Pompino Alfine 11 project

Planning to finish my blue V4 build with Alfine 11 hub this weekend. I am an old bloke so rather traditional components, and all metal parts but the front light, stem and brakes are silver. I got the frame early last year when they were £99, it arrived with a 1cm chip on the back of one fork leg, sent photo and negotiated a £20 refund. Got a reasonable match with car paint touch up- a Rover colour which I can check if anyone needs it. It is just ever so slightly darker, but the position of the chip means it is not easy to spot.

Frame: Pompino V4 blue, medium- rear spread with care to 135mm using Sheldon Brown method, track ends carefully re-aligned with help of 18" adjustable spanner.

FSA Orbit MX headset installed

Token 103mm carbon square taper JIS BB installed

Front wheel stress relieved tensioned and trued: Shimano DH-3n80 dynamo hub, 32h, ACI Alpina DB spokes (could not get my usually preferred Sapim Race in right length)
Rear wheel needs final truing and tensioning: Alfine 11 hub, 36h, Sapim Race DB spokes.
Rims: Exal LX17 (17mm internal width)
Rim tape: Schwalbe HP
Tyres: Vittoria Voyager Hyper 32mm
Tubes: Conti race 28-32mm
Valve caps: tarty blue anodised from Fleabay
Mudguards: Dia Compe ENE silver alloy
Brakes: Front Shimano Sora 90mm v-brake, SwissStop GHP pads in BBB shoes; Rear old LX low profile canti, Surley cable hanger hung on seatpost clamp bolt
Brake cables: 'We The People' BMX linnear outers, Shimano SS road inners
Gear cable Shimano SIS/ Shimano stainless inner.
Bars Planet X Strada Compact Lite 7050 400mm
Bar tape: Vavert blue cork gel, cheap from Fleabay
Stem: On One Hot Box 90mm
Shift/brake levers: used Versa 11 from Fleabay
Saddle: Spa Cycles Wharfe leather (like B17 narrow)
Seat post: something silver from back of garage
Crankset: Spa Cycles TD2 double 165mm
Crank bolts and chainring bolts: Jtek stainless
Chainring: Surly stainless 34T
Sprocket: Sturmey Archer 1/8" 22T
Chain: KMC B1S
Rear rack: Tortec Ultralite, used from Fleabay
Rack bolts: Ti Grade 5 mushroom head
Brake bolts: stainless mushroom head
Mudguard & bottle cage bolts: M5 15mm caphead alloy screws in silver, may need cutting to length.
Lights: Front: Hermann H-One S 90lux dynamo LED lamp; rear Spanninga Solo XDS dynamo rack light.
Also silver Tortec alloy bottle cages x 2, silver Shimano M520 SPD pedals, Shimano SM-PD 22 pedal reflectors, am I forgiven now? ;-)
Seatpost clamp: could not find a reasonably priced silver one so bought a black one to swap with the silver one from my Claud Butler Dalkesman touring bike, which has a black headset anyway.

What have I forgotten??

Jobs done over weekend:

Final tensioning and truing of rear wheel
Assemble and fit chainset
Fit pedals
Fit front brake
Fit levers
Fit brake cables
Wrap bars
Fit rear rack
Fit rear sprocket and gear selector 'cassette'/ cable hanger on rear hub, plus cut and fit chain.

Chain runs nicely with no tight spots, axles about half way along dropouts and 42mmish chainline seems good enough. With the 103mm BB and Spa Cycles TD2 double chainset, chainring is on the outside and cranks are passing the chainstays at about 4mm clearance, so Q Factor is approaching the minimum.

I used the anti-rotation washers for vertical dropouts which angles gear cable upwards, so cable will be running along top tube and back of RH seat stay, which will hopefully keep the weather out better than running along the chainstay, which creates a low point in the cable where I know water and crud can collect from previous experience with a Nexus 8 hub-problem could be worse with Alfine 11 as cable has to run up to a higher position above chainstay, as opposed to below on the Nexus 8.

The Alfine 11 cable has an extended bellows arrangement at the end to help keep muck and water out with usual arrangement of the cable, but I have heard that this is easily damaged and can get caught up in the selector quadrant, so I may not even fit it.

Tyre clearance with the 32mm Vittoria Hypers* (which measure 33m wide on a 17mm internal width rim) appears just about adequate to fit the mudguard at the rear at the current axle position and fine at the front, plus the cable of the 90mm v-brake at the front has plenty of height over the tyre.

I run the same brake arrangement on my tourer: a 90mm Shimano v-brake up front (Tiagra on the tourer, with 37mm tyres and mudguard) and low profile LX canti on the rear. The (midi?) v brake works well and is plenty powerful as a front brake, the rear canti is less powerful, but still enough to lock the rear if used in anger as weight transference does not give much grip at the back in any case, plus the canti works better with a rack on a smallish frame.
