Re: Tubeless tyre question.

My current sealant is 'Joe's No Flats'. It seems to stay liquid longer than 'Stans' and 'Muc Off', which I used for a couple of years. I checked it today after 4 months of regular mountain biking and it had gone from about the original 60ml to about 30ml You don't have to pull the whole tyre off to ...

Re: E bike conversion

To echo the previous post, go for a rear drive cassette hub. Yosepower are really good suppliers, I have fitted several, all being used in a very hilly part of Cornwall

Re: Nomad/Bafang?

A Bafang BBSO2 or smaller BBSO1 will be ideal for your bike, or try a Tongsheng TSDZ2 mid drive; these are just as easy to fit, a bit lighter and the bike is a bit easier to pedal with power switched off. If using a downtime battery, you have to use rivnuts to fit the holder onto your frame. I just ...

Re: Living without owning an internal combustion engine

I would like to thank the original poster for opening this very interesting and important discussion. I managed without a car throughout the 1990's whilst living in the city (and running a bike shop); I did hire a van occasionally. I now live in rural, hilly Cornwall and still cycle most days, but I...

Re: Bikes that will take a Bafang BBS02?

Dave, I think you can fit them to most normal looking hardtails with threaded 68mm bottom brackets. I haven't done one with a pushfit, but I think it might work. As you mention, the only issue can be the chain stay flaring out too close to the bb and fouling the Bafang casing; a careful tap with a h...

Re: Goatlinks and Expander Sprockets - Good Idea?

Hi UpWrong, I've fitted Works Components 40t and Superstar 40t expander rings both worked very well. I haven't done any recently as quality 11-42 cassettes have dropped in price, the Deore are good and the better Sunrace one I've had on my mtb for over a year, it's excellent. I agree with Brucey abo...

Re: Goatlinks and Expander Sprockets - Good Idea

If it's 1 x 10 then you should be fine without the goat link. Just screw the 'B' screw all the way in. I've done several conversions, using that mech with 40t expanders and with new 11-42 cassettes. I haven't tried it with a double chainset, but I don't see a problem.

Re: E bike conversion

Can I recommend a crank drive motor, such as this Bafang BBSO2 which I've fitted to my 27.5 hardtail. Easy to fit, low centre of gravity and the bike pedals fine with it turned off. I put a big 15ah battery on, which lasts 4-5 hours off road, but a 9ah would be ok and much lighter. I used to ride hu...

Re: Brompton Electric Conversion Advice please

I've converted a couple of Bromptons to electric for friends. Both using Nano motor kits. The radial spoking works fine, the rims look very strong. The battery on the newer kit was a 4aH Bosch, like that from a large Sds drill. It fits in an adapter in the front bag. Carrying the the folded bike in ...

Re: Schwalbe Marathon Vs Marathon Plus tyres.

I fitted Marathon Plus 29er tyres to my wife's ebike...they've been excellent and much better than std Marathons. After getting a flat from blackthorn following the hedge cutter, I put about 50ml 'Stans' fluid in the schraeder tubes; to date, no punctures after daily use on poor Cornish lanes. I've ...

Hi Phil, I've ridden many of the bridleways on Dartmoor; it's been very good this year due to the lack of rain. Look on the Dartmoor National Park website for info. on campsites, wild camping and mtb routes etc. Along with the OS 1:25000, there is also a very useful on/off road cycle map (Hartley?) ...

I've used Puma ones from Specsavers for the last 4 years; clear, orange and dark lenses. Really good and about £90.

Re: Compact double road

Hi Si, If you are really only using the little chainring on your compact double, why not give 1 x 10 a try on the gravel bike. I have done just done it on my trail mtb. Sunrace MX5 11-40 cassette, 32 tooth narrow wide chainring, 104 bcd, bolted to inside of Deore chainset, has good chainline. The na...

Re: Find a MTB triple chainset in SILVER, 165mm cranks

I recommend trying a 'range extender' rear cog, 40 tooth for your cassette. I've done a few of these for people, albeit on 10 speeds. There's no reason it shouldn't work with ( speed and your LX mech. It's a very neat solution, and you don't change your front set up.
