Re: Shimano 12-speed

I note there are no SLX 135mm OLD hubs anymore ... its either 142mm, 148mm (BOOST), or a (new?) 157mm size.. good job I have a hoarded 135mm one !!! :-) I wonder if we are going to get touring/trekking bikes starting to use Micro Spline hubs rather than Hyperglide at some point ? Currently you woul...

Re: New budget touring bike 2019? Asking for a friend.

Do discuss with your friend what he/she would be comfortable riding. Given the weight issue you alluded to they might be better off starting with a strong, comfortable upright "trekking" bike with cushy tyres...rather than a drop handlebar touring iron designed for fit and fexible veteran ...

Re: Shimano 12-speed

... FWIW: SLX drivetrain 1x11 £337 RRP reduced to £223 on CRC .... This makes 11-speed look a bit silly at the moment, as you've just got SLX at 11-speed, BUT the solution for Shimano is fairly obviously to 'upgrade' Deore to 11-speed and Alivio to 10-speed, so they've then got two groupsets each a...

Re: Failed B & M Lumotec IQ2 Luxos U

Unfortunately my IQ2 decided to pack up 6 months out of its 2 year warranty - I thought it had a 5 year on it but I was sadly mistaken. It started playing up over the winter by turning on/off charging more and more intermittently and by spring it just had a amber light occasionally blinking with no...

Re: Securing stuff to rack top?

I am using 30 year old MFI nylon roof rack straps on mine - I originally got them for holding my windsurfer to the car roof rack. They have metal buckles so I can strap my extensive luggage on tight. I could probably do with a neater setup though ... so interesting to read this thread :-)

Re: SP dynamo hubs - narrow flange spacing

FWIW .... The old hub (after a few year's use) had suffered a gradual bearing failure, so was still turning smoothly enough, but with ever-increasing free play in it. IME this isn't at all uncommon; most of my chums who have had these hubs and have also 'put the miles in' have had similar experienc...

Re: SP dynamo hubs - narrow flange spacing

I would be keen to hear from other SP owners how long their hubs have lasted. My SP is on my wet weather Audax bike and has done a little over 3500 miles so far, it's had numerous horrible horrible drenchings including two of the wettest 200's I've ever done where it's spent the whole day being rai...

Re: SP dynamo hubs - narrow flange spacing

regarding failures in hub dynamos these fall into three categories; a) electrical failure; e.g. wiring goes open circuit b) foreign objects inside generator itself (eg rust particles) c) bearing failure regarding b) most types of generator can occasionally end up with condensation inside and this c...

Re: SP dynamo hubs - narrow flange spacing

Here's the thread which referred (in 2017) to a refurbishment service: https://forum.cyclinguk.org/viewtopic.php?t=112106 I guess the bearings will start to feel rough, but can be hard to tell when the dynamo cogging effect (electromagnetic resistance) is very marked when rotating the axle by hand....

Re: Titanium seatpost that is all titanium

Interesting, thanks for posting that. ...... But if I go for aluminum, I'd get a similarly long one, and replace it periodically. Certainly sooner than 25 years! Fair point about me not replacing the seatpost in 25 years Mikey. maybe I was a bit asleep at the pump on that !! Its actually got me won...

I wouldn't like to comment on your existing wheels,others may be better qualified.

Re: SP dynamo hubs - narrow flange spacing

I've got one too. Don't think the bearings are user-serviceable (can see no way to access) but I gather the distributors (Ison?) offer a refurbishment service for bearing replacement if you send the hub back to them. I will have to look at that option bgnukem. I do about 3000 muddy commuting miles ...

Re: Titanium seatpost that is all titanium

Does a seatpost fail, snap suddenly, or does it warn one first? Mine started to "recline" and then just fell away. I was cycling up a 1 in 4 hill at the time, in the saddle, and as the saddle reclined i just took up the load on my legs, pedalled for a while standing up, and then stopped n...

Well my home built SP dyno wheel (36 spoke 26 inch Ryde Zac 19 rim) survived my week long french camping tour (46lb total load) without going out of true.. After a brief off road excursion my rear LX/Sputnik rim DID need retrueing slightly..admittedly its the rear where all the weight is though... M...
