I go that way with the Brompton and always push up it - and I would describe myself as reasonably fit. I've never tried to get the road bike up there - I guess I could probably manage the slope but the slope with the roots would defeat me. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=17618#post-247090 Tue, 18 Apr 2017 08:46:15 +0000 Dave 247090@http://citycyclingedinburgh.info/bbpress/ <p>Start by getting a <a href="http://www.wiggle.co.uk/ta-110-pcd-zephyr-inner-road-chainring/">33t 110 BCD chainring</a>, it should be a straight swap. At the moment you have to ride at ~6mph at 60rpm, with the new ring it will drop to ~5.5mph so you should definitely feel it.</p> <p>Then if you take a look at the rear derailleur on your bike, specifically the length of the part that has the two cogs on it, does it look like <a href="http://www.wigglestatic.com/product-media/5360107155/shimano-tiagra-4700-rear-mech.jpg?w=430&amp;h=430&amp;a=7">this</a> (short cage) or like <a href="http://www.wigglestatic.com/product-media/5360107154/shimano-tiagra-4700-rear-mech-gs.jpg?w=430&amp;h=430&amp;a=7">this</a> (long cage)?</p> <p>It's hard to tell from the catalog pic but I'd suspect and hope for the latter. If so it should take an 11-32t cassette with no other modification. You should be able to get one for £25 delivered from wherever. </p> <p>That will let you ride slower still (~0.8mph slower @ 60rpm). </p> <p>You'll want a new chain anyway because probably the existing one has worn a bit since 2013 - but needless to say you need a few more links.</p> <p>It's not hard to do. Probably one of the easier DIY jobs IMO. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=17618#post-247084 Tue, 18 Apr 2017 01:40:06 +0000 Chug 247084@http://citycyclingedinburgh.info/bbpress/ <p>Hi livd. I have pretty much the same bike and had a similar issue - I wanted to degear it to tow offspring. Hannah at the cycleservice shop swapped the 36 ring for a 34 and it's been great for me. I reckon it gave me two extra gears below the original range. No need to change shifters etc. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=17618#post-247074 Mon, 17 Apr 2017 21:38:57 +0000 chdot 247074@http://citycyclingedinburgh.info/bbpress/ <p>"<em>Not</em> a suggested solution"</p> <p>You did notice the price(?) </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=17618#post-247073 Mon, 17 Apr 2017 21:36:00 +0000 ivangrozni 247073@http://citycyclingedinburgh.info/bbpress/ <p><blockquote>"You'd just about be going backwards with a cog that big =/"</blockquote></p> <p>Going backwards financially more than likely too - those SRAM cassettes cost a small fortune!</p> <p>Sugino XD2 chainsets are an affordable option if you're changing to triple - with the advantage that you can get the granniest of granny rings (the BCD is quite small from memory -good for touring as well as going up cliffs).

On a couple of my bikes I have Sugino OX601D crank sets. These are doubles but you can put something like a 46 big ring and a 30 inner. Downside is they are quite expensive at c£209 from Hubjub. On another bike with a compact crankset (50x34) I use a Wolftooth road link. It's only about £24. It fits onto your rear hanger and by dropping the rear mech allows you to fit a much bigger cassette. I use an 11-36 which allows me to get up a cliff face! It's dead easy to fit and works smoothly with my Shimano group set. I think I got it from Sigma Sport. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=17618#post-247063 Mon, 17 Apr 2017 20:07:23 +0000 Frenchy 247063@http://citycyclingedinburgh.info/bbpress/ <p>@chdot </p> <p>Thanks, that's very useful! </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=17618#post-247061 Mon, 17 Apr 2017 19:48:23 +0000 ih 247061@http://citycyclingedinburgh.info/bbpress/ <p>"<em>I feel better briefed on the subject now to have a chat with LBS.</em>"</p> <p>Great plan! </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=17618#post-247060 Mon, 17 Apr 2017 19:43:28 +0000 chdot 247060@http://citycyclingedinburgh.info/bbpress/ <p>"I feel like I'm trying to cycle uphill through treacle!"</p> <p>Don't know about the treacle, but it's a bit better than it once was.

Someone replies that it makes an amazing difference. You would need to check your chain is long enough (or get a new one - not expensive) and check the rear derailleur can cope with the additional ratio.

I apparently have me the lowest range cassette that will work with my chainrings on my road bike - and I'm wondering how this was worked out. Not because I don't believe it, but because I'm curious, and might want to repeat the trick on other bikes. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=17618#post-247053 Mon, 17 Apr 2017 19:14:59 +0000 gembo 247053@http://citycyclingedinburgh.info/bbpress/ <p>Sounds like 11-28 then to me. So if I am right (not great with cogs) the set up was at the tough end of 2x. Some 2x have a wider range and indeed the new 2x11 must also be a bit easier I guess. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=17618#post-247052 Mon, 17 Apr 2017 19:01:19 +0000 LivM 247052@http://citycyclingedinburgh.info/bbpress/ <p>I counted 11 on the small cog and pretty sure that the biggest cog had 28t printed on it.

I have a triple I can let you have with bottom bracket. If you need a new BB, say for instance for size of mine is wrong, they only cost a tenner from Spa Cycles.</p> <p>I could even do the swap if you wanted. It depends on what crank you have. I have a Stonglight Impact crank with 28/38/48, a Bottom bracket and shifter. You'd just need a left STI for a triple, which I may also have in a drawer.</p> <p>(basically I had a CX 9 speed Sora which when I sore out the BB, I changed from 2x9 to 3x9 with the Stronglight, + BB &amp; new Shifter. I could just do a stright swap? Depends on what spec you want, Shifters are thumb release not behind the brake leaver. You can buy new leavers to give you a triple for around £110 online.)</p> <p>Dave C </p>
