Martin, looks the business. Those handlebars looks very comfortable indeed. I've got a flat barred Sport Tour that I had from new and love it for my commute to work although if I was buying again I'd opt for drops like yours.

Regards,
Neil

Nicely done, Martin, and the red-with-black is splendid.  (Red is my preferred colour, but I chose black for my Raven with a view to making the bike as unobtrusive as possible, with just the alloy 'guards for a bit of zing.)

Those handlebars looks very comfortable indeed.

I was a bit sceptical at first with these shallow drop bars, an idea that I (again) copied from Dan.

But after using them for some time I now prefer them over the more traditional drops I have on my Raven Tour and my old lightweight derailleur tourer.

On my Raven Sport Tour I use 4 hand positions in order of increased aerodynamics - on the tops (this is for urban riding to see over the tops of cars. I have auxiliary brake levers for safety), on the hoods (braking possible, but not full power), holding the brake levers fully (hands usually here on fast descents), and hands on the lowest part of the drops (no immediate access to the brakes). I very rarely use this last position on my two other drop handlebar bikes, it is much more comfortable with these shallow drops.

Function over beauty. I like a hub generator rear lamp. And on this bike I have a cadence function, so another wire. The easiest way is zip ties.

Much less visible on my black Raven Tour.

I also have a front reflector, but it must be reasonably unobtrusive as Jags hasn't yet told me to chuck it over a hedge.

 ;D ;DMartin you can get RED zipties ya know  ;)
lovely bike buddy i don't think i'd be firing anything over the hedge belonging to that beauty, well ok the zip ties maybe but other  than that  the job's a good one.

anto.

Nice bike. I like the red.

I don't mind the zip ties. To some people, they may detract from the visual aesthetics of the bike. But to me, they are a simple solution to an engineering problem (cable routing). To each, his/her own.

So glad they're working out well for you, Martin. They continue to work well for me also; perhaps my close-second favorite to randonneur-bend 'bars.

Fantastic job on the bike; looks fast just sitting still and a real joy to behold.

All the best,

Dan.

Lovely mounting Martin, you have eye for detail , well done
