Re: Alfine hub questions

OK, I ought to know this, I possibly do, but better safe than sorry. Three questions: Alfine 8 hub 1) What gear is a hub without a cable in, has it gone back to 1 or does it remain in the last gear it was in, if the latter how do you tell which that is? 2) there's two trigger shifters, that operate...

Re: Single source for rim ERDs?

I’ve also happily run 32mm (and 35) on open pros but there’s no denying they feel a lot better on a wider rim, especially at lower pressures. Do you have any rims in mind Samuel? I wouldn’t let your existing spokes dictate too much unless there’s a happy accident of ERDs I’d just assume you might ne...

Re: Is it possible to repair this tyre?

As mentioned above, check from the inside that the casing isn't damaged (pin prick hole is fine), if the casing is OK then put a patch/boot on the inside for piece of mind, you could probably just carry on riding it at that point and see how you get on, but if it were me I'd also use flexible superg...

Re: set back seat post ?

Torso length does not determine saddle setback, in case it hasn't been stated already. But set back does directly affect how much weight you have to support with your core or hands. So with a longer torso to support more setback effectively counterbalances your top half. Steve Hogg explains better ...

Re: set back seat post ?

I am also short of leg and long of torso and run a lot of setback, to counterbalance the cantilever of my upper body. Also tend to run longer stems or long reach bars as my short legs require 52-54cm frames but I prefer a 54-56cm top tube.

Re: Spa Audax crash damage – fork?

If Reynolds do make lighter/thinner tubes than those in that list, I suspect that they will only be purchased by (and may only even be available to) a small number of true custom builders I was thinking along opposite lines, namely that you'd only be able to get custom product if you were willing t...

Re: Spa Audax crash damage – fork?

Re the experiment with Spa CF vs Thorn plain-vanilla. Did you find that there was a noticeable difference in ride quality? I partly wish I hadn't cannibalized my Dawes Audax to build the Spa Ti bike - It would have been interesting to compare the Reynolds 531c and 1" steerer with the Spa CF an...

Re: Spa Audax crash damage – fork?

I had 5 mins on my hands... Above and beyond, but very interesting, thanks. It was as much for my benefit as anyone else ;-) One fork I do want to weight at some point is the one on the front of my Dave Yates built 653 Condor, I don't know what blades it uses but it is the best riding fork I've eve...

Re: Spa Audax crash damage – fork?

the listed dimensions may be the same but it's not specified if the butting profile is actually the same?

ie: two blades listed as 370mm x 1.0 - 0.6 could differ thusly:

Re: Spa Audax crash damage – fork?

I wonder how much of SJS’s Reynolds 853 fork’s weight is in the 380 mm steerer tube. They say it weighs 895 grams, which isn’t that much lighter than the cheaper steel forks mentioned above. But maybe the fork blades are significantly lighter. They’re certainly thinner than the Surly blades. I thin...

Re: Spa Audax crash damage – fork?

Aye, horses for courses and all that, but Brucey's point is very valid, for close bunch riding and chaingangs a higher trail bike is definitely more favourable, especially if it's what you're used to. My 'fast' bike is very traditional road race geometry and better suited when I'm out on a fast grou...

Re: Spa Audax crash damage – fork?

Understood. I suppose it needs less leaning to steer no-hands with the shorter trail? Mostly yes, although the overall feeling is, to me, more responsive, others may call it nervous. A lot of my riding is on backlanes and moorland roads, lots of dodgy surfaces, and tight turns, funny cambers etc. a...

Re: Spa Audax crash damage – fork?

The surly branding on my disc trucker forks was just a bunch of thin individual stickers and peeled off very easily, I imagine the pacer forks are the same. If it were me I’d be tempted by either the thorn 853 or getting a builder to make me a pair, but that would be the most costly option and may n...

Re: Spa Audax crash damage – fork?

FWIW, I've run one of the above on my Ti Audax with no ill effect despite the longer A-C height, I was running a 55mm offset version as I wanted to try the bike with a bit less trail. Thanks very much for your detailed list of candidates, amediasatex. Regarding the above, what were your conclusions...
