Re: Specialized Tarmac SL3 forks

I think you just have to work through all the alternatives....brake type, axle type, offset, axle to crown race length, flat or conical crown race seat, and there are probably more. I happen to have a Kineses fork on one bike, their website is pretty informative https://www.kinesisbikes.co.uk/Catalo...

Re: Bottom bracket removal (help)

We don't at the moment know if the cup is actually tight/corroded into the BB shell, or if it was just a poorly-fitting tool which chewed up the splines. In the absence of a large workshop and specialist tools, my first approach would be to use something like a T hinge https://www.screwfix.com/c/sec...

Re: Bottom bracket removal (help)

aluminium cup? Possibly it is corroded in place (Ti frame...?). Two near-radial saw cuts in the cup about 1/2" apart, then chisel out the section between. If the cuts are made carefully you can avoid scarring the inside of the BB shell, leaving a just a sliver of aluminium cup for the chiselli...

Re: Bottom bracket removal (help)

Alternative....2 really big washers, one each side of the cup, bolt/nut through the middle and screw it out with the bolt/nut

EDIT picture of fixed cup removed like this....https://www.genkin.name/wordpress/wp-content/uploads/2016/03/IMG_20160317_232735-825x510.jpg

Re: Bottom bracket removal (help)

Flat piece of steel just too wide to fit inside the cup.
File or hacksaw 2 notches opposite each other on the inside of the cup.
Use flat bit of metal like a screwdriver.

Re: Bottom bracket removal (help)

Even if the replacement unit is the exact same part number, and even if the new part is manufactured on the same continent as the original part, there is no guarantee that the outside dimensions are exactly the same. There is no requirement for the outside dimensions to be identical if the unit is f...

Re: Bottom bracket removal (help)

Don't remove the other side of the BB 'to relieve the pressure' as someone has suggested.... Provided the BB unit can be removed from the driveside without damage, its a perfectly reasonable thing to do. The BB unit tightens up against the BB shell. The retaining cup the other side only tightens up...

Re: Bottom bracket removal (help)

If you can get the cartridge out (using a well-fitting tool!) then you will be able to get the remaining cup out with the old-type BB fixed cup remover, or a modification of it.. https://www.bing.com/images/search?view=detailV2&ccid=mWLbKgdN&id=E79B51CC4777417E322DF253C50BC2E6F9A4BE7B&th...

Re: Sand the finish off steerer to help install crown race?

Ah...I have a Tange Technoglide headset with a mismatched crown race (probably for a Falcon) and another one with the correct crown race. I think they sometimes get mixed up at the factory, since they look incredibly similar. You'll need to get a replacement, and ensure Spa check it first. I assume...

Re: Sand the finish off steerer to help install crown race?

Headset: Tange Terious SRN, Fork: Spa Wayfarer with matt black steerer. I can't seem to fit the crown race to the steerer. I have an installation tool and I have greased the race and the steerer, but it just won't go on despite bashing hard with a rubber mallet on the end of the tool. Was wondering...

Re: Gravel under 3000€

These expensive bikes are designed to be ridden by experienced cyclists and need regular maintenance by expert cycle mechanics. As a general rule, for practical transport (to work) I would avoid hydraulic brakes and cables which run inside the frame tubes; I would want mudguards and a way of carryi...

Re: Gear indexing and possible misalignment

Yeah, nutted axle = pressed steel hub and screw-on block.
Unfortunately this is not a recipe for a long and trouble-free relationship with your bike.
But the learning curve will be worthwhile, at least in retrospect.
