I see quite a few people doing that - on the public highway, around here :roll:

Re: Which Turbo trainer?

I got a Miroura B60-R in an online sale at CRC and it's great. (paid around £60 I think)

However, looking at some of those cheaper Decalthlon ones, they don't look much different :shock:

Re: Economy Build or Buy?

Surely it cannot be possible to assemble a bike cheaper than buy a ready built one? Like for like - it is - at least in my case. The cheapest Virsa I could find (at the time) was priced at around £1,899 and that was nowhere near the spec of mine. The nearest bike I could find to my spec, was a bike...

Re: Economy Build or Buy?

As previously said - at least you had fun and you probably have more technical knowledge about the bike, than anyone else. Another thing to remember, is that it's uniquely yours - there isn't another like it in the whole world. I did the same thing, only with brand new parts. I budgeted for £1,800 I...

Re: Fork column failure on thread less forks.

BTW RS 1-1/8" steerers (and probably other sizes too, with different dimensions) are all made the same way; they are a tight fit (a push-fit into aluminium ) into the fork crown, on (IIRC) a 30.00mm diameter (which conveniently also locates the crown race). The lip at the base of the steerer i...

Re: Fork column failure on thread less forks.

I've never compared the internal diameter of an alu and steel steerer. I'd expect steel to be thinner wall thickness, but how much difference does that make to inserting the star nut in either steerer type? Alu steerers are significant thicker. I own a 1/18" Monoq fork which I had to use with ...

That was just an example, They could just as easily been held loosely, or between 4 pegs in a jig - the result would be the same.

Re: Fork column failure on thread less forks.

To answer both - as far as I know - there are only two sizes of star nut 1/1 8 and 1/5 - the latter used for tapered forks. I have only ever used 1/1 8, both on steel and alloy. The tools to insert them are standard sized too. As for butting further down the fork - i'm sure this is done on some fork...

Re: Fork column failure on thread less forks.

by how much would a fork steerer have to be made thicker to be significantly more resistant to everyday type fatigue? are all threadless steerers standardised around the same thickness? or is it 'anything goes'? For a 1 1/8th they have to be the same thickness (or pretty close) .... Internally - be...

Re: Fork column failure on thread less forks.

PS: I have never ever heard of a steel (or alloy for that matter) steerer breaking on a fork, under normal operation. Even when they are pushed past their intended use (eg DJ or Freeride on a non-suitable fork) it's usually the wheel, QR/Fork lower, or stanchions that give way first. The steerer on...

Re: Winter tyres

The Ice Spiker does come with different studs. I expect the Ice Spiker is intended more for off-road use, and that extended road running will wear the sharper spikes down to rounded studs which end up giving less grip than square studs with a similar road mileage. Can't say they have - mine are sti...

Re: Winter tyres

Those studs in the picture do not look the best quality. Those look flat (not pointed like mine) plus the seating of the outer casings look horrendous The studs in the my rear Ice Spiker Pro don't look that bad - after 7 road commute seasons and several thrashings on the muddy and icy tracks on the ...
