Q: Truvativ Elita triple, is it a road or MTB c/set?

Do you know if the PCD for this triple chainset is 130 (road), 110/94 MTB (5-arm std/compact)? Maybe they do multiple models under the same name. I want to run a 32-ish ring on the middle (not inner) as a single-speed chainring, but want to make sure this is suitbale c/set to cannibalise (BTW, I don...

Now I just need to know if I want/need near field illumination? Decisions, decisions! I would say it depends on your speed and road conditions. Riding 20+mph on unlit country roads I'm not bothered about near-field illumination, by the time I see something that close it's too close to avoid. If you...

Don't know the wiring details of this light but the explanation that comes to mind is that you have wired the dynamo to the tail light connector and the tail light to the dynamo connector. Russell Can't do, dynamo cable is integral to the lamp. So only connectors visible are for a 2nd lamp (rear/fr...

I've an IQ Fly senso, like yours with off/on/auto switch: OFF - is what it says, no output at all and that includes the standlight. ON - always on AUTO - on when dark If running on/auto and come to stop and swith to off, then no standlight. Switch to on/auto and then standlight will come on. So, in ...

I too can confirm the Marathon+ puncture proofness (this time the 26x1.3 running at 95psi). 7500 miles, without a single puncture, then 1/2 dozen in a month and I binned them. By then the tread was badly cut but still reasonably deep (>1mm) but since they no longer repelled those shards of glass the...

It never fails to amaze me what a wonderful resource this forum is, thank you!

Adopting the simplest solution, I'm going to use a smaller box and with an LBS not 1/2 a mile away they've supplied me with a box that should meet parcelforce's limits.

Q: Who to use to post a bike?

Hi Folks, I need some help please... I've just boxed up a bike (complete, ready to roll) and its dimensions are: 175*115*25cm. However, it's too big for Parcelforce (they say 3m max girth and this is 4m). Could anyone suggest who I could send it with please? CityLink is £40+VAT so anything cheaper w...

Cable is flat along the fork... so it's not that. I stupidly shifted the sensor/tx to the rear wheel last night, thinking the sensor was being affected - despite knowing the computer works if held in my hand, doh! Going to try some Cu pipe sponge insulation to take it off the bars and if that doesn'...

I've the sensor on other fork-leg to dynamo cable. The signal from sensor to computer appears to be fine because I hold the computer off its clamp and it reports correctly. I can even hold the computer near to the light (without touching it and it works). However, when on clamp on bar (other side of...

I'd work my way around each spoke in turn, +1/2 then -1/2. Don't do just RHS then LHS, else you'll end up with a wobbler.

I don't think that you need to re-dish the wheel.... If the centre of the rim is centred between the locknuts of the hub it will be centred between the dropouts of whatever frame it is fitted to. This is spot on, good answer. A true wheel has the rim centred between the locknuts. If the OLN is 135m...

Are you sure that this would provide 'a wider spread of closer-ratio mid-range gears' that you're looking for? Are you not forgetting that you'll be switching both chainrings and spockets to make incremental/sequential changes in your ratios? If you want to have close ratios between gear-inches for ...

Screeching could be your pad alignment. If they're not toed-in (a little) at the front and therefore contact more fo the surface to the rim when applied, they may well squeak.
