Re: leather tape adhesive advice

Wiring loom harness tape = Electricians friction tape.

The Tessa tape looks very nice, I'd use that.

Re: FSA Gossamer crankset upgrade

The bike shop told me FSA stood for....

Fairly Soft Alloy

Shimano GRX is equivalent to FSA Adventure cranks.

Re: Struggling with cantis

My advice is to fit a dual pivot brake at the front. Cantis are more trouble than they are worth. Some people claim they can set them up so they work well but I can't. It must be a very special skill. The Universitys of Warrick and Manchester, both use cantilever setup as an entree to Engineering S...

Re: leather tape adhesive advice

If the leather tape has rough, unfinished back.
First wrap a layer of Electricians friction tape, the black cloth tape that is adhesive on one side, tacky(sticky) on the outside.
(Some please translate the above sentence into British) :)


Then wrap the leather tape, over the friction tape.

Re: What milage do you get with a Bosch Drive?

[ Yes, I am aware of this but just wondered what folk got in practice Al Bionx 350w, 10ah battery, 40 miles will use 30% of the battery, 1200 feet climbing. 35 miles 2100 feet climbing, 40% battery used. Note that regen is used on the downhills, descending and climbing are pretty equal on the routes.

Re: choice of 3 ebikes? which one...

2) Orbea F30 Gain

I'd pick this one, only 1 of the 3 that has double chain ring up front.
It is a standard Shimano road crankset.

Some Cannondales have a double up front too, the Synapse E.Bike,
Cannondale make their own chainsets for that one, it is a Bosch
system bike.

Surly Troll, 26in wheels in all frame sizes.
Disc or rim brakes. The rim brake studs are removable.

Re: Which tyres are the easiest to change on a Road Bike?

What rim tape ?,

For tubeless ready rims, even when being used with tubed tyres,
use tubeless rim tape.
Even for some tubeless unready rims, tubeless tape can make it easier to mount the tyre.
DT440 with cloth tape, 'orrible, with tubeless tape, tolerable.

Re: Campagnolo Centaur 2002 crank arms and bottom brakets removal

Note, that being an Italian bicci, the bottom bracket is right hand threaded on BOTH sides.

The Italian system is much superior, according to Old Potatoe.

Re: Dia-compe ENE wing shift levers

That would really irritate me! You either want it to be indexed or not! The Power Ratchet mechanism is to prevent the cable from slipping, ye olde Campag friction shifters would change gears when you stood up on a hill and the frame flexed a bit. The ratchet prevents the cable from being pulled bac...

Re: Does anyone know this crankset brand or any information on it?

TA makes chain rings in large number of formats.
It is handy to be able to buy new chain rings for a 50 year old crank.

For reference

Re: Can a modern day bike have longevity or do changes in standards make them obsolete or hard to maintain in the long r

Some bikes are purposely designed to use the bits you have in the shed, or in the bike shops back room, full of slightly out of fashion stock. I had Black Mountain Monster Cross like that, Surly has frames like that too. You just need to look around a bit. Like this brand new $10, 5s friction rear m...
