That windproof running jacket is a stupid price
I bought the full suite of 3 of those tops (the windproof, the waterproof and the thermal). I was mathematically on the edge of L and XL. As they looked snug on the models, I went XL and regret it. They'll be ok, but they are baggier than I choose.
It will depend. I tried 55 chainline on one of my boost bikes but it was obviously not the ideal for that bike. Hopefully you can make them work ok for your setup.
Yes sure it's not optimal however did you put the 2.5mm spacer on the non drive side to give you a quasi 52mm boost chainline.
While this still sounds too good to be true, I am perhaps just lucky that I currently have 10mm chainring clearance to the stay on a 30t with a Boost 52mm chainset. But I can see that perhaps a 34t wouldn't work indeed.
Chainreaction/Wiggle fire sale of 2023 - coming to an Ebay near you soon. It seems £40 is the going mark up for the running jackets.
I don't get the "not worth £150" comments. As somebody who overheats riding hard in a regular waterproof this may be be the best tenner I've ever parted with. Not sure I'll trust it with a backpack however.
I brought the waterproof and windproof not realising they were running jackets. Ordered in XL so expecting/hoping they'll be on the looser side (6'2, 14 and a bit stone). I'll find out in a couple of days when they turn up. Either way, a bargain for £25 for both.
Got some five tens from Evans and some trousers from decathlon (not discounted). I've spent more on cycle clothing in the last few days than I've spent on cycle clothing in the last 6-7 years.
I have a 52mm chainline on a 135mm frame (Deore 12 speed), equivalent to 55mm chainline on a boost frame, backpedalling in the 51t sprocket the chain never falls off. I'd say if you don't use the lower gears too much 55mm is fine. For Shimano 55mm chainline there are 2x 3mm spacers (one each side to achieve the 55mm chainline, so Q-Factor is 178mm compared to 172mm) in addition to the 2.5mm DS spacer. So you could move either the 3mm or 2.5mm spacer to the NDS if your cranks clear the chainstay. The 3mm spacer goes on the outside of the BB so you wouldn't have to remove the BB if wanted to move that. SRAM 55mm chainline are achieved by offsettting the chainring and there are no additional 3mm spacers.
The trick with chainline imo on 1x is to see if it physically fits, and then forget about it. Nobody can even agree what the best chainline really is- it's logical for it to be the middle but you spend more time in the lower gears, but then the different sizes also wear differently and have slightly different chain angle considerations anyway because of tooth shaping... If it works it works, none of my 3 bikes have the same chainline. We're a long way from worrying about crossover gears.
Yep Shimano switched boost from 52 to 55mm quietly in 2021, with no real explanation. My take is if you spend most of your time doing uplifts and so in the smaller cogs go 55mm. If you spend most of your time like me wheezing away in the big cogs then 52 is better. I doubt 3mm or 1 cog makes much difference though.
For Shimano 55mm chainline there are 2x 3mm spacers (one each side to achieve the 55mm chainline, so Q-Factor is 178mm compared to 172mm) in addition to the 2.5mm DS spacer.
Silly question but do those 3mm spacers come with the cranks or a BB?
Currently I have a SLX 12 speed chainset that gives me a 52mm chainline and the shifting is perfect.
I am expecting a M8120 XT chainset so I was planning to swap the 2.5mm to the non drive side to retain 52.5mm. But now I am a bit confused about the 3mm spacers that you mention. Do I need to fit them at all ? (if they come with the chainset).
Or is there a Super Boost 55mm BB ?
The 3mm spacers come with the cranks and yes you need them both otherwise the axle will be too long to achieve preload.
They are actually 2.5mm spacers Nick and come with the BB. If your frame BB shell is 73mm then you fit just one on the drive side. If its 68mm then 1 NDS and 2 DS. Shimano mtb cranks need a BB spaced at 95.5mm to the outside of the BB.
Shimano MTB threaded cups are 10mm so on your 73mm frame BB shell from left to right (NDS to DS) 10+73+2.5+10=95.5mm
I would just fit the M8120 as specified with one spacer on the drive side and see how you get on
Yes, you need the 2x 3mm spacers ( they should come with the crankset) as M8120 axle is 6mm longer than the SLX M7100 axle. You might be OK with a 55mm chainline - one 3mm spacer each side or just move the 3mm DS spacer to NDS to keep your 52mm chainline but your Crankset centre will off compared to the centre of the BB.
You cannot fit the M8120 crankset without the 2x 3mm spacers as stated above.
Cheers Andy. I am aware of the 2.5mm spacer which I currently use on the DS with my 73mmm shell but others are saying that the 3mm spacers comes in addition, one on each side, to yield a 55mm CL. I was considering putting the 2.5mm spacer on the NDS for a 52.5 CL.
Either way thanks to the 3 of you and I should probably stop the digression.
Yes sorry Nick just checked the M8120 chainset that came from CRC today. It has an axle length of 121mm as opposed to 115 for SLXm7100 and comes with 2 x 3mm spacers.
So yes, correct, you need; BB Installed with one 2.5mm BB spacer on Ds. Chainset installed with 1 x 3mm on DS and 1 x 3mm non Ds
Yes Andy except I'll try and test the 2.5mm BB spacer on the NDS on purpose as my chainring as loads of clearance. I do use the 2 biggest cogs quite a lot on the South Downs.
I can't remember if there is any leeway to adjust my cleats to offset for the imbalance created.

Funky designs, as seen on Olympic BMXers. Bought my son some for Xmas. And me some for me.
Even at £65 or so with 25% off it still starts at £85. For a push bike tyre 😂.
Keep missing these! Bah.
Took the opportunity to get a couple of those Ragley bars, I mean a fiver for a decent bar is not to be sniffed at. And a set of nukeproof neuron evo pedals for a tenner.
Those Ragley bars are lovely and light. Around 300g is very decent.
The H.Samuel Garmin Epic 2 for £375 is back up. Dispatch confirmed today.
Just bought their Down jacket which was £100(originally £250) so a fair saving and im in need of one anyway as my alpkit is rather tatty, with poorly stitched up rips.
So apparently theres an extra10' which is either 10% off or a tenner off the price and which I applied at checkout, and was accepted, but the price has remained at £100, not £90 that you'd expect.
Receipt to paypal is also £100. So anyone know what the score is here 😕

Was looking at the £15 turbo trainer but realised it's not thru axle compatible. So just bought lifeline rollers for £44 delivered

Always wanted to try rollers, just can't say no at that price.

PX bib longs on offer at £19.99 plus p&p
Ok , so they won't be the best quality ever , but for commuting use cheap enough to keep in your locker at work if you get wet on the way in.

South Downs Bikes currently have the Wahoo Kickr Move at £999, which is less than they are selling the normal Kickr v6 for and the same price Condor is selling the Kickr v6 for.
you can always lock out the fore/aft movement if you don’t like it and just have the increased lateral movement that the Move addition provides over and above the standard feet, which means I can dump the sorbothane pads that I have always used on my v1 Kickr to provide some lateral movement.

I ordered one of the £1 Ron Hill beanies, in flouro yellow.
Hopefully won't get mistaken for The Edge when out running.
They also had some Ron Hill running shorts for £2.25 and £2.80 in stock.
And a lifeline track pump for £9 - perhaps not outrageously cheap but I need one for the van anyway.

Silly prices for some Nukeproof lower headsets. The bearings are stainless steel with titanium coated races, so if you can get these to work in an existing headset, £2.99 for the bearings alone seems a steal!

£2.99 for the bearings alone seems a steal!
I'm 95% certain that's really helpful thanks PJay, I think the bearing dimensions work for a couple of headsets I use.
The comment says that the GX Chainset non-boost linked to above is actually Super-Boost...
Did anyone order the bargain xt 12 speed rear mech posted up by @pobaker ??
I ordered 3 (postage was then free!), but my parcel arrived today containing 3 Shimano MT401 brake levers and nothing else...
Have raised through Amazon but wondering if others have had the same issue!
I ordered 2 - they show as out for delivery today apparently with FedEx. Will let you know what is in the box when they arrive! It had better be a rear mech as mine is broken and have been waiting to fit it!!
@nre Same here. 3 ordered. Box of 3 x BL-MT401-L arrived today. Have messaged seller.
I ordered one mech and a single BL-mt401 lever arrived.
I'm surprised that people thought some random Amazon seller would sell current XT mechs at well below retail price, I was sure they'd either be fake or an incorrect part. Not that it makes it right, but I suppose Amazon will sort it.
Right, sounds like we're unlikely to get the mechs we ordered then! Through anyone other than Amazon I wouldn't have risked it, but decided it was worth a try! Oh well, my 12spd upgrade just got a bit more pricey!
The comment says that the GX Chainset non-boost linked to above is actually Super-Boost…
It is. And to be fair it's OK on a boost frame with the right spacers...I hope. I can let you know later this week.
The comment says that the GX Chainset non-boost linked to above is actually Super-Boost…
I’m sure I’ve heard it said that the spindles can be pressed out of these. So if you have the correct length spindle from
another chainset you might be ok.
Edit: perhaps like this
Has anyone gone through the returns process for the mech yet? I've been given a return address in France and postage isn't covered. I thought amazon market place returns had to be UK based addresses. Can't find anywhere to contact amazon directly just keep going round in circles with a chat bot.
Keep asking the chatbot to talk to a person
Generally, they will give you ~£12 back in postage, and you can insist to get them to refund all of it
